1.5kW Digital Totem Pole PFC Design for Air-Conditioner Using iMOTION Digital Controller

Figure 1: Simplified hardware diagram

A lot of research focuses on bridgeless PFC in order to achieve higher system efficiency compared to traditional boost PFC. Most of the bridgeless PFC solutions suffer from EMI issues, which cause problems in applications where an  inverter stage shares the same ground. In this case, the PFC
