用于通用电动汽车充电器的PWM控制串联谐振变换器

This article presents a pulsewidth modulation (PWM) controlled series resonant converter (SRC) for a universal EV charger. This article focuses on the boost mode of a SRC. By adapting two PWM boost switches with a full bridge rectifier, it is possible for a SRC to cover a very wide range of gain with a high and flat efficiency curve. As the output voltage increases, the secondary side rectifier of...
