Abstract: Based on the mathematic module of PWM voltage rectifier in d-q synchronization reference frame,according to the systems control goal,adopting the voltage and electic current double closed-loop control method,the PWM rectifier is obtained for  stable DC-voltage.The wave form and phase angle of input-circuit are controlled.Simulation verifies that the controlling method is rational and effective.

Key words: PWM voltage rectifier, double closed-loop, decoupling
