Abstract

This paper presents a novel prototype version of ZCS-PWM forward DC-DC power converter using power MOSFETs which is designed for application specific low voltage large current conversion operation. The soft-switching forward power converter with a high frequency isolated transformer link which can efficiency operate over wide load ranges under two conditions of ZCS as well as active voltage clamped switching is evaluated and discussed on the basis of the simulation and experimental results.
