摘要

作为中小功率发电系统重要环节的三相逆变器的开关频率增大时，开关损耗也显著增大，不利于节能。为实现中小功率三相逆变器的高频化和节能化，提出了一种三相零电压开关谐振极逆变器拓扑结构.当桥臂上的辅助谐振电路处于工作状态时，开关器件并联的电容的电压能周期性变化到零，使开关器件完成零电压软切换，这有利于高频金属氧化物半导体场效应晶体管（Metal Oxide Semiconductor Field Effect Transistor，MOSFET）作为逆变器的开关器件.分析了电路的工作流程，实验结果表明开关器件处于零电压软切换.因此，该拓扑结构对于研发高性能的中小功率三相逆变器具有参考价值.

Abstract

When the switching frequency of the three-phase inverter used as an important link in the medium and small power generation system increases

switching loss will also increase significantly

which is not favourable to save energy.In order to realize high frequency and energy-saving of medium and small power three-phase inverter

a topology of three-phase zero-voltage switching resonant pole inverter is proposed.When the auxiliary resonant circuit on the bridge arm is in a working state

the voltage across the capacitors parallel with the main switches and the auxiliary switches can periodically change to zero

so that the switching devices can achieve zero-voltage soft-switching

which is beneficial to the metal oxide semiconductor field effect transistor (MOSFET) used as the switching device of the inverter.The working flow of the circuit is analyzed.The experimental results show that the switching devices achieve zero-voltage soft-switching.Therefore

this topology structure has certain reference value for the research and development of the small and medium power three-phase inverter with high-performance.
