摘要

为实现三相逆变器的高效率运行，提出了一种新型三相谐振直流环节逆变器拓扑结构，其在直流环节设置了结构简单的辅助谐振电路.分析了电路的工作流程.实验结果表明开关器件实现了软切换，而且逆变器输出电流波形无明显畸变.因此，该逆变器能实现高效率稳定运行.

Abstract

In order to achieve high efficiency operation of three-phase inverter

a novel topology of the three-phase resonant DC(Direct Current) link inverter is proposed

in which a simple auxiliary resonant circuit is set up in the DC link. The working flow of the circuit is analyzed. The experimental results show that the switching device achieves soft switching and the output current waveform of the inverter has no obvious distortion Therefore

the inverter can realize high-efficiency and stable operation.
