Title: Design on Anti-disturbance for Three-phase PWM Rectifier
Abstract: The basic principle of the three-phase PWM rectifier was analyzed and the model was established.With the traditional double-loop control,the load disturbance and grid voltage fluctuations have a great influence on the DC bus voltage.According to the principle of power balance for rectifier,the outer control loop which is based on feed-forward compensation(load current and power voltage) and output voltage feedback control were proposed.This method effectively improves the anti-disturbance ability of PWM rectifier.Simulation results show the effectiveness and validity of control strategies.
