次级侧带陷波滤波器的多元件谐振变换器

This letter proposes novel multielement resonant converters, which are improved topologies of the conventional LLC resonant converter, for voltage step-up applications. A notch filter is introduced into the secondary side of the LLC resonant converter. The voltage gain of the proposed resonant converters can be as low as zero with limited switching frequency range. Therefore, the start-up and shor...
