摘要

本文提出了一种基于三态换向单元的高电压增益单级DC-DC变换器。所提出的变换器工作在软开关ZVS模式的所有开关。为了验证所提出的结构，给出了工作原理、项目规格和500W样机的实验结果。结果表明，软开关换相性能好，应力减小，效率高(94%以上)。

High voltage gain single stage DC-DC converter based on three-state commutation cell

This paper presents a high voltage gain single stage DC-DC converter based on the three-state commutation cell. The presented converter operates with soft-switching ZVS mode for all switches. The operation principle, project specifications, and experimental results from a 500W prototype are presented in order to validate the proposed structure. The results show de soft switch commutation, reduced stress and high efficiency (over 94%).
