摘要

提出一种新颖的两相交错并联软开关双向DC-DC变换器,该变换器的软开关辅助电路由一个电感和一个电容串联组成。该辅助电路不仅能实现两相间共享,且在一个周期内只工作一次。介绍该变换器的拓扑结构及软开关工作原理,分析不同占空比下的关键波形与软开关实现条件,提出一种基于峰谷值检测的全范围软开关调制方法,并进行拓扑推演。搭建一台250 W的样机验证,实验结果显示,该变换器的所有开关管均能实现零电压开关,其峰值效率可达99.38%。

Abstract

A novel two-phase interleaved soft-switching bidirectional DC-DC converter is proposed. The soft-switching auxiliary circuit of the converter is composed of an inductor and a capacitor in series. The auxiliary circuit can not only realize the sharing between two phases, but also work only once in a cycle. This paper presents the topological structure and soft-switching operating principles of the converter; analyzes the key waveforms under different duty cycles and the conditions for achieving soft-switching; proposes a full range soft-switching modulation method based on peak-valley value detection; and performs topology deduction. Finally, a 250 W experimental prototype is built for verification. The experimental results show that all the switches of the converter can achieve zero-voltage switching, and the peak efficiency can reach 99.38%.
