摘要

提出了一种适用于三相逆变器的零电压转换(ZVT)拓扑。该拓扑仅包含两个辅助开关，可以实现主开关的零电压导通和辅助开关的零电流关断。引入改进的空间矢量调制(SVM)，使零电压导通在任何开关条件下都成为可能。仿真和试验结果表明，与硬开关和传统双开关三相逆变器相比，该方法改善了开关特性，降低了开关损耗。

A novel ZVT three-phase inverter with coupled inductors

This paper proposes a novel zero-voltage transition (ZVT) topology applied to a three-phase inverter. This topology, including only two auxiliary switches, can achieve the zero-voltage turn-on of main switches as well as the zero-current turn-off of auxiliary switches. The modified space-vector modulation (SVM) is introduced to make the zero voltage turn-on possible in any switching condition. The simulation and test results show the improved switching characteristics and the reduced losses compared to the hard-switching and the conventional ZVT with two switches in three-phase inverters.
