Abstract :
In this paper, a new quasi-resonant PWM converter is proposed. The operational modes of the converter are analyzed. This converter achieves zero-voltage switching for both main and auxiliary switching devices, and the blocking voltages of the switches clamp at an acceptable level when the switches are turned off. The application of the converter in power factor correction is developed. A prototype is constructed for verification
