Abstract

An interleaved PFC rectifier reduces ripple current and a bridgeless PFC rectifier eliminates commutation loss. This study presents a dual-phase interleaved bridgeless totem-pole PFC rectifier that takes both the advantages. This rectifier operates in a variable frequency mode while achieving a zero voltage switching operation. In particular, four 650 V silicon carbide (SiC)-based transistors are applied to two boost circuits configured for a dual-phase interleaved operation. Two boost circuits operate at higher switching frequencies above 200 kHz due to the ZVS operation of the SiC-based transistors. A 500 W prototype board is implemented. The design issues of the totem-pole PFC rectifier are highlighted, and the digital control methods are applied to address them. In addition, this work investigates the conducted EMI noise of the circuit that operates with a dual-boost interleaved method at the higher switching frequencies. A single-stage input EMI filter is designed based on the analysis. Lastly, the superior switching characteristics of the SiC-based transistor are confirmed, and the overall performance of the prototype board is evaluated.
