Totem-pole bridgeless PFC is a very promising topology for GaN devices because of very low reverse recovery. However, inherent challenges exist for this topology at zerocrossing point of AC voltage ...

This paper presents a detailed analysis of a single-phase GaN-based power factor correction (PFC) critical-conduction-mode (CRM) totem-pole rectifier with zero-voltage-switching (ZVS) control. The ...
