摘要

为改善单相全桥逆变器的效率，提出了一种高效率单相全桥谐振极软开关逆变器拓扑结构，其辅助电路与逆变器桥臂相连，且只含有1个辅助开关和少量无源器件.在逆变器工作过程中，主开关和辅助开关都能实现软切换，通过降低开关损耗来实现逆变器高效率运行.文中分析了电路工作过程，实验结果表明开关器件实现了软开关，这为进一步研发高性能的实用新型单相全桥软开关逆变器奠定了技术基础.

Abstract

A topology of high-efficiency single-phase full bridge resonant soft-switching inverter is proposed to improve efficiency of single-phase full bridge inverter. The auxiliary circuit is connected with the bridge arm of the inverter and contains only one auxiliary switch and a small number of passive devices. The main switches and auxiliary switch can achieve soft- switching in the working process of the inverter. High-efficiency operation of the inverter can also be achieved by reducing switching loss. In this paper

the working process of the circuit is analyzed. The experimental results indicate that the switching devices can achieve soft-switching

which lays a technical foundation for further research and development of a new practical single-phase full bridge soft-switching inverter with high performance.
