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