摘要

本文提出了一种采用再生缓冲器的改进ZVT DC-DC升压功率变换器。所提出的缓冲器采用磁耦合单元来降低辅助开关的关断开关损耗。该方法已被用于建立一个500w / 100khz的原型。实验结果显示了带和不带再生缓冲器的ZVT DC-DC升压变换器波形。采用所提出的改进方法，实现了较高的效率。

Improving the operation of ZVT DC-DC converters

This paper presents an improved ZVT DC-DC boost power converter using a regenerative snubber. The proposed snubber uses a magnetically coupled cell to reduce the turn-off switching loss of the auxiliary switch. The method has been employed to build a 500 W/100 kHz prototype. The experimental results show the ZVT DC-DC boost converter waveforms with and without the regenerative snubber. A high efficiency is achieved using the proposed improvement.
