Abstract :
This paper deals with a power efficiency improvement of the full bridge current resonant DC-DC converter, which is developed to be applied to the power conditioner of the fuel cell generation system. The loss by the backward current of the side rectification diode can be decreased with a voltage doubler rectifier. The center tap rectifier is used for the conventional full bridge current resonant converter. The recovery loss of the rectifier diode can be decreased by using the voltage doubler rectifier. The maximum power efficiency of the proposed DC-DC converters is 97.4%.
