摘要
Abstract
This paper sets up The mathematical model in dq axis of three-phase PWM rectifier's main circuit. Because the mathematical model of traditional three-phases PWM rectifier which is set up by switching function is a non-linear model, it's relatively difficult to design the controller. In the way of the average switching period, three-phase PWM rectifier is set up, after which the steady-state model and small-signal model are obtained respectively by separating the disturbance. Therefore, the PI controller of the voltage outer loop and the current inner loop is designed in small-signal model. Lastly, the the validity of small-signal model and the controller is verified throng the PSCAD simulation.关键词
