Abstract :
This paper proposes a novel zero-current-transition (ZCT) PWM full bridge DC/DC converter. The proposed converter not only achieves ZCS for the main switches and auxiliary switch in the entire load ranges but also realizes soft commutation for the output rectifier diodes. Furthermore, the auxiliary circuit also helps softly turn on the main switches. Simulation results and experimental results verify the theoretical analysis
