Partial Power Processing Based Two-Stage Half-Bridge Resonant Converter With Reduced Component Count

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 regulator, it results in a relatively high partial power processing ratio or a large number of circ
