摘要

为改善以绝缘栅双极型晶体管（Insulated Gate Bipolar Transistor，IGBT）作为开关器件的单相全桥逆变器的效率，提出了一种节能型单相全桥零电流开关谐振极逆变器，在每个桥臂上分别并联1组辅助电路.在工作过程中，主开关和辅助开关都能完成零电流软切换，可消除IGBT拖尾电流造成的关断损耗.分析了电路工作过程，在2kW样机上的实验结果表明开关器件实现了零电流软切换.因此，该拓扑结构可实现以IGBT作为开关器件的单相全桥逆变器的节能运行.

Abstract

In order to improve the efficiency of single-phase full-bridge inverter with insulated gate bipolar transistor (IGBT) as switching devices

a energy-saving single-phase full-bridge zero-current switching resonant pole inverter is proposed. A set of auxiliary circuit is connected with parallel on each bridge arm. In the working process

both the main switches and the auxiliary switches can achieve zero-current soft-switching

which can eliminate the turn-off loss caused by the tail current of IGBT. The working process of the circuit is analyzed. The experimental results on the 2kW prototype show that the switching devices achieve zero-current soft-switching. Therefore

the topology can realize the energy-saving operation of the single-phase full-bridge inverter with IGBT as the switch devices.
