Abstract :
PWM rectifier is called green energy conversion device, it can be widely used in motor control field for the steady DC bus voltage and unit power factor. The waveforms of DC bus voltage and input current are simulated and analyzed for different load and power network of different parameter. The control strategy is provided based on MFAC, and the PWM rectifier system of voltage-source current-control is designed. The results of simulation show that this control strategy can decrease the DC bus voltage ripple introduced by negative sequence voltage.
