Abstract

This paper investigates a novel control strategy for a three-phase voltage source PWM rectifier (VSR) system with sliding mode control (SMC) and repetitive control (RP). To achieve the aim of well-controlled output DC-bus voltage, sinusoidal input currents, controlled power factor and bidirectional power flow, double closed loops control strategy are realized: i.e., outer voltage loop control with SMC and inner current loop control with the combination method of RP with PI control. The entire simulation results and experiment results are provided to demonstrate the effectiveness of the proposed control method and shows that it is in good agreement with the desired performances. In addition, the proposed method is convenient to realize and thus has a wide range of industrial applications.
