摘要

为改善单相AC-DC-AC变换器的性能，提出了一种单相谐振直流环节零电压开关AC-DC-AC功率变换器拓扑结构，由图腾柱式单相整流器，位于直流环节的辅助谐振电路和单相全桥逆变器组成.利用同一组辅助电路能分别将整流器输出端电压和逆变器输入端电压变化到零，使整流器和逆变器桥臂上的开关器件分别实现零电压切换.分析了电路的工作流程，在1.2kW样机上的实验结果表明开关器件完成了软切换.该拓扑结构对于研发节能型单相AC-DC-AC变换器具有借鉴意义.

Abstract

In order to improve the performance of the single-phase AC-DC-AC converter

a single-phase resonant DC link zero-voltage switching AC-DC-AC power converter topology is proposed. It is composed of a totem-pole type single phase rectifier

an auxiliary resonant circuit in the DC link and a single-phase full bridge inverter. The output voltage of the rectifier and the input voltage of the inverter can be changed to zero respectively via the same auxiliary circuit and the switching devices on the arm of the rectifier and inverter can achieve zero-voltage switching respectively. This paper analyzes the working process of the circuit. The experimental results on the 1.2kW prototype show that the switching devices achieved soft switching. The topological structure has reference significance for the development of energy-saving single-phase AC-DC-AC converters.
