| Abstract: | This paper introduces the working principle of the three-phase PWM rectifier.A direct power control strategy with constant switching frequency is proposed,and Space Vector Modulation(SVM) is applied to the scheme.Then the simulation model is established for analysis by Matlab/Simulink.The results show that input sin current and unity power factor are achieved and the proposed method has excellent dynamic and steady state performance |
