3-Channel Interleaved CCM PFC Using the FAN9673 180 to 264 VAC Input, 5kW CCM PFC Controller

AN4165/D, Typical application circuit presents practical design considerations for a 3-channel interleaved CCM boost PFC employing the FAN9673. It includes the procedure for designing the boost inductor and output filter, selecting components, and implementing average current mode control. The design procedure is then verified through an experimental 5 kW prototype converter
