摘要

本文讨论了用移相调制控制工作在谐振频率以上的全桥LLC谐振变换器的输出电压时所观察到的功率开关的换相机理。重点是一个连续的传导模式,使从两个桥腿的所有功率器件的ZVS换相。最后给出了仿真研究的结果,验证了理论检验的正确性。

A Study of a Phase-Shifted Full-Bridge LLC Resonant Converter Operating in Continuous Conduction Mode with ZVS
This paper discusses commutation mechanisms of power switches observed when phase-shift modulation is applied to control the output voltage in a full-bridge LLC resonant converter operating above resonant frequency. The focus is on a continuous conduction mode that enables ZVS commutation for all power devices from the two bridge legs. The results of a simulation study, which confirm the theoretical examinations, are also presented.
