This paper describes the working principle of the Three-phase voltage PWMrectifier and the math model based on decoupling control. To improve control performance,a new type variable parameter PI controller is applied in the rectifier.MATLAB simulation is made and TMS320F2812 is used to establish a digital control platform for the PWMrectifier.Rectification and inversion can both realize a high power factor,and the variable parameter PI controller can effectively reduce the overshoot,shorten response time and improve the robustness of the system.A steady DC output voltage and quick dynamic response can be obtained.
