Abstract :
A combined system of passive and active filters for a four-wire three-phase system has been designed and simulated with Matlab/Simulink. A new control method based in the power vectorial theory and symmetrical components has been applied. The combined system mitigates the source current harmonics, compensates unbalance voltages, voltage harmonics, eliminates sags and reduces the problems of using only a shunt passive filter. The system is subjected to different voltage sources in accord to the IEC 61000. Simulation results are presented and discussed
