摘要
This paper reviewed the topologies and soft-switching (also called Zero Voltage Switching, ZVS) for the high-frequency GaN-based single-phase Bridgeless PFC. First, a brief introduction of single-phase bridgeless PFC has been presented. Then a review of the bridgeless PFC topologies has been given. Next, the theoretical analysis of the ZVS and the state plane trajectory is introduced and the case study for the two-phase Totem-Pole PFC and Dual-SEPIC PFC is presented. Finally, the prototype for Totem-Pole PFC and Dual-SEPIC PFC are built, and the soft-switching has been achieved with high efficiency based on the ZVS extension strategy.
