一种基于电压倍增整流器的超宽范围脉宽调制LLC变换器

This article presents a voltage multiplier rectifier-based LLC resonant converter that achieves an ultrawide range of the output voltage with pulse width modulation (PWM) of the auxiliary switches on the secondary side. Compared with the pulse frequency modulated LLC topologies, the proposed topology operates at a fixed frequency and features a bounded voltage gain range. Thus, the resonant tank d...
