A Novel ZVS Bidirectional DC-DC Converter for Fuel Cell Applications

A. Salami and E. Rezaei
Abstract—In this paper a new bidirectional dc-dc converter for a fuel cell system is proposed that has a current tripler rectifier in its low voltage side. The converter is based on a ZVS half bridge topology with current tripler rectifier at the secondary side of transformer. The asymmetrical PWM is used in the converter to achieve ZVS of power switches and to regulate the output voltage at the desired value. The proposed converter has the advantages of high efficiency, high power density and simple circuit configuration. The operation principle and system analysis are described and discussed. Finally, the simulation results for the proposed converter are provided to verify the theoretical analysis.

Index Terms—Bidirectional dc-dc converter, current tripler rectification, fuel cell, zero voltage switching.
