350-W, Two-Phase Interleaved PFC Pre-Regulator Design Review

In these high power applications interleaving PFC stages can reduce inductor area and reduce output capacitor ripple current. This is made possible through the inductor ripple current cancellation that occurs with interleaving. This application note reviews the design of a 350-W two phase interleaved power factor corrected (PFC) pre-regulator.
