Abstract :
This paper presents a novel ZVS PWM DC/DC power converter for high power applications. By using two active switches on the secondary side of a transformer, the proposed converter achieves not only ZVS of the active switches in the entire load range, but also soft commutation of the output rectifier diodes. Simulation results and experimental results of a 2.8 kW 200 kHz DC/DC converter are presented
