Abstract
This paper proposes a novel and simple direct power control scheme for three-phase PWM rectifiers operated at constant switching frequency using space vector modulation (DPC-SVM). The active and reactive power is used as the pulse width modulated (PWM) control variables instead of the three-phase line currents usually used. Moreover, a line voltage sensors are replaced by virtual flux (VF) estimator. Theoretical principle of this method is discussed. The steady state and dynamic results of DPC-SVM scheme that illustrates the operation and performance of the proposed system are presented. It is shown that DPC-SVM exhibits several features as: simple algorithm, good dynamic response, constant switching frequency and particularly provide low THD sinusoidal line current when supply voltage is no ideal. Simulated and experimental results have proven excellent performances and verify the validity of the proposed system.
