Utility
Cancellation of the Effects of Primary Voltage Variations
5 Oct 23
A method for cancelling the effects of variation of primary voltage supplied to a welding power supply includes receiving a mains voltage at the welding power supply, rectifying the mains voltage to obtain a rectified voltage, applying the rectified voltage to an input of a pulse wave modulated (PWM) controlled inverter, detecting a value of the rectified voltage, setting a maximum duty cycle for the PWM controlled inverter based on the value of the rectified voltage, and operating the PWM controlled inverter in accordance with the maximum duty cycle for the PWM controlled inverter.
