Based on feed-forward decoupling control strategy, the model and controller of three-phase voltage source PWM rectifier are presented. First of all, a mathematical model of three-phase voltage source PWM rectifier is established in the d-q rotation frames. The double loop system is designed based on feed-forward decoupling strategy, and three PI controllers are designed. The simulation results show that this method can make PWM rectifier run with unit power factor, the output DC voltage stabilize on the desired value with the fast dynamic response. The characteristics meet the design demands.
