A Novel Simulation Research on Double Closed-loop of Three-phase PWM Rectifier

Zhu Jun-jie

Abstract

The basic principle of three-phase PWM rectifier is introduced in this paper.A control strategies of decoupling of input and output current based on feedback and methods for regulation of PI is 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,and a simulation model of the PWM rectifier,which can achieve the stability of the output voltage,is established by the MATLAB R2009a.
