Title: Research on design method of control system for three-phase voltage source PWM rectifier
Abstract: The mathematical model in dq axis of three-phase PWM rectifier’s main circuit is set up in this paper.Current control with feed-forward and decoupling strategy is selected.The double loop control system is designed and the stable DC voltage and the high power factor of the PWM rectifier are regulated by three PI controllers.By building the small signal model of transfer function from the voltage loop’s output to the DC bus voltage,the control block diagrams of the voltage loop and the current loops are set up,then their PI controllers are designed.At the end of the paper,simulation and experimental results are given to verify the proposed analysis and design.
