本文提出了一种具有零电压开关（ZVS）功能的非隔离升压变换器的新拓扑。为了实现ZVS条件，辅助电路仅由一个耦合电感和一个二极管组成，其工作在零电流开关（ZCS）条件下。由于零电压开关，MOSFET反并联体二极管的反向恢复问题可以得到解决，并降低了开关元件上的电压和电流应力。文中给出了该变换器的工作原理和主电路的设计方法。为了验证该升压变换器的有效性和可行性，搭建了一台500 W的实验样机，给出了相关的实验波形和效率曲线。
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.
