Abstract

This paper presents a improved predictive current control of three-phase AC-DC PWM converter, which achieves unity power factor, harmonics elimination and DC-bus-voltage constant. This paper focuses on predictive current control strategy of which the control principle and the reason of static phase error existing in the AC side current are studied. And the paper presents improved predictive current control strategy, which solves the problem of static phase error existing in the AC side current in traditional predictive current control strategy using periodic phase information of voltage. The proposed three-phase AC-DC PWM converter was tested both in simulations and experiments. Results have proved excellent performance and verify the validity of the control system.
