Accounting Policies [Abstract] | |
Significant Accounting Policies | 2. SIGNIFICANT ACCOUNTING POLICIES Principles of consolidation The Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingencies at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such estimates and assumptions relate to the useful lives of fixed assets and identified intangible assets, recoverability of long-lived assets, fair value of short-term and long-term investments, allowances for doubtful accounts, potential excess, obsolete or unmarketable inventory, potential reserves relating to litigation matters, accrued liabilities, accrued taxes, deferred tax valuation allowances, assumptions pertaining to share-based payments, and other reserves. Actual results could differ from those based on these estimates and assumptions, and such differences may be material to the financial statements. Foreign currency translation The financial statements of Vicor Japan Company, Ltd. (“VJCL”), a majority-owned subsidiary, for which the functional currency is the Japanese Yen, have been translated into U.S. Dollars using the exchange rate in effect at the balance sheet date for balance sheet amounts and the average exchange rates in effect during the year for income statement amounts. The gains and losses resulting from the changes in exchange rates from year to year have been reported in other comprehensive income. Transaction gains and losses resulting from the remeasurement of foreign currency denominated assets and liabilities of the Company’s foreign subsidiaries where the functional currency is the U.S. Dollar are included in other income (expense), net. Foreign currency gains (losses) included in other income (expense), net, were approximately $181,000, $(108,000), and $ ( 260,000) in 2020, 2019, and 2018, respectively. Investments The Company’s principal sources of liquidity are its existing balances of cash and cash equivalents and short-term investments, as well as cash generated from operations. Consistent with the guidelines of the Company’s investment policy, the Company can invest, and has historically invested, its cash balances in demand deposit accounts, money market funds, government debt securities, and auction rate securities meeting certain quality criteria. Cash and Cash Equivalents Cash and cash equivalents are highly liquid investments with insignificant interest rate risk and maturities of 90 days or less at the time of acquisition. Cash and cash equivalents include funds held in disbursement (i.e., checking) and money market accounts, certificates of deposit, and debt securities with maturities of less than three months at the time of purchase. Cash and cash equivalents are valued at cost, approximating market value. The Company’s money market securities are purchased and redeemed at par value. Their estimated fair value is equal to their cost, and, due to the nature of the securities and their classification as cash equivalents, there are no unrealized gains or losses recorded at the balance sheet dates. Short-term Investments The Company’s short-term investments, consisting of obligations of the U.S. Treasury, are debt securities with original maturities greater than three months but less than one year the time of purchase. Long-term Investment The Company’s long-term investment is an auction rate debt security with a maturity of greater than one year and is subject to credit, liquidity, market, and interest rate risk. Available-For-Sale Certain of the cash and cash equivalents, all of the short-term investments and the long-term investment are classified as available-for-sale non-credit The Company periodically evaluates the long-term investment to determine if impairment is required, whether an impairment is other than temporary, and the measurement of an impairment loss. The Company considers a variety of impairment indicators such as, but not limited to, a significant deterioration in the earnings performance, credit rating, or asset quality of the investment. The amortized cost of the debt securities are adjusted for amortization of premiums and accretion of discounts to maturity, the net amount of which, along with interest and realized gains and losses, is included in “Other income (expense), net” in the Consolidated Statements of Operations. Fair value measurements The Company accounts for certain financial assets at fair value, defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. A three-level hierarchy is used to show the extent and level of judgment used to estimate fair value measurements: Level 1 Inputs used to measure fair value are unadjusted quoted prices available in active markets for the identical assets or liabilities as of the reporting date. Level 2 Inputs used to measure fair value, other than quoted prices included in Level 1, are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in inactive markets. Level 2 also includes assets and liabilities valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument. Level 3 Inputs used to measure fair value are unobservable inputs supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The carrying amounts of cash and cash equivalents, short-term investments, accounts receivable, and accounts payable approximate fair value because of the short maturities of these financial instruments. Inventories Inventories are valued at the lower of cost (determined using the first-in, first-out Inventory estimated to be excess, obsolete, or unmarketable is written down to net realizable value. The Company’s estimation process for assessing net realizable value is based upon management’s estimate of expected future utility which is derived based on backlog, historical consumption and expected market conditions. If the Company’s estimated demand and/or market expectations were to change or if product sales were to decline, the Company’s estimation process may cause larger inventory reserves to be recorded, resulting in larger charges to cost of revenues. Concentrations of risk Financial instruments potentially subjecting the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and short-term investments, of which a significant portion are held by three financial institutions, its long-term investment, and trade accounts receivable. The Company maintains cash and cash equivalents, short-term investments and certain other financial instruments with high credit counterparties, and continuously monitors the amount of credit exposure to any one issuer and diversifies its investments in order to minimize its credit risk. Generally, amounts invested with these financial institutions are in excess of federal deposit insurance limits. The Company has not experienced any losses in such accounts, and management believes the Company is not exposed to significant credit risk. The Company’s long-term investment as of December 31, 2020 consists of a single auction rate security with a par value of $3,000,000, which is collateralized by student loans. It is a highly rated (Aaa/AA+) municipal and corporate debt security. Through December 31, 2020, auctions held for the Company’s auction rate security have failed. The funds associated with an auction rate security that has failed auction may not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the security is called, or the underlying securities have matured. If the credit rating of the issuer of the auction rate security held deteriorates, the Company may be required to adjust the carrying value of the investment for an other-than-temporary decline in value through an impairment charge. The Company’s investment policy, approved by the Board of Directors, limits the amount the Company may invest in any issuer, thereby reducing credit risk concentrations. The Company’s products are sold worldwide to customers ranging from smaller, independent manufacturers of highly specialized electronic devices, to larger OEMs, ODMs and their contract manufacturers. See Note 19, Segment Information , for a discussion of a change to segment reporting in the second quarter of 2019. The Company’s Brick Products’ customers are primarily concentrated in the following industries: aerospace and defense electronics, industrial automation, industrial equipment, instrumentation and test equipment, and transportation (notably in rail and heavy equipment applications). The Company’s Advanced Products’ customers are concentrated in the data center and hyperscaler segments of enterprise computing, in which the Company’s products are used for voltage distribution on server motherboards, in server racks, and across datacenter infrastructure The Company also targets applications in aerospace and aviation, defense electronics, industrial automation, instrumentation, test equipment, solid state lighting, telecommunications and networking infrastructure, and vehicles (notably in the autonomous driving, electric vehicle, and hybrid vehicle niches of the vehicle segment). While, overall, the Company has a broad customer base and sells into a variety of industries, a substantial portion of the Company’s revenue from its Advanced Products line has been derived from a limited number of customers. This concentration of revenue is a reflection of the relatively early stage of adoption of the technologies, architectures and products offered in the Advanced Products line, and the Company’s strategy of targeting market leading innovators as initial customers for its Advanced Products. Concentrations of credit risk with respect to trade accounts receivable are limited due to the number of entities comprising the Company’s customer base. As of December , and , customer accounted for approximately % and %, respectively, of trade account receivables. Components and materials used in the Company’s products are purchased from a variety of vendors. While most of the components are available from multiple sources, some key components for certain Advanced Products, in particular, are supplied by single vendors. In instances of single source items, the Company maintains levels of inventories management considers appropriate to enable meeting the delivery requirements of customers. If suppliers or subcontractors cannot provide their products or services on time or to the required specifications, the Company may not be able to meet the demand for its products and its delivery times may be negatively affected. Long-lived assets The Company reviews property, plant and equipment and finite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying value of such assets may not be recoverable. Management determines whether the carrying value of an asset or asset group is recoverable based on comparison to the undiscounted expected future cash flows the assets are expected to generate over their remaining economic lives. If an asset value is not recoverable, the impairment loss is equal to the amount by which the carrying value of the asset exceeds its fair value, which is determined by either a quoted market price, if any, or a value determined by utilizing a discounted cash flow technique. Evaluation of impairment of long-lived assets requires estimates of future operating results that are used in the preparation of the expected future undiscounted cash flows. Actual future operating results and the remaining economic lives of our long-lived assets could differ from the estimates used in assessing the recoverability of these assets. These differences could result in impairment charges, which could be material. Intangible assets Values assigned to patents are amortized using the straight-line method over periods ranging from three to years. Patents and other intangible assets are included in “Other assets” in the accompanying Consolidated Balance Sheets. Product warranties The Company generally offers a two-year Revenue recognition Revenue is recognized when control of the promised goods or services is transferred to a customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Sales, value add, and other taxes collected concurrent with revenue producing activities are excluded from revenue. The expected costs associated with product warranties continue to be recognized at the time product revenue is recognized. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of revenues. The Company’s primary source of net revenue comes from the sale of products, which are modular power components and power systems for converting, regulating and controlling electric current. The principal customers for the Company’s power converters and systems are large OEMs, ODMs and the original design manufacturers and contract manufacturers serving them, and smaller, lower volume users, which are broadly distributed across several major market areas. The Company recognizes revenue for product sales at a point in time following the transfer of control of such products to the customer, including sales to stocking distributors, which typically occurs upon shipment or delivery, depending on the terms of the underlying contract. The Company establishes sales allowances on shipments to stocking distributors for estimated future product returns including distributor returns and price adjustment credits, primarily based upon historical and anticipated rates of product returns and allowances. Certain contracts with customers contain multiple performance obligations, which typically may include a combination of non-recurring production units represent a separate distinct performance obligation. For such arrangements, revenue is allocated to each performance obligation based on its relative standalone selling price, based on prices charged to customers or using the expected cost plus a margin approach. The Company delays revenue recognition for NRE and prototype units until the point in time at which the final milestone under the NRE arrangement is completed and control is transferred to the customer, which is generally the shipment or delivery of the prototype. Revenue for production units is recognized upon shipment or delivery, consistent with product revenue summarized above . The Company licenses its intellectual property under right to use licenses, in which royalties due to the Company are based upon a percentage of the licensee’s sales. The Company utilizes the exception under the revenue recognition guidance for the recognition of sales- or usage-based royalties, in which the royalties are not recognized until the later of when 1) the customer’s subsequent sales or usages occur, or 2) the performance obligation to which some or all of the sales- or usage-based royalty has been allocated is satisfied or partially satisfied. Accounts receivable includes amounts billed and currently due from customers. The amounts due are stated at their estimated realizable value. The Company’s payment terms vary by the type and location of its customers and the products or services offered, although terms generally include a requirement of payment within 30 to 60 days. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, based on assessments of customers’ credit-risk profiles and payment histories. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company does not require collateral from its customers, although there have been circumstances when the Company has required cash in advance (i.e., a partial down-payment) to facilitate orders in excess of a customer’s established credit limit. To date, such amounts have not been material. The Company records deferred revenue, which represents a contract liability, when cash payments are received or due in advance of performance under a contract with a customer. During the years ended December 31, 2020 and 2019, the Company recognized revenue of approximately $3,550,000 and $76,000, respectively, that was included in deferred revenue at the beginning of the respective period. The Company applies the practical expedient for the incremental costs of obtaining a contract for sales commissions, which are expensed when incurred because the amortization period is generally less than one year. These costs are included in selling, general and administrative expenses. The Company also applies another practical expedient and does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. Advertising expense The cost of advertising is expensed as incurred. The Company incurred approximately $2,637,000, $2,749,000, and $2,610,000 in advertising costs during 2020, 2019, and 2018, respectively. Legal Costs Legal costs in connection with litigation are expensed as incurred. Stock-based compensation The Company uses the Black-Scholes option-pricing model to calculate the fair value of stock option awards, whether they possess time-based vesting provisions or performance-based vesting provisions, and awards granted under the Vicor Corporation 2017 Employee Stock Purchase Plan (“ESPP”), as of their grant date. For stock options with time-based vesting provisions, the calculated compensation expense, net of expected forfeitures, is recognized on a straight-line basis over the service period of the award, which is generally five years for stock options. For stock options with performance-based vesting provisions, recognition of compensation expense, net of expected forfeitures, commences if and when the achievement of the performance criteria is deemed probable. For stock options with performance-based vesting provisions, compensation expense, net of expected forfeitures, when recognized, is recognized over the relevant performance period. Income taxes Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted income tax rates and laws expected to be in effect when the temporary differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if management determines it is more likely than not that some portion or all of the deferred tax assets will not be realized. All deferred tax assets and liabilities are classified as noncurrent. The Company follows a two-step “more-likely-than-not” “more-likely-than-not” Net income per common share The Company computes basic net income per share using the weighted average number of common shares outstanding and diluted net income per share using the weighted average number of common shares outstanding plus the effect of outstanding dilutive stock options, if any. The following table sets forth the computation of basic and diluted net income per share for the years ended December 31 (in thousands, except per share amounts): 2020 2019 2018 Numerator: Net income attributable to Vicor Corporation $ 17,910 $ 14,098 $ 31,725 Denominator: Denominator for basic net income per share-weighted average shares (1) 42,186 40,330 39,872 Effect of dilutive securities: Employee stock options (2) 1,683 1,347 857 Denominator for diluted net income per share-adjusted weighted-average shares and assumed conversions (3) 43,869 41,677 40,729 Basic net income per share $ 0.42 $ 0.35 $ 0.80 Diluted net income per share $ 0.41 $ 0.34 $ 0.78 (1) Denominator represents weighted average number of Common Shares and Class B Common Shares outstanding. (2) Options to purchase 181,196, 164,367 and 67,247 shares of Common Stock in 2020, 2019, and 2018, respectively, were not included in the calculation of net income per share as the effect would have been antidilutive. (3) Denominator represents weighted average number of Common Shares and Class B Common Shares outstanding for the year, adjusted to include the dilutive effect, if any, of outstanding options. Comprehensive income (loss) The components of comprehensive income (loss) include, in addition to consolidated net income (loss), unrealized gains and losses on investments, net of tax and foreign currency translation adjustments related to VJCL, net of tax. Impact of recently issued accounting standards In December 2019, the FASB issued guidance designed to simplify the accounting for income taxes by eliminating certain exceptions to the general principles in Topic 740, Income Taxes In August 2018, the FASB issued guidance which modifies the disclosure requirements on fair value measurements under Topic 820, Fair Value Measurements, including the consideration of costs and benefits. The new guidance is effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2019, with early adoption permitted. It is required to be applied on a retrospective approach with certain elements being adopted prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. The Company adopted the new guidance as of January 1, 2020. The adoption did not have a material impact on the Company’s consolidated financial statements and disclosures. In June 2016, the FASB issued new guidance which will require measurement and recognition of expected credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale Other new pronouncements issued but not effective until after December 31, 2020 are not expected to have a material impact on the Company’s consolidated financial statements. |

Investments, Debt and Equity Securities [Abstract] | |
Short-Term and Long-Term Investments | 4. SHORT-TERM AND LONG-TERM INVESTMENTS As of December 31, 2020 the Company held $50,166,000 of short-term investments, consisting of obligations of the U.S. Treasury, all of which were debt securities with original maturities greater than three months but less than one year the time of purchase. As of December 31, 2020 and 2019, the Company held one auction rate security with a par value of $3,000,000, purchased through and held in custody by a broker-dealer affiliate of Bank of America, N.A., that has experienced failed auctions (the “Failed Auction Security”) since February 2008. The Failed Auction Security held by the Company is Aaa/AA+ rated by major credit rating agencies, is collateralized by student loans, and is guaranteed by the U.S. Department of Education under the Federal Family Education Loan Program. Management is not aware of any reason to believe the issuer of the Failed Auction Security is presently at risk of default. Through December 31, 2020, the Company has continued to receive interest payments on the Failed Auction Security in accordance with the terms of its indenture. Management believes the Company ultimately should be able to liquidate the Failed Auction Security without significant loss primarily due to the overall quality of the issue held and the collateral securing the substantial majority of the underlying obligation. However, current conditions in the auction rate securities market have led management to conclude the recovery period for the Failed Auction Security exceeds 12 months. As a result, the Company continued to classify the Failed Auction Security as long-term as of December 31, 2020. Details of our investments are as follows (in thousands): December 31, 2020 Cash and Cash Equivalents Short-Term Investments Long-Term Investments Measured at fair value: Available-for-sale Money Market Funds $ 69,493 $ — $ — U.S. Treasury Obligations 19,998 50,166 — Failed Auction Security — — 2,517 Total 89,491 50,166 2,517 Other measurement basis: Cash on hand 72,251 — — Total $ 161,742 $ 50,166 $ 2,517 December 31, 2019 Cash and Cash Equivalents Short-Term Investments Long-Term Investments Measured at fair value: Available-for-sale Money Market Funds $ 9,630 $ — $ — Failed Auction Security — — 2,510 Total 9,630 — 2,510 Other measurement basis: Cash on hand 75,038 — — Total $ 84,668 $ — $ 2,510 The following is a summary of the available-for-sale December 31, 2020 Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value U.S. Treasury Obligations $ 70,172 $ — $ 8 $ 70,164 Failed Auction Security 3,000 — 483 2,517 December 31, 2019 Failed Auction Security $ 3,000 $ — $ 490 $ 2,510 As of December 31, 2020 and 2019, the Failed Auction Security had been in an unrealized loss position for greater than 12 months. The amortized cost and estimated fair value of the available-for-sale by type and contractual maturities, are shown below (in thousands): U.S. Treasury Obligations: Cost Estimated Fair Maturities greater than three months but less than one year $ 50,174 $ 50,166 Maturities less than three months 19,998 19,998 $ 70,172 $ 70,164 Failed Auction Security: Cost Estimated Fair Due in twenty to forty years $ 3,000 $ 2,517 Based on the fair value measurements described in Note 5, the fair value of the Failed Auction Security on December 31, 2020, with a par value of $3,000,000, was estimated by the Company to be approximately $2,517,000. The gross unrealized loss of $483,000 on the Failed Auction Security consists of two types of estimated loss: an aggregate credit loss of $33,000 and an aggregate temporary impairment of $450,000. In determining the amount of credit loss, the Company compared the present value of cash flows expected to be collected to the amortized cost basis of the security, considering credit default risk probabilities and changes in credit ratings as significant inputs, among other factors (see Note 5). The following table represents a rollforward of the activity related to the credit loss recognized in earnings on the Failed Auction Security held by the Company for the years ended December 31 (in thousands): 2020 2019 2018 Balance at the beginning of the period $ 37 $ 41 $ 48 Reductions in the amount related to credit gain for which other-than-temporary impairment was not previously recognized (4 ) (4 ) (7 ) Balance at the end of the period $ 33 $ 37 $ 41 At this time, the Company has no intent to sell the Failed Auction Security and does not believe it is more likely than not the Company will be required to sell the security. If current market conditions deteriorate further, the Company may be required to record additional unrealized losses. If the credit rating of the security deteriorates, the Company may be required to adjust the carrying value of the investment through impairment charges recorded in the Consolidated Statement of Operations, and any such impairment adjustments may be material. Based on the Company’s ability to access cash and cash equivalents, its short-term investments, and its expected operating cash flows, management does not anticipate the current lack of liquidity associated with the Failed Auction Security held will affect the Company’s ability to execute its current operating plan. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 5. FAIR VALUE MEASUREMENTS The Company accounts for certain financial assets at fair value, defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions market participants would use in pricing an asset or liability. A three-level hierarchy is used to show the extent and level of judgment used to estimate fair value measurements. Assets and liabilities measured at fair value on a recurring basis included the following as of December 31, 2020 (in thousands): Using Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value as of December 31, 2020 Cash equivalents: Money market funds $ 69,493 $ — $ — $ 69,493 U.S. Treasury Obligations 19,998 — — 19,998 Short-term investments: U.S. Treasury Obligations 50,166 — — 50,166 Long-term investments: Failed Auction Security — — 2,517 2,517 Liabilities: Contingent consideration obligations — — (227 ) (227 ) Assets measured at fair value on a recurring basis included the following as of December 31, 2019 (in thousands): Using Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value as of December 31, 2019 Cash equivalents: Money market funds $ 9,630 $ — $ — $ 9,630 Long-term investments: Failed Auction Security — — 2,510 2,510 Liabilities: Contingent consideration obligations — — (451 ) (451 ) As of December 31, 2020, there was insufficient observable auction rate security market information available to determine the fair value of the Failed Auction Security using Level 1 or Level 2 inputs. As such, the Company’s investment in the Failed Auction Security was deemed to require valuation using Level 3 inputs. Management, after consulting with advisors, valued the Failed Auction Security using analyses and pricing models similar to those used by market participants (i.e., buyers, sellers, and the broker-dealers responsible for execution of the Dutch auction pricing mechanism by which each issue’s interest rate was set). Management utilized a probability weighted discounted cash flow (“DCF”) model to determine the estimated fair value of this security as of December 31, 2020. The major assumptions used in preparing the DCF model included: estimates for the amount and timing of future interest and principal payments based on default probability assumptions used to measure the credit loss of 1.0%; the rate of return required by investors to own this type of security in the current environment, which we estimate to be 5.0% above the risk free rate of return; and an estimated time frame of three to for successful auctions for this type of security to occur. In making these assumptions, management considered relevant factors including: the formula applicable to each security defining the interest rate paid to investors in the event of a failed auction (the “Penalty Rate”); forward projections of the interest rate benchmarks specified in such formulas; the likely timing of principal repayments; the probability of full repayment considering the guarantees by the U.S. Department of Education of the underlying student loans, guarantees by other third parties, and additional credit enhancements provided through other means; and publicly available pricing data for recently issued student loan asset-backed securities not subject to auctions. In developing its estimate of the rate of return required by investors to own these securities, management compared the Penalty Rate of the Failed Auction Security with yields of actively traded long-term bonds with similar characteristics and, reflecting the limited liquidity for auction rate securities and the discounts to par value seen in recent tender offers by issuers and arm’s length market transactions between informed buyers and sellers, estimated the implied yield (i.e., the discount to par value) necessary to complete a sale of the Failed Auction Security. Management has calculated an increase or decrease in the liquidity risk premium of % referenced above of % (i.e., 100 basis points) as used in the model, would decrease or increase, respectively, the fair value of the Failed Auction Security by approximately $ . The significant unobservable inputs used in the fair value measurement of the Company’s Failed Auction Security are the cumulative probability of earning the maximum rate until maturity, the cumulative probability of principal return prior to maturity, the cumulative probability of default, the liquidity risk premium, and the recovery rate in default. Significant increases (decreases) in any of those inputs in isolation would result in changes in fair value measurement. Significant increases (decreases) in the cumulative probability of earning the maximum rate until maturity, the cumulative probability of principal return prior to maturity, and the recovery rate in default would result in a higher (lower) fair value measurement, while increases (decreases) in the cumulative probability of default and the liquidity risk premium would result in a (lower) higher fair value measurement. Generally, the interrelationships are such that a change in the assumption used for the cumulative probability of principal return prior to maturity is accompanied by a directionally similar change in the assumption used for the cumulative probability of earning the maximum rate until maturity and a directionally opposite change in the assumptions used for the cumulative probability of default and the liquidity risk premium. The recovery rate in default is somewhat independent and based upon the securities’ specific underlying assets and published recovery rate indices. Quantitative information about Level 3 fair value measurements as of December 31, 2020 are as follows (dollars in thousands): Fair Value Valuation Technique Unobservable Input Weighted Average Failed Auction Security $ 2,517 Discounted cash flow Cumulative probability of earning the maximum rate until maturity 0.14 % Cumulative probability of principal return prior to maturity 93.62 % Cumulative probability of default 6.23 % Liquidity risk premium 5.00 % Recovery rate in default 40.00 % The change in the estimated fair value calculated for the investment valued on a recurring basis utilizing Level 3 inputs (i.e., the Failed Auction Security) for the year ended December 31, 2020 was as follows (in thousands): Balance at the beginning of the period $ 2,510 Credit gain on available-for-sale 4 Gain included in Other comprehensive income 3 Balance at the end of the period $ 2,517 The Company has classified its contingent consideration obligations as Level 3 because the fair value for this liability was determined using unobservable inputs. The liability is based on estimated sales of legacy products over the period of royalty payments at the royalty rate (see Note 9), discounted using the Company’s estimated cost of capital. The change in the estimated fair value calculated for the liabilities valued on a recurring basis utilizing Level 3 inputs (i.e., the Contingent consideration obligations) for the year ended December 31, 2020 was as follows (in thousands): Balance at the beginning of the period $ 451 Payments (224 ) Balance at the end of the period $ 227 There were no transfers between Level 1 and Level 2 of the fair value hierarchy during the year ended December 31, 2020. |

Class B Common Stock is convertible at the option of the holder thereof at any time and without cost to the stockholder into shares of Common Stock on a one-for-one In November 2000, the Board of Directors of the Company authorized the repurchase of up to $30,000,000 of the Company’s Common Stock (the “November 2000 Plan”). The plan authorizes the Company to make repurchases from time to time in the open market or through privately negotiated transactions. The timing of this program and the amount of the stock that may be repurchased is at the discretion of management based on its view of economic and financial market conditions. There were no repurchases under the November 2000 Plan in 2020, 2019, and 2018. On December 31, 2020, the Company had approximately $8,541,000 available for share repurchases under the November 2000 Plan. In June 2020, the Company completed an underwritten public offering of its Common Stock, resulting in the issuance of a total of 1,769,231 shares of registered Common Stock and net proceeds of approximately $109,714,000, after deduction of underwriting discounts and offering expenses. The Company intends to use the net proceeds from the offering to expand its manufacturing facilities and for other general corporate purposes. Dividends are declared at the discretion of the Company’s Board of Directors and depend on actual cash from operations, the Company’s financial condition and capital requirements and any other factors the Company’s Board of Directors may consider relevant at the time. Common Stock and Class B Common Stock participate in dividends and earnings equally. On December 31, 2020, 2019, and 2018, there were 21,852,334, 20,895,747, and 21,233,659, respectively, shares of Vicor Common Stock reserved for issuance upon exercise of Vicor stock options, upon conversion of Class B Common Stock and under the ESPP. |

Stock-Based Compensation and Employee Benefit Plans | 12. STOCK-BASED COMPENSATION AND EMPLOYEE BENEFIT PLANS Vicor currently grants options for the purchase of Common Stock (i.e., “stock options”) under the following equity compensation plans that are stockholder-approved: Amended and Restated 2000 Stock Option and Incentive Plan, as amended and restated (the “2000 Plan”) non-qualified non-employee Vicor Corporation 2017 Employee Stock Purchase Plan (the “Plan” or the “ESPP”) VI Chip Corporation (“VI Chip”) was a privately held, majority-owned subsidiary of Vicor until June 28, 2019, at which date it was merged with and into Vicor, and its separate corporate existence ceased (see Note 18). Until that time, VI Chip could grant stock options under the VI Chip Corporation Amended and Restated 2007 Stock Option and Incentive Plan Picor Corporation (“Picor”) was a privately held, majority-owned subsidiary of Vicor until May 30, 2018, at which date it was merged with and into Vicor, and its separate corporate existence ceased (see Note 18). Until that time, Picor could grant stock options under the Picor Corporation Amended and Restated 2001 Stock Option and Incentive Plan All time-based (i.e., non-performance-based) non-performance-based) Stock-based compensation expense for the years ended December 31 was as follows (in thousands): 2020 2019 2018 Cost of revenues $ 934 $ 342 $ 237 Selling, general and administrative 3,164 1,979 2,517 Research and development 1,785 715 642 Total stock-based compensation $ 5,883 $ 3,036 $ 3,396 The increase in stock option compensation expense in 2020 compared to 2019, was primarily due to an increase in the number of stock options granted and to the acceleration of recognition of compensation expense on stock options granted to retirement eligible employees, both associated with stock option awards in June 2020. Compensation expense by type of award for the years ended December 31 was as follows (in thousands): 2020 2019 2018 Stock options $ 4,982 $ 2,072 $ 2,649 ESPP 901 964 747 Total stock-based compensation $ 5,883 $ 3,036 $ 3,396 The fair value for non-performance-based 2020 2019 2018 Risk-free interest rate 0.5 % 1.8 % 2.9 % Expected dividend yield — — — Expected volatility 48 % 42 % 44 % Expected lives (years) 6.1 6.3 6.4 Risk-free interest rate: The Company uses the yield on zero-coupon Expected dividend yield: The Company determines the expected dividend yield by annualizing the most recent prior cash dividends declared by the Company’s Board of Directors, if any, and dividing that result by the closing stock price on the date of that dividend declaration. Dividends are not paid on options. Expected volatility: Vicor uses historical volatility to estimate the grant-date fair value of the options, using the expected term for the period over which to calculate the volatility (see below). The Company does not expect its future volatility to differ from its historical volatility. The computation of the Company’s volatility is based on a simple average calculation of monthly volatilities over the expected term. Expected term: The Company uses historical employee exercise and option expiration data to estimate the expected term assumption for the Black-Scholes grant-date valuation. The Company believes this historical data is currently the best estimate of the expected term of options, and all groups of the Company’s employees exhibit similar exercise behavior. Forfeiture rate: The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. The forfeiture analysis is re-evaluated Based on an analysis of historical forfeitures, the Company applied an annual forfeiture rate of 5.25% in 2020, 2019, and 2018, estimating approximately 85% of its options will actually vest in those three years. Vicor Stock Options A summary of the activity under the 2000 Plan as of December 31, 2020 and changes during the year then ended, is presented below (in thousands except for share and weighted-average data): Options Weighted- Weighted- Aggregate Outstanding on December 31, 2019 2,687,896 $ 10.81 Granted 354,075 $ 68.34 Forfeited and expired (69,987 ) $ 23.77 Exercised (948,507 ) $ 9.62 Outstanding on December 31, 2020 2,023,477 $ 20.98 4.87 $ 144,153 Exercisable on December 31, 2020 924,964 $ 9.05 3.41 $ 76,932 Vested or expected to vest as of December 31, 2020(1) 1,947,127 $ 20.22 4.79 $ 140,186 (1) In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. The number of options expected to vest is calculated by applying an estimated forfeiture rate to the unvested options. As of December 31, 2019 and 2018 the Company had options exercisable for 1,475,947 and 888,257 shares respectively, for which the weighted average exercise prices were $8.74 and $8.93, respectively. During the years ended December 31, 2020, 2019, and 2018, the total intrinsic value of Vicor options exercised (i.e., the difference between the market price at exercise and the price paid by the employee to exercise the options) was approximately $50,410,000, $6,636,000, and $22,938,000, respectively. The total amount of cash received by the Company from options exercised in 2020, 2019, and 2018, was $9,127,000, $2,437,000, and $6,782,000, respectively. The total grant-date fair value of stock options granted during the years ended December 31, 2020, 2019, and 2018 was approximately $10,847,000, $1,657,000, and $2,921,000, respectively. As of December 31, 2020, there was approximately $9,758,000 of total unrecognized compensation cost related to unvested non-performance The weighted-average fair value of Vicor options granted was $30.63, $14.30, and $17.46, in 2020, 2019, and 2018, respectively. 401(k) Plan The Company sponsors a savings plan available to all domestic employees, which qualifies under Section 401(k) of the Code. Employees may contribute to the plan in amounts representing from 1% to 80% of their pre-tax Stock Bonus Plan Under the Company’s 1985 Stock Bonus Plan, as amended, shares of Common Stock may be awarded to employees from time to time as determined by the Board of Directors. On December 31, 2020, 109,964 shares were available for further award. All shares awarded to employees under this plan have vested. No further awards are contemplated under this plan at the present time. |

Leases [Abstract] | |
Leases | 13. LEASES Substantially all of the Company’s leases are classified as operating leases. The majority of the Company’s leases are for office and manufacturing space, along with several automobiles and certain equipment. Leases with initial terms of less than twelve months are not recorded on the balance sheet. Expense for these leases is recognized on a straight-line basis over the lease term. The Company’s leases have remaining terms of less than one year to just over six years. The majority of the Company’s leases do not have options to renew, although several have renewal terms to extend the lease for one five-year term, and one lease contains two five-year renewal options. None of the renewal options are included in determining the term of the lease, used for calculating the associated lease liabilities. None of the Company’s leases include variable payments, residual value guarantees or restrictive covenants. A number of the Company’s leases for office and manufacturing space include provision for common area maintenance (“CAM”). The Company accounts for CAM separately from lease payments, and therefore costs for CAM are not included in the determination of lease liabilities. The Company is a party to one arrangement as the lessor, for its facility located in Sunnyvale, California, with a third party. The lessee under this lease has one option to renew the lease for a term of five years. As of December 31, 2020, the balance of ROU assets was approximately $4,449,000, and the balances of short-term and long-term lease liabilities were approximately $1,629,000 and $2,968,000, respectively. For the year ended December 31, 2020, the Company recorded operating lease cost, including short-term lease cost, of approximately $1,943,000 ($1,870,000 in 2019). The ROU assets are included in “Property, plant and equipment, net” in the accompanying Consolidated Balance Sheets. The maturities of the Company’s lease liabilities are as follows (in thousands): 2021 $ 1,740 2022 1,316 2023 883 2024 663 2025 317 Total lease payments $ 4,919 Less: Imputed interest 322 Present value of lease liabilities $ 4,597 As of December 31, 2020, the weighted-average remaining lease term was 3.4 years and the weighted-average discount rate was 3.00% for the Company’s operating leases. The Company developed the discount rates used based on a London Interbank Offered Rate (“LIBOR”) over a term approximating the term of the related lease, plus an additional interest factor, which was generally 1.375%. For the years ended December 31, 2020 and December 31, 2019, the Company paid approximately $ and $1,857,000, respectively, for amounts included in the measurement of lease liabilities through operating cash flows. The Company obtained approximately $ and $1,761,000 in ROU assets in exchange for $1,935,000 and $1,758,000 of new operating lease liabilities for the years ended December 31, 2020 and December 31, 2019, respectively. The maturities of the lease payments to be received by the Company under the lease agreement for its leased facility in California are as follows (in thousands): 2021 $ 901 2022 928 2023 955 2024 402 Total lease payments to be received $ 3,186 The Company recorded net lease income under this lease of approximately $ for each of the years ended December , , and . |

Severance and Other Charges | 14. SEVERANCE AND OTHER CHARGES In May 2018, the Company’s management authorized the closure of its Granite Power Technologies, Inc. (“GPT”) subsidiary, which was part of the former Brick Business Unit (“BBU”) segment, by the end of 2018. The closure was completed in December 2018. GPT, located in Manchester, N.H., was one of three Vicor Custom Power (“VCP”) entities. Certain of GPT’s products continue to be manufactured and sold by the two remaining VCP entities. As a result, the Company recorded a pre-tax charge of $ in the second quarter of 2018, for the cost of severance and other employee-related costs involving cash payments based on each employee’s respective length of service. This was recorded as “Severance and other charges” in the Consolidated Statement of Operations. Adjustments to reduce the charge were due to certain GPT employees accepting positions with Vicor, and for severance payments made to employees who had left GPT after the authorization of the closure. Adjustments to increase the charge, were due to an early termination fee under GPT’s lease and for freight costs to transport GPT inventory and fixed assets to the two remaining VCP entities. The adjustments were recorded in the third and fourth quarters of 2018 for a total expense of $ ,000 in 2018, as reported in the Consolidated Statement of Operations. |

In 2019, the Company utilized net operating loss carryforwards and tax credits to offset federal income tax expense. In 2018, the Company utilized net operating loss carryforwards to offset federal income tax expense. For financial reporting purposes, income before income taxes for the years ended December 31 include the following components (in thousands): 2020 2019 2018 Domestic $ 17,688 $ 13,493 $ 31,455 Foreign 773 1,394 1,478 $ 18,461 $ 14,887 $ 32,933 Significant components of the provision (benefit) for income taxes for the years ended December 31 are as follows (in thousands): 2020 2019 2018 Current: Federal $ 215 $ — $ — State 93 268 231 Foreign 252 450 911 560 718 1,142 Deferred: Foreign (21 ) 60 (55 ) (21 ) 60 (55 ) $ 539 $ 778 $ 1,087 The Tax Cuts and Jobs Act of 2017 (the “Tax Act”) eliminated the deferral of U.S. income tax on accumulated foreign earnings by imposing a one-time re-invested Significant components of the Company’s deferred tax assets and liabilities as of December 31 were as follows (in thousands): 2020 2019 Deferred tax assets: Research and development tax credit carryforwards $ 29,046 $ 27,607 Net operating loss carryforwards 5,923 328 Inventory reserves 2,282 1,522 Investment tax credit carryforwards 1,927 2,102 Stock-based compensation 1,796 1,587 Vacation accrual 1,349 1,280 UNICAP 1,336 351 Accrued payroll tax deferral 764 — Lease liabilities 518 679 Other 1,197 1,708 Total deferred tax assets 46,138 37,164 Less: Valuation allowance for deferred tax assets (37,856 ) (30,363 ) Net deferred tax assets 8,282 6,801 Deferred tax liabilities: Depreciation (6,809 ) (5,296 ) Prepaid expenses (616 ) (552 ) ROU assets (490 ) (653 ) Other (141 ) (95 ) Total deferred tax liabilities (8,056 ) (6,596 ) Net deferred tax assets (liabilities) $ 226 $ 205 As of December 31, 2020, the Company has a valuation allowance of ap proximately $37,856,000 against all net domestic deferred tax assets, for which realization cannot be considered more likely than not at this time. Management assesses the need for the valuation allowance on a quarterly basis. In assessing the need for a valuation allowance, the Company considers all positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and past financial performance. While recent positive operating results, as a result of increases in bookings, caused the Company to be in a cumulative income position as of December 31, 2020, the Company faces uncertainties in forecasting its operating results due to the continued impact of the COVID-19 pandemic on the Company’s supply chain, certain process issues with the production of Advanced Products and the unpredictability in certain markets. This operating uncertainty also makes it difficult to predict the availability and utilization of tax benefits over the next several years. As a result, management has concluded, at this time, is more likely than not the Company’s net domestic deferred tax assets will not be realized, and a full valuation allowance against all net domestic deferred tax assets is still warranted as of December 31, 2020. The valuation allowance against these deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance. If the positive quarterly earnings and increases in bookings continue, and the Company’s concerns about industry uncertainty and world events, including the impact of the COVID-19 The state and federal research and development tax credit carryforwards of approximately $11,344,000 and $19,423,000, respectively, expire beginning in 2020 for state purposes and in 2025 for federal purposes. The Company has federal net operating loss carryforwards generated after 2017 of approximately $24,990,000, which have an indefinite carryforward period and certain state operating loss carryforwards of approximately $10,241,000, which expire beginning in 2024. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): 2020 2019 2018 Balance on January 1 $ 2,070 $ 1,462 $ 1,104 Additions based on tax positions related to the current year 244 571 245 (Reductions) additions for tax positions of prior years (13 ) 43 120 Lapse of statute (4 ) (6 ) (7 ) Balance on December 31 $ 2,297 $ 2,070 $ 1,462 The Company has reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by a taxing authority. The total amount of unrecognized tax benefits, that is the aggregate tax effect of differences between tax return positions and the benefits recognized in the Company’s financial statements, as of December 31, 2020, 2019, and 2018 of $2,297,000, $2,070,000, and $1,462,000, respectively, if recognized, may decrease the Company’s income tax provision and effective tax rate. None of the unrecognized tax benefits as of December 31, 2020, are expected to significantly change during the next twelve months. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits as a component of income tax expense. During the years ended December 31, 2020, 2019, and 2018, the Company recognized approximately $17,000, $7,000, and $7,000, respectively, in net interest expense. As of December 31, 2020 and 2019, the Company had accrued approximately $58,000 and $41,000, respectively, for the potential payment of interest. The Company files income tax returns in the United States and various foreign tax jurisdictions. These tax returns are generally open to examination by the relevant tax authorities from three to seven years from the date they are filed. The tax filings relating to the Company’s federal and state taxes are currently open to examination for tax years 2017 through 2019 and 2011 through 2019, respectively. In addition, the Company generated federal research and development credits in tax years 2005 through 2015. These years may also be subject to examination when the credits are carried forward and utilized in future years. There are no income tax examinations or audits currently in process. |

Commitments and Contingencies | 17. COMMITMENTS AND CONTINGENCIES The Company is the defendant in a patent infringement lawsuit originally filed on January 28, 2011 by SynQor, Inc. (“SynQor”) in the U.S. District Court for the Eastern District of Texas (the “Texas Action”). The complaint, as amended, alleges that the Company’s products, including but not limited to, unregulated bus converters used in intermediate bus architecture power supply systems, infringe SynQor’s U.S. patent numbers 7,072,190, 7,272,021, 7,564,702, and 8,023,290 (“the ‘190 patent”, “the ‘021 patent”, “the ‘702 patent”, and “the ‘290 patent”, respectively). SynQor’s complaint sought an injunction against further infringement and an award of unspecified compensatory and enhanced damages, interest, costs and attorney fees. The Company has denied that its products infringe any of the SynQor patents, and has asserted that the SynQor patents are invalid and/or unenforceable. The Company has also asserted counterclaims seeking damages from SynQor for deceptive trade practices and tortious interference with prospective economic advantage arising from SynQor’s attempted enforcement of its patents against the Company. On May 23, 2016, after extensive discovery, the Texas Action was stayed by the court pending completion of certain inter partes reexamination (“IPRx”) proceedings at the United States Patent and Trademark Office (“USPTO”) (including any appeals from such proceedings to the Federal Circuit (as defined below)) concerning the SynQor patents, which are described below. That stay remains in force. In 2011, in response to the filing of the Texas Action, the Company initiated IPRx proceedings at the USPTO challenging the validity of all claims that were asserted against the Company by SynQor. The current status of these proceedings is as follows. Regarding the ‘190 patent IPRx, the United States Court of Appeals for the Federal Circuit (the “Federal Circuit”) issued a decision on March 13, 2015, determining that certain claims were invalid and remanding the matter to the Patent Trial and Appeal Board (“PTAB”) of the USPTO for further proceedings. On February 20, 2019, the PTAB issued a decision finding that all of the remaining challenged claims were unpatentable. SynQor appealed that decision. On February 22, 2021, the Federal Circuit issued a decision in that appeal. In a 2-1 On August 30, 2017, the Federal Circuit issued rulings with regard to the IPRx proceedings for the ’021, ‘702 and ‘290 patents. With respect to the ‘021 patent, the Federal Circuit affirmed the PTAB’s determination that all of the challenged claims of the ‘021 patent were invalid. The Federal Circuit remanded the case to the PTAB for further consideration of the patentability of certain claims that had been added by amendment during the reexamination. On February 20, 2019, the PTAB issued a decision affirming the examiner’s rejections of all challenged claims. SynQor has filed an appeal of that decision in the Federal Circuit. That appeal has been stayed pending resolution of the pending appeal regarding the ‘190 patent IPRx. With respect to the ‘702 patent, the Federal Circuit affirmed the PTAB’s determination that all of the challenged claims of the ‘702 patent were patentable. With respect to the ‘290 patent, the Federal Circuit vacated the PTAB’s decision upholding the patentability of the ‘290 patent claims, and remanded the case to the PTAB for further consideration. On February 20, 2019, the PTAB issued a decision reversing its prior affirmance of the examiner’s non-adoption On October 31, 2017, the Company filed a request with the USPTO for ex parte reexamination (“EPRx”) of the asserted claims of the ‘702 patent, based on different prior art references than had been at issue in the previous IPRx of the ‘702 patent. On August 6, 2018, the Company filed a similar request with the USPTO for EPRx of the asserted claims of the ‘190 patent, based on different prior art references than had been at issue in the previous IPRx of the ‘190 patent. On December 18, 2020, the PTAB issued rulings upholding the validity of the asserted claims in the EPRx proceedings for both the ‘702 and ‘190 patents. Accordingly, both of those proceedings are now terminated. On January 23, 2018, the 20-year The Company continues to believe none of its products, including its unregulated bus converters, infringe any valid claim of the asserted SynQor patents, either alone or when used in an intermediate bus architecture implementation. The Company believes SynQor’s claims lack merit and, therefore, it continues to vigorously defend itself against SynQor’s patent infringement allegations. The Company does not believe a loss is probable for this matter. If a loss were to be incurred, however, the Company cannot estimate the amount of possible loss or range of possible loss at this time. In addition to the SynQor matter, the Company is involved in certain other litigation and claims incidental to the conduct of its business. While the outcome of lawsuits and claims against the Company cannot be predicted with certainty, management does not expect any current litigation or claims will have a material adverse impact on the Company’s financial position or results of operations. |

Accounting Policies [Abstract] | |
Principles of consolidation | Principles of consolidation The Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. |
Use of estimates | Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingencies at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such estimates and assumptions relate to the useful lives of fixed assets and identified intangible assets, recoverability of long-lived assets, fair value of short-term and long-term investments, allowances for doubtful accounts, potential excess, obsolete or unmarketable inventory, potential reserves relating to litigation matters, accrued liabilities, accrued taxes, deferred tax valuation allowances, assumptions pertaining to share-based payments, and other reserves. Actual results could differ from those based on these estimates and assumptions, and such differences may be material to the financial statements. |
Foreign currency translation | Foreign currency translation The financial statements of Vicor Japan Company, Ltd. (“VJCL”), a majority-owned subsidiary, for which the functional currency is the Japanese Yen, have been translated into U.S. Dollars using the exchange rate in effect at the balance sheet date for balance sheet amounts and the average exchange rates in effect during the year for income statement amounts. The gains and losses resulting from the changes in exchange rates from year to year have been reported in other comprehensive income. Transaction gains and losses resulting from the remeasurement of foreign currency denominated assets and liabilities of the Company’s foreign subsidiaries where the functional currency is the U.S. Dollar are included in other income (expense), net. Foreign currency gains (losses) included in other income (expense), net, were approximately $181,000, $(108,000), and $ ( 260,000) in 2020, 2019, and 2018, respectively. |
Investments | Investments The Company’s principal sources of liquidity are its existing balances of cash and cash equivalents and short-term investments, as well as cash generated from operations. Consistent with the guidelines of the Company’s investment policy, the Company can invest, and has historically invested, its cash balances in demand deposit accounts, money market funds, government debt securities, and auction rate securities meeting certain quality criteria. |
Cash and cash equivalents | Cash and Cash Equivalents Cash and cash equivalents are highly liquid investments with insignificant interest rate risk and maturities of 90 days or less at the time of acquisition. Cash and cash equivalents include funds held in disbursement (i.e., checking) and money market accounts, certificates of deposit, and debt securities with maturities of less than three months at the time of purchase. Cash and cash equivalents are valued at cost, approximating market value. The Company’s money market securities are purchased and redeemed at par value. Their estimated fair value is equal to their cost, and, due to the nature of the securities and their classification as cash equivalents, there are no unrealized gains or losses recorded at the balance sheet dates. |
Short-term Investments | Short-term Investments The Company’s short-term investments, consisting of obligations of the U.S. Treasury, are debt securities with original maturities greater than three months but less than one year the time of purchase. |
Long-term investments | Long-term Investment The Company’s long-term investment is an auction rate debt security with a maturity of greater than one year and is subject to credit, liquidity, market, and interest rate risk. |
Available-For-Sale Securities | Available-For-Sale Certain of the cash and cash equivalents, all of the short-term investments and the long-term investment are classified as available-for-sale non-credit The Company periodically evaluates the long-term investment to determine if impairment is required, whether an impairment is other than temporary, and the measurement of an impairment loss. The Company considers a variety of impairment indicators such as, but not limited to, a significant deterioration in the earnings performance, credit rating, or asset quality of the investment. The amortized cost of the debt securities are adjusted for amortization of premiums and accretion of discounts to maturity, the net amount of which, along with interest and realized gains and losses, is included in “Other income (expense), net” in the Consolidated Statements of Operations. |
Fair value measurements | Fair value measurements The Company accounts for certain financial assets at fair value, defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. A three-level hierarchy is used to show the extent and level of judgment used to estimate fair value measurements: Level 1 Inputs used to measure fair value are unadjusted quoted prices available in active markets for the identical assets or liabilities as of the reporting date. Level 2 Inputs used to measure fair value, other than quoted prices included in Level 1, are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in inactive markets. Level 2 also includes assets and liabilities valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument. Level 3 Inputs used to measure fair value are unobservable inputs supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The carrying amounts of cash and cash equivalents, short-term investments, accounts receivable, and accounts payable approximate fair value because of the short maturities of these financial instruments. |
Inventories | Inventories Inventories are valued at the lower of cost (determined using the first-in, first-out Inventory estimated to be excess, obsolete, or unmarketable is written down to net realizable value. The Company’s estimation process for assessing net realizable value is based upon management’s estimate of expected future utility which is derived based on backlog, historical consumption and expected market conditions. If the Company’s estimated demand and/or market expectations were to change or if product sales were to decline, the Company’s estimation process may cause larger inventory reserves to be recorded, resulting in larger charges to cost of revenues. |
Concentrations of risk | Concentrations of risk Financial instruments potentially subjecting the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and short-term investments, of which a significant portion are held by three financial institutions, its long-term investment, and trade accounts receivable. The Company maintains cash and cash equivalents, short-term investments and certain other financial instruments with high credit counterparties, and continuously monitors the amount of credit exposure to any one issuer and diversifies its investments in order to minimize its credit risk. Generally, amounts invested with these financial institutions are in excess of federal deposit insurance limits. The Company has not experienced any losses in such accounts, and management believes the Company is not exposed to significant credit risk. The Company’s long-term investment as of December 31, 2020 consists of a single auction rate security with a par value of $3,000,000, which is collateralized by student loans. It is a highly rated (Aaa/AA+) municipal and corporate debt security. Through December 31, 2020, auctions held for the Company’s auction rate security have failed. The funds associated with an auction rate security that has failed auction may not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the security is called, or the underlying securities have matured. If the credit rating of the issuer of the auction rate security held deteriorates, the Company may be required to adjust the carrying value of the investment for an other-than-temporary decline in value through an impairment charge. The Company’s investment policy, approved by the Board of Directors, limits the amount the Company may invest in any issuer, thereby reducing credit risk concentrations. The Company’s products are sold worldwide to customers ranging from smaller, independent manufacturers of highly specialized electronic devices, to larger OEMs, ODMs and their contract manufacturers. See Note 19, Segment Information , for a discussion of a change to segment reporting in the second quarter of 2019. The Company’s Brick Products’ customers are primarily concentrated in the following industries: aerospace and defense electronics, industrial automation, industrial equipment, instrumentation and test equipment, and transportation (notably in rail and heavy equipment applications). The Company’s Advanced Products’ customers are concentrated in the data center and hyperscaler segments of enterprise computing, in which the Company’s products are used for voltage distribution on server motherboards, in server racks, and across datacenter infrastructure The Company also targets applications in aerospace and aviation, defense electronics, industrial automation, instrumentation, test equipment, solid state lighting, telecommunications and networking infrastructure, and vehicles (notably in the autonomous driving, electric vehicle, and hybrid vehicle niches of the vehicle segment). While, overall, the Company has a broad customer base and sells into a variety of industries, a substantial portion of the Company’s revenue from its Advanced Products line has been derived from a limited number of customers. This concentration of revenue is a reflection of the relatively early stage of adoption of the technologies, architectures and products offered in the Advanced Products line, and the Company’s strategy of targeting market leading innovators as initial customers for its Advanced Products. Concentrations of credit risk with respect to trade accounts receivable are limited due to the number of entities comprising the Company’s customer base. As of December , and , customer accounted for approximately % and %, respectively, of trade account receivables. Components and materials used in the Company’s products are purchased from a variety of vendors. While most of the components are available from multiple sources, some key components for certain Advanced Products, in particular, are supplied by single vendors. In instances of single source items, the Company maintains levels of inventories management considers appropriate to enable meeting the delivery requirements of customers. If suppliers or subcontractors cannot provide their products or services on time or to the required specifications, the Company may not be able to meet the demand for its products and its delivery times may be negatively affected. |
Long-lived assets | Long-lived assets The Company reviews property, plant and equipment and finite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying value of such assets may not be recoverable. Management determines whether the carrying value of an asset or asset group is recoverable based on comparison to the undiscounted expected future cash flows the assets are expected to generate over their remaining economic lives. If an asset value is not recoverable, the impairment loss is equal to the amount by which the carrying value of the asset exceeds its fair value, which is determined by either a quoted market price, if any, or a value determined by utilizing a discounted cash flow technique. Evaluation of impairment of long-lived assets requires estimates of future operating results that are used in the preparation of the expected future undiscounted cash flows. Actual future operating results and the remaining economic lives of our long-lived assets could differ from the estimates used in assessing the recoverability of these assets. These differences could result in impairment charges, which could be material. |
Intangible assets | Intangible assets Values assigned to patents are amortized using the straight-line method over periods ranging from three to years. Patents and other intangible assets are included in “Other assets” in the accompanying Consolidated Balance Sheets. |
Product warranties | Product warranties The Company generally offers a two-year |
Revenue recognition | Revenue recognition Revenue is recognized when control of the promised goods or services is transferred to a customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Sales, value add, and other taxes collected concurrent with revenue producing activities are excluded from revenue. The expected costs associated with product warranties continue to be recognized at the time product revenue is recognized. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of revenues. The Company’s primary source of net revenue comes from the sale of products, which are modular power components and power systems for converting, regulating and controlling electric current. The principal customers for the Company’s power converters and systems are large OEMs, ODMs and the original design manufacturers and contract manufacturers serving them, and smaller, lower volume users, which are broadly distributed across several major market areas. The Company recognizes revenue for product sales at a point in time following the transfer of control of such products to the customer, including sales to stocking distributors, which typically occurs upon shipment or delivery, depending on the terms of the underlying contract. The Company establishes sales allowances on shipments to stocking distributors for estimated future product returns including distributor returns and price adjustment credits, primarily based upon historical and anticipated rates of product returns and allowances. Certain contracts with customers contain multiple performance obligations, which typically may include a combination of non-recurring production units represent a separate distinct performance obligation. For such arrangements, revenue is allocated to each performance obligation based on its relative standalone selling price, based on prices charged to customers or using the expected cost plus a margin approach. The Company delays revenue recognition for NRE and prototype units until the point in time at which the final milestone under the NRE arrangement is completed and control is transferred to the customer, which is generally the shipment or delivery of the prototype. Revenue for production units is recognized upon shipment or delivery, consistent with product revenue summarized above . The Company licenses its intellectual property under right to use licenses, in which royalties due to the Company are based upon a percentage of the licensee’s sales. The Company utilizes the exception under the revenue recognition guidance for the recognition of sales- or usage-based royalties, in which the royalties are not recognized until the later of when 1) the customer’s subsequent sales or usages occur, or 2) the performance obligation to which some or all of the sales- or usage-based royalty has been allocated is satisfied or partially satisfied. Accounts receivable includes amounts billed and currently due from customers. The amounts due are stated at their estimated realizable value. The Company’s payment terms vary by the type and location of its customers and the products or services offered, although terms generally include a requirement of payment within 30 to 60 days. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, based on assessments of customers’ credit-risk profiles and payment histories. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company does not require collateral from its customers, although there have been circumstances when the Company has required cash in advance (i.e., a partial down-payment) to facilitate orders in excess of a customer’s established credit limit. To date, such amounts have not been material. The Company records deferred revenue, which represents a contract liability, when cash payments are received or due in advance of performance under a contract with a customer. During the years ended December 31, 2020 and 2019, the Company recognized revenue of approximately $3,550,000 and $76,000, respectively, that was included in deferred revenue at the beginning of the respective period. The Company applies the practical expedient for the incremental costs of obtaining a contract for sales commissions, which are expensed when incurred because the amortization period is generally less than one year. These costs are included in selling, general and administrative expenses. The Company also applies another practical expedient and does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. |
Advertising expense | Advertising expense The cost of advertising is expensed as incurred. The Company incurred approximately $2,637,000, $2,749,000, and $2,610,000 in advertising costs during 2020, 2019, and 2018, respectively. |
Legal Costs | Legal Costs Legal costs in connection with litigation are expensed as incurred. |
Stock-based compensation | Stock-based compensation The Company uses the Black-Scholes option-pricing model to calculate the fair value of stock option awards, whether they possess time-based vesting provisions or performance-based vesting provisions, and awards granted under the Vicor Corporation 2017 Employee Stock Purchase Plan (“ESPP”), as of their grant date. For stock options with time-based vesting provisions, the calculated compensation expense, net of expected forfeitures, is recognized on a straight-line basis over the service period of the award, which is generally five years for stock options. For stock options with performance-based vesting provisions, recognition of compensation expense, net of expected forfeitures, commences if and when the achievement of the performance criteria is deemed probable. For stock options with performance-based vesting provisions, compensation expense, net of expected forfeitures, when recognized, is recognized over the relevant performance period. |
Income taxes | Income taxes Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted income tax rates and laws expected to be in effect when the temporary differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if management determines it is more likely than not that some portion or all of the deferred tax assets will not be realized. All deferred tax assets and liabilities are classified as noncurrent. The Company follows a two-step “more-likely-than-not” “more-likely-than-not” |
Net income (loss) per common share | Net income per common share The Company computes basic net income per share using the weighted average number of common shares outstanding and diluted net income per share using the weighted average number of common shares outstanding plus the effect of outstanding dilutive stock options, if any. The following table sets forth the computation of basic and diluted net income per share for the years ended December 31 (in thousands, except per share amounts): 2020 2019 2018 Numerator: Net income attributable to Vicor Corporation $ 17,910 $ 14,098 $ 31,725 Denominator: Denominator for basic net income per share-weighted average shares (1) 42,186 40,330 39,872 Effect of dilutive securities: Employee stock options (2) 1,683 1,347 857 Denominator for diluted net income per share-adjusted weighted-average shares and assumed conversions (3) 43,869 41,677 40,729 Basic net income per share $ 0.42 $ 0.35 $ 0.80 Diluted net income per share $ 0.41 $ 0.34 $ 0.78 (1) Denominator represents weighted average number of Common Shares and Class B Common Shares outstanding. (2) Options to purchase 181,196, 164,367 and 67,247 shares of Common Stock in 2020, 2019, and 2018, respectively, were not included in the calculation of net income per share as the effect would have been antidilutive. (3) Denominator represents weighted average number of Common Shares and Class B Common Shares outstanding for the year, adjusted to include the dilutive effect, if any, of outstanding options. |
Comprehensive income (loss) | Comprehensive income (loss) The components of comprehensive income (loss) include, in addition to consolidated net income (loss), unrealized gains and losses on investments, net of tax and foreign currency translation adjustments related to VJCL, net of tax. |
Impact of recently issued accounting standards | Impact of recently issued accounting standards In December 2019, the FASB issued guidance designed to simplify the accounting for income taxes by eliminating certain exceptions to the general principles in Topic 740, Income Taxes In August 2018, the FASB issued guidance which modifies the disclosure requirements on fair value measurements under Topic 820, Fair Value Measurements, including the consideration of costs and benefits. The new guidance is effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2019, with early adoption permitted. It is required to be applied on a retrospective approach with certain elements being adopted prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. The Company adopted the new guidance as of January 1, 2020. The adoption did not have a material impact on the Company’s consolidated financial statements and disclosures. In June 2016, the FASB issued new guidance which will require measurement and recognition of expected credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale Other new pronouncements issued but not effective until after December 31, 2020 are not expected to have a material impact on the Company’s consolidated financial statements. |
