摘要：
In this paper, a new topology of a nonisolated boost converter with zero-voltage-switching (ZVS) capabilities is proposed. In order to realize ZVS conditions, the auxiliary circuit only consists of a coupled inductor and a diode, which operates with a zero-current-switching (ZCS) condition. Due to ZVS, the reverse recovery problem of MOSFET antiparallel body diodes can be resolved, and the voltage and current stresses on the switch components are also reduced. The detailed operating analysis of the proposed converter and the design method of the main circuit are presented. With the aim to verify the effectiveness and feasibility of the proposed boost converter, a 500 W experimental prototype is built up, and the related experimental waveforms and the efficiency curve are presented.
