Abstract: The basic principle of three-phase PWM rectifier is introduced.The control strategies of decoupling of input and output current based on feedback and the methods of PI regulation are used,and the simplified mathematical model of the PWM rectifier of the current inner loop and outer voltage is established,which is based on the model of the d-q synchronous rotating coordinate system in three-phase rectifier.A simulation model of the PWM rectifier,which can achieve the stability of the output voltage,is established by the MATLAB R2009a.The simulation results verify that the proposed method is effective and practical.

Key words: PWM rectifier, PI regulator, current decoupling, MATLAB
