具有平衡电容电压的高变比双向谐振变换器中瞬时无功功率的消除

This article presents bidirectional operation of a resonant converter that features high step-up/down capability, high efficiency, and balanced capacitor voltage. When transferring power in the backward direction, the original converter may suffer from significant reverse current due to large fluctuation of the resonant capacitor voltage. By applying the right amount of phase in the pulsewidth-mod...
