Virtual flux based Direct Power Control (DPC) of three phase PWM rectifier using Model Predictive Control (MPC) and Space Vector Modulation (SVM)

A new method for control of three phase PWM rectifiers is presented in this paper. This method is classified in Direct Power Control (DPC) group among different control methods for PWM rectifiers which uses Model Predictive Control (MPC) and Space Vector Modulation (SVM). Also the method uses Virtual Flux (VF) vector of the input supply voltage that improves the performance of the rectifier under harmonic conditions of the networks. Furthermore, the method is very simple and has no complexity; There is no restriction in the method for selecting the best states of the convertor switches during each switching period. This method is tested by simulation on a typical three phase PWM rectifier under different conditions, including normal and harmonic conditions of the supply network and also in the regenerative mode.
