A new three-phase space-vector-modulated power factor corrector

A new three-phase three-wire boost-type power factor corrector (PFC) which draws sinusoidal input currents in phase with the corresponding input phase voltages is proposed and analyzed in this paper. In the proposed topology, three AC switches are placed before the bridge rectifier and across two power lines. A novel control scheme combining space-vector modulation and hysteresis current control is presented. Sinusoidal input line currents are observed in simulations.<
