Abstract

A three-phase PWM AC-DC converter with high power factor (PF) using hybrid-clamped five-level topology is researched in this paper. The mathematical model and control strategy are analyzed. In addition, a novel method to determine ac-side inductance according to required current ripple is proposed. Simulation and experimental results show the dc-link capacitor voltages imbalance extensively existing in multilevel converters can be solved, and the power factor correction is realized on the grid side.
