Abstract

A PFC circuit for applications higher than 2 kW is generally configured by an interleaved structure, which reduces component stress and the ripple of inductor currents and output voltage. However, when implemented with GaN HEMT and controlled by a double sliding mode, a high-power totem pole PFC could achieve better performance without an interleaved structure.
