Abstract :
A new control algorithm for a hybrid filter formed by a series active filter and a passive filter connected in parallel with the load is proposed. The new control strategy is based on the dual formulation of the vectorial theory of electric power, so that the signal injected by the active filter is able to compensate the reactive power and the harmonics of the load current. To verify the developed theoretical analysis, the proposed control scheme has been simulated in the platform MATLAB-Simulink and applied to a three-phase three-wire system. The simulation results to verify the effectiveness of the proposed control algorithm are presented.
