一种用于宽范围低输入电压DC/DC电源应用、具有降低导通损耗特性的非对称半桥谐振变换器

A new asymmetric half-bridge (HB) resonant converter for dc/dc power system with a wide range of low input voltage is proposed in this paper. The proposed converter is easily derived based on the switch integration technique, merging a buck-boost, which is the same with the active-clamp forward's primary circuit, and the HB LLC resonant converter. By adopting the buck-boost circuit in front of the...
