A novel virtual flux based direct power control space vector modulated (DPC-SVM) for 3-phase PWM rectifier with compensation of higher harmonics function is presented. The active and reactive power is used as a control variables for the PWM rectifier and active filtering operation. As a result several coordinate transformations are eliminated. Simulated and experimental steady state and dynamic performance for PWM rectifier and active filtering operation are presented. Among the main advantages of DPC-SVM are: simple algorithm, good dynamic and operation at constant switching frequency. Additionally a line voltage sensors were replaced by the virtual flux estimator which also help to achieve sinusoidal line current in case of distorted line voltage.
