A new high efficiency DC/DC converter is proposed, which is derived from the conventional asymmetric half-bridge converter. Because the proposed converter has better ZVS condition compared with the conventional asymmetric half-bridge converter, it shows a high efficiency along the wide load range. In this paper, the basic operations of the proposed converter is analyzed and 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 425W, 385-170Vdc prototype of the power supply for PDP (Plasma Display Panel) Sustain Driver of PDP TV.
