Abstract
- In this paper, we proposed a new control method for a three-phase hybrid active filter, based on a classical active filter topology connected in series with a passive filter. The non linear load is a diode rectifier feeding a (R, C) parallel load. The proposed method is based on two Self Tuning Filters placed in both feedback and feedforward loops dedicated to eliminate the 5th and 7th harmonic frequency. The feedforward loop consists in two branches, the first one to remove the 5th harmonic and the second one to remove the 7th harmonic frequency. The use of Self Tuning Filters simplifies the control scheme by reducing the number of extraction filters used in classical feedback and feedforward loops. More, in this case, no Phase Locked Loop is necessary for the feedforward loop. The effectiveness of the new proposed scheme has been verified by computer simulation and the results are compared with the classical control scheme
