This paper introduces the operation theory of three-phase PWM voltage source rectifier（VSR）, analyses the mathematic model. Applying the voltage-oriented vector control strategy, the mathematic model and control strategy model are built based on double closed-loop control of voltage and current. Furthermore, the control strategy is simulated by Matlab/Simulink, and the results show that the control algorithm is correct and the control performance is excellent.
