Title :
A New Method to Realize ZVS-PWM in Full Load Range (A)
Abstract :
A current-stable power supply (Io=300 A, Vo=30 V) for wiggler magnet on the basis of ZVS converter and frequency-fixed PWM technology is designed. This power supply has realized ZVS-PWM in full load scope with this new method. In this way, we can greatly reduce the noise emission and power loss, and improve the reliability of the power supply obviously. This paper discusses the new method and analyzes the working process of the converter in great detail
