摘要
文章介绍了采用零电压零电流(ZVZCS)软开关方式的移相全桥PWM变换器,在分析电路工作原理的基础上进行参数设计,然后利用Simetrix仿真软件对电路进行仿真,通过仿真波形验证了参数设计的合理性以及该电路实现了降低开关损耗的作用。
This paper presents a phase-sifting full bridge PWM converter based on the zero-voltage zero-current (ZVZCS). After the principle is studied, it introduces how to choose some parameters. Then the converter is simulated by using SIMetrix, which is a powerful simulation software. The results prove that the parameters are reasonable and this converter can reduce switch loss.
