In this paper we propose an APF based on five-level cascaded inverter to compensate reactive power and suppresses harmonics drawn from a diode rectifier supplying RL load. The technique proposed for extraction harmonic current is balancing capacitor voltages presented a perfect compensation, a current predictive control is used for the correct operation of inverter and compensation demands. The results simulation using Matlab Simulink have demonstrated perfect performances obtained by the shunt filter active associated with cascade inverter the that the proposed shunt active power filter with predictive current controller have produced a sinusoidal supply current with low harmonic distortion and in phase with the line voltage.
