ADVANCED ENERGY INDUSTRIES, INC.

PROXY STATEMENT FOR 1997 ANNUAL MEETING OF STOCKHOLDERS

INFORMATION CONCERNING SOLICITATION AND VOTING

GENERAL

The enclosed proxy is solicited on behalf of Advanced Energy Industries,
Inc., a Delaware corporation (the "Company"), for use at the Annual Meeting of
Stockholders (the "Annual Meeting") to be held on Thursday, May 15, 1997, at
10:00 a.m., local time, or at any adjournment thereof, for the purposes set
forth herein and in the accompanying Notice of Annual Meeting Of Stockholders.
The Annual Meeting will be held at the Company's executive offices at 1625 Sharp
Point Drive, Fort Collins, Colorado 80525. The Company's telephone number is
(970) 221-4670.

These proxy solicitation materials were mailed on or about April 9, 1997 to
all stockholders entitled to vote at the meeting. A copy of the Company's 1996
Annual Report to Stockholders accompanies this Proxy Statement.

RECORD DATE AND PRINCIPAL SHARE OWNERSHIP

Stockholders of record at the close of business on March 31, 1997 (the
"Record Date") are entitled to receive notice of and to vote at the Annual
Meeting. On the Record Date, 21,277,495 shares of the Company's Common Stock,
$0.001 par value (the "Common Stock"), were issued and outstanding.

REVOCABILITY OF PROXIES

Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before its use by delivering to the Company a written
notice of revocation or a duly executed proxy bearing a later date or by
attending the Annual Meeting and voting in person. Attending the Annual Meeting
in and of itself may not constitute a revocation of a proxy.

VOTING AND SOLICITATION

Each share of Common Stock entitles its holder to one vote on matters to be
acted upon at the Annual Meeting. Votes cast by proxy or in person at the Annual
Meeting will be tabulated by the Inspector of Elections (the "Inspector") with
the assistance of the Company's transfer agent. The Inspector will also
determine whether or not a quorum is present. The affirmative vote of a majority
of shares present in person or represented by proxy at a duly held meeting at
which a quorum is present is required under Delaware law for approval of
proposals presented to stockholders. In general, Delaware law also provides that
a quorum consists of a majority of the shares entitled to vote and present or
represented by proxy at the meeting. The Inspector will treat abstentions as
shares that are present and entitled to vote for purposes of determining the
presence of a quorum but will not treat abstentions as votes in favor of
approving any matter submitted to the stockholders for a vote. Any proxy which
is returned using the form of proxy enclosed and which is not marked as to a
particular item will be voted for the election of directors, for ratification of
the appointment of the designated independent auditors and, as the case may be
with respect to any items not marked, as the proxy holders deem advisable, on
the other matters that may come before the meeting. If a broker indicates on the
enclosed proxy or its substitute that it does not have discretionary authority
as to certain shares to vote on a particular matter ("broker non-votes"), those
shares will not be considered as present with respect to that matter. The
Company believes that the tabulation procedures to be followed by the Inspector
are consistent with the general statutory requirements in Delaware concerning
voting of shares and determination of a quorum.

The cost of soliciting proxies will be borne by the Company. The Company has
retained the services of the Bank of Boston c/o Boston Equiserve to aid in the
solicitation of proxies from bankers, bank nominees and other institutional
owners. The Company estimates that it will pay the Bank of Boston a fee not to
exceed $2,500 for its services and will reimburse the Bank of Boston for certain
out-of-pocket expenses. The Company may reimburse brokerage firms and other
persons representing beneficial owners of shares for their expenses in
forwarding solicitation materials to such beneficial owners. Proxies may also be
solicited by certain of the Company's directors, officers and regular employees,
without additional compensation, personally or by telephone, telefax, or
telegram.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The members of the Compensation Committee during the fiscal year ended
December 31, 1996 were Elwood Spedden and Jon Tompkins. Neither of such persons
is or has been an officer or employee of the

Company or any of its subsidiaries, nor has either of such persons had a direct
or indirect interest in any business transaction with the Company which involved
an amount in excess of $60,000. None of the executive officers of the Company
has served as a member of the board of directors or on the compensation
committee of any other company of which any member of the Compensation Committee
is or has been an executive officer.

REPORT ON EXECUTIVE COMPENSATION

The Compensation Committee, which consists of two non-employee directors,
reviews and makes recommendations with respect to the Company's executive
compensation policies and the compensation to be paid to each of the executive
officers. The recommendations of the Compensation Committee with respect to each
executive officers' compensation are subject to approval by the Board of
Directors.

COMPENSATION POLICIES

One of the primary goals in setting compensation policies is to maintain
competitive, progressive programs to attract, retain and motivate high caliber
executives, foster teamwork and maximize the long-term success of the Company by
appropriately rewarding such individuals for their achievements. Another goal is
to provide an incentive to executives to focus efforts on long-term strategic
goals for the Company by closely aligning their financial interests with
stockholder interests. To attain these goals the Company's executive
compensation program was designed to include base salary, annual incentives and
long-term incentives.

In formulating and administering the individual elements of the Company's
executive compensation program, planning, implementing and achieving long-term
objectives are emphasized to establish performance objectives, evaluate
performance and determine actual incentive awards.

Following these policies the Company has been able to attract and retain the
executive talent necessary to support a corporation which has increased its
revenues by more than 300 percent over the last four years.

COMPENSATION COMPONENTS

BASE SALARY The base salaries of executive officers were established after
review of relevant data of other executives with similar responsibilities from
published industry reports and surveys of similarly situated companies. The
objective is to maintain the Company's annual executive salaries at levels
competitive with the market average base salary of executive officers in similar
positions. The market is comprised of similarly sized high technology companies
within and outside the Company's industry. In 1997, a larger portion of each
executive officer's compensation will be in the form of a cash bonus, provided
certain target performance objectives are met. The Compensation Committee has
established base salary and incentives for the executive officers for 1997.

ANNUAL INCENTIVES The more aggressive incentive bonus levels for executives
are intended to provide the appropriate elements of variability and risk. Bonus
payments are tied specifically to targeted corporate performance. The Committee
will establish a base bonus amount, determined through review of a competitive
market survey for executives at similar levels, which will be incrementally
reduced if the Company does not meet its targeted performance or increased if
the Company exceeds its targeted performance. There is no minimum or maximum
percentage by which the bonus can be reduced or increased.

STOCK OPTIONS The Committee will grant stock options under the Company's
Stock Option Plan to focus the executive's attention on the long-term
performance of the Company and on maximizing stockholder value. The grant of
stock options is closely tied to individual executive performance. The Committee
will grant such stock options after a review of various factors, including the
executive's potential contributions to the Company, current equity ownership in
the Company and vesting rates of existing stock options, if any. Incentive stock
options and nonstatutory stock options are granted with an exercise price of at
least 100% and 85%, respectively, of the fair market value of the Common Stock
subject to the option on the date of the grant and utilize vesting periods to
encourage retention of executive officers. Because of the direct benefit
executive officers receive through improved stock performance, the Committee
believes stock options serve to align the interests of executive officers
closely with those of other stockholders.

COMPENSATION OF CHIEF EXECUTIVE OFFICER

The compensation of the Chief Executive Officer, Mr. Douglas S. Schatz, was
based on the policies and procedures described above. In determining Mr.
Schatz's base salary and bonus, compensation levels for other chief executive
officers in high technology firms within and outside the industry were examined.
This information was compared to the relevant performance of such firms relative
to the Company's performance.

EFFECT OF SECTION 162(M) OF THE INTERNAL REVENUE CODE

Section 162(m) of the Internal Revenue Code of 1986 (the "Code") generally
limits the corporate deduction for compensation paid to certain executive
officers to $1 million, unless the compensation is performance based. The Board
has carefully considered the potential impact of this tax code provision on the
Company and has concluded in general that the best interests of the Company and
the stockholders will be served if certain of the Company's stock-based
long-term incentives qualify as performance-based compensation within the
meaning of the Code. It is the Board's intention that, so long as it is
consistent with its overall compensation objectives, virtually all executive
compensation will be deductible for federal income tax purposes.

CERTAIN TRANSACTIONS

The Company's executive offices and manufacturing facilities in Fort
Collins, Colorado are leased from Sharp Point Properties, LLP, a Colorado
limited liability (the "LLP"), in which Douglas S. Schatz, President, Chief
Executive Officer and Chairman of the Board of the Company, and G. Brent
Backman, Vice President, Special Projects of the Company, hold 26.67% and 6.66%
member interests, respectively. The Company believes that the terms of such
leases are no less favorable than could have been obtained from a third party
lessor. Aggregate rental payments under such leases for 1996 totaled
approximately $750,420. In May 1995, the Company entered into a new lease, also
with the LLP, for a building constructed adjacent to the Company's executive
offices in connection with the Company's expansion. Annual rental payments under
the new lease are approximately $552,513. In addition, the Company paid
approximately $1.3 million for leasehold improvements under this lease. The
Company believes that the terms of the new lease are no less favorable than
could have been obtained from a third party lessor.

The Company leases a condominium in Breckenridge, Colorado owned by a
partnership formed by Messrs. Schatz and Backman. The Company uses the
condominium to provide rewards and incentives to its customers, suppliers and
employees. The Company believes that the terms of such lease are no less

favorable than could have been obtained from a third party lessor. Aggregate
rental payments under such lease for 1996 totaled $36,000.

PROPOSAL NO. 2
RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

Unless marked to the contrary, proxies received will be voted "FOR" the
ratification of the appointment of Arthur Andersen LLP as the independent
auditors for the Company for the current year. Arthur Andersen LLP has been the
Company's independent auditors since 1994. If the stockholders fail to ratify
the appointment of Arthur Andersen LLP, the Board of Directors will reconsider
its selection.

Audit services of Arthur Andersen LLP during the 1996 fiscal year included
the examination of the consolidated financial statements of the Company and
services related to filings with the Securities and Exchange Commission ("SEC")
and other regulatory bodies.

The Audit Committee of the Company will meet with Arthur Andersen LLP on an
annual or more frequent basis. At such time the Audit Committee will review the
services performed by Arthur Andersen LLP for the preceding year, as well as the
fees charged for such services.

A representative of Arthur Andersen LLP is expected to be present at the
Annual Meeting and will have an opportunity to make a statement if he or she so
desires. Moreover, the representative is expected to be available to respond to
appropriate questions from the stockholders.

THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS A VOTE "FOR" THE
RATIFICATION OF THE APPOINTMENT OF ARTHUR ANDERSEN LLP AS INDEPENDENT AUDITORS.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act requires the Company's
executive officers and directors and persons who own more than ten percent of a
registered class of the Company's equity securities to file an initial report of
ownership on Form 3 and changes in ownership on Form 4 or 5 with the SEC.
Executive officers, directors and greater than ten percent stockholders are also
required by SEC rules to furnish the Company with copies of all Section 16(a)
forms they file. Based solely on its review of the copies of such forms received
by it, or written representations form certain reporting persons, the Company
believes that during the last fiscal year, all Section 16(a) filing requirements
applicable to its officers, directors and ten percent stockholders were complied
with.
