Abstract

A new high efficiency DC/DC converter is proposed, which is derived from the conventional half-bridge converter. The proposed converter has good ZVS condition compared with the conventional half-bridge converter, and shows a high efficiency by solving the unbalance voltage stress and current stress problem of secondary rectifier diode of the conventional half-bridge converter. In this paper, the basic operations of the proposed converter is analyzed compared with that of the conventional half-bridge converter, and the excellent performance of the proposed converter is verified by the experimental results with the 42W prototype of the power supply for PDP Sustain Driver.
