A Smart Control Method based on Phasor Diagram for Voltage-Type PWM Rectifier with High Power Factor and Constant DC-link Voltage

A smart control method based on the phasor diagram for a voltage-type PWM rectifier is proposed in this paper. The proposed method uses no PI controller in order to produce the high power factor and the constant DC-link voltage. From simulation results, we can realize the constant DC-link voltage of 300 V, 600 V, 900 V or 1000 V and the high power factor over 0.98.
