In this paper, a new three-phase power-factor correction (PFC) scheme is proposed using two single-phase PFC, modules. In this approach, the three phase input is first transformed to two phase by means of a 0.14-pu-rated autotransformer. Two standard single-phase PFC modules are then employed to process the two phase power to dc output. Split inductors and diodes are employed to limit interaction between the two PFC stages. Due to cascade operation of two PFC stages, low-frequency (120 Hz) ripple in the dc-link capacitor is cancelled. Detailed analysis and simulation results are presented. A 220-V 1.5-kVA design example along with experimental results is shown.
