Development of Power Conditioning System for fuel cell system adopts the high efficient DC-DC conversion technology

Abstract

A novel zero current switching (ZCS) dual full bridge dc-dc converter and power conditioning system (PCS) for fuel cell system adopts the proposed dc-dc converter are presented. An experimental implementation shows the efficiency of the proposed converter higher than 98% at maximum. Prototypes of PCS also obtained high conversion efficiency at low voltage and high current dc input operation of fuel cell.
