PWM Chopper of Ultrasonic Power Supply Based on FPGA

Abstract:

Pulse width modulation (PWM) is often one of the important power regulation method of ultrasonic power supply. The traditional PWM control circuit has the shortcomings of complex design structure, slow dynamic response and low reliability. An advanced PWM technique for choppers of ultrasonic power supply based on FPGA is proposed. Through open-loop operation, it regulates the output pulse width of ultrasonic power supply dynamically. The simulation result shows that the PWM control circuit based on FPGA can realize to adjust the width of PWM signal and power regulation conveniently.
