Abstract: In order to solve the pain points of high temperature rising of IGBT and bridge rectifier, and large size of heatsink in 3 HP RAC, this paper proposed totem pole PFC with hybrid IGBT IKZA50N65RH5 as switch for high frequency leg, and built its CCM mode simulation model with average current control algorithm by PLECS, then got the highest efficiency 97.924% on 3.3 kW totem pole PFC evaluation board, and the switching frequency of IGBT was 65 kHz. It is helpful to decrease temperature rising of IGBT, improve system reliability.

Key words: 3 HP RAC, totem pole bridgeless PFC, hybrid IGBT
