摘要

为改善单相全桥逆变器的效率，提出了一种新型高效率单相全桥零电流开关谐振极逆变器拓扑结构.在桥臂上的辅助谐振电路参与换流的过程中，逆变器的开关器件可实现零电流软关断.当开关器件为绝缘栅双极型晶体管（Insulated Gate Bipolar Transistor，IGBT）时，IGBT实现零电流软关断可使其拖尾电流导致的关断损耗等于零，有利于改善以IGBT作为开关器件的单相全桥逆变器的效率.分析了电路工作流程.实验结果显示出开关器件完成了零电流软切换动作.因此，对于研发以IGBT作为开关器件的高效率单相全桥逆变器，该拓扑结构具有一定的参考价值.

Abstract

In order to improve the efficiency of single-phase full-bridge inverter

a topology of high efficiency single-phase full-bridge zero-current switching resonant pole inverter is proposed. When the auxiliary resonant circuit on the bridge arm works in commutation process of the inverter

the switching devices of the inverter can realize zero-current turn-off. When the switching device is insulated gate bipolar transistor (Insulated Gate Bipolar Transistor

IGBT)

zero-current turn-off of IGBT can make the turn-off loss caused by trailing current be equal to zero

which is beneficial to improving the efficiency of single-phase full-bridge inverter with IGBT as switching devices. The working process of the circuit is studied. The experimental results show that the switching devices realize zero-current soft-switching. Therefore

the topology has certain reference value for the research and development of high efficiency single-phase full-bridge inverter with IGBT as switching device.
