Abstract: Predictive direct power control (P-DPC) has been suggested as an effective alternative to the conventional direct power control (DPC) applied to PWM converter such as active power filter (APF) and PWM rectifier. It is characterized by a high transient dynamic, which makes it an interesting alternative for conventional direct power control (DPC). Furthermore, in the existence of a non-linear load, the source currents would become highly distorted under perturbed and unbalanced voltage grid conditions. In order to resolve the problems mentioned above, the present paper proposes an improved P-DPC control for APF based on disturbance rejection principle, which is able to operate under balanced, unbalanced and distorted grid voltages conditions and can attain sinusoidal source currents with a respectable total harmonic distortion (THD) meets with IEEE-519 standard. Simulation results and comparative study are presented to confirm the efficiency of the proposed approaches.
