摘要：

In this paper, a new converter with two variations is proposed, A novel asymmetrical pulse-width-modulation (PWM) control scheme is used to control the converter under constant switching frequency operation, The modes of operation for both variations are discussed, The de characteristics, which can be used in the design of the converters, are also presented, Two 50-W converters were built to verify the characteristics of the converters, Due to the zero-voltage-switching (ZVS) operation of the switches and low device voltage and current stresses, the converter has high full-and partial-load efficiencies. They are potential candidates for high-efficiency high density power supplies application.
