Abstract :
A two phase ZVS full-bridge converter with a novel hybrid current doubler rectifier structure is proposed in this paper. With the proposed topology, the secondary windings of the transformers work in series when the input voltage is low but in parallel when the input voltage is high. The diode stress on the second winding is reduced and the interleaving operation reduces the current ripple in the output filter. It can be employed in low voltage high current ouput and high power applications. A prototype with 200-400V input and 50V/20A output is built up to verify the theoretical analysis.
