Abstract. The mathematic model of three-phase voltage-source PWM rectifier was given in three-phase sta-tionary coordinate system and two phase synchronization coordinate system. The direct current controlstrategy and the control structure of voltage outer loop and current inner loop were chosen. The designmethod of voltage and current loop PI controller were given, and the calculation of AC inductor and DC ca-pacitor were also presented. Simulation model was established in MATLAB/SIMULINK environment andsimulation results verify the correctness of the main circuit parameters.
