Abstract :
A new ZVCS resonant DC/DC converter is presented in which the resonant circuit is located at the secondary side of the transformer and using the secondary leakage inductance as the resonant inductor. The proposed converter topology is suitable for unregulated low-voltage to high-voltage power conversion, as in battery-powered systems. The MOSFET primary switches and the output rectifiers turn-on and turn-off operate under zero-voltage and zero-current switching conditions. The measured efficiency is more than 94.5% from 20% loaded to full loaded
