Abstract

A new half bridge converter with parallel-series connected four-transformer is proposed for an electric vehicle charger with wide range zero voltage switching operation. The proposed converter combines two sets of two-transformer half bridge converter as a parallel-series connection to accommodate an auxiliary battery charger in an automotive application. The circuit configuration and principles of operation are analyzed in detail and design equations are presented. To verify advantages of the proposed converter, 1.2 kW hardware prototype is built.
