基于部分功率处理的两级半桥谐振变换器及其元件数量优化

Partial power processing is an attractive solution that processes only a portion of the total power, which has the advantage of increasing efficiency. It can maintain high efficiency over a wide input range when combined with two stages. Since the conventional two-stage partial power processing structure adopts a full-bridge topology or multiple transformers to achieve smooth integration with a dc...
