一种基于谐振半双有源桥且具有解耦控制和固定开关频率的准单级AC-DC变换器

In this article, a resonant semi-dual-active-bridge (semi-DAB) quasi-single-stage ac–dc converter is proposed. Its multimode control strategy with smooth transition is presented. Four decoupled resonant inductor current modulation modes with fixed switching frequency control strategy are given. The resonant tank is designed in an optimized way for better performance and higher conversion efficienc...
