The Simulation Studies of PWM Voltage Source Rectifier under Unbalanced Grid Voltage

Abstract:

Under the balanced or unbalanced grid voltage, the PWM voltage source rectifiers should have many advantages such as sinusoidal input current, unity power factor, four-quadrant operation, the DC voltage stability, etc., so it can be employed in very broad application field. When there is only fundamental positive sequence current component in AC current, the voltage in DC side will remain constant, the rectifier will achieve efficient transformation of power quality. It is necessary to start from control strategies to eliminate harmful components such as the negative sequence current, to improve power quality in rectifier transformation. The mathematical model of PWM rectifier under unbalanced grid voltage was established in the synchronous rotating coordinate system in this paper. The simulation studies of rectifier under unbalanced grid voltage were conducted
