Abstract :
Dynamic response of DC bus voltage for PWM rectifier is very important, because higher response means little DC bus capacitor. A fuzzy logic controller for the DC bus voltage was designed in this paper in order to improve the dynamic response.. The overshoot and the start-up time of the DC bus voltage response for the traditional PI controller and fuzzy logic controller were compared respectively. Simulation results show that with the presented fuzzy logic controller, the system exhibits better dynamic performance than that of traditional PI controller.
