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.

Key words: inverter, bridge arm, high-efficiency, resonance, zero-current switch, tail current
