A new soft switched push pull current fed converter for fuel cell applications

Abstract In this paper a new zero voltage switching current fed push pull dc–dc converter is proposed for fuel cell generation system. The auxiliary circuit in this converter, not only absorbs the voltage surge across the switches at turn off instance, but also provides zero voltage switching condition for all converter switches. Therefore, the converter efficiency is increased and size and weight of the converter can be decreased. Also implementation of control circuit is very simple since the converter is PWM controlled. In this paper, the proposed dc–dc converter operating modes are analyzed and to verify the converter operation a laboratory prototype is implemented and the experimental results are presented.
