In this paper, three phase four wire active power filter is proposed to eliminate harmonic currents both in the phases and in the neutral conductor of un unbalanced three-phase four wire electrical distribution system, feeding three single non-linear loads. A new method for identifying reference currents will be developed. It is based on pq theory using two improvements: multi-variable filter having the advantage of extracting harmonic voltages directly from the axis and the second improvement consists on the use of fuzzy logic controller to extract current harmonics components. A comparison between classical method and the new approach has been illustrated in order to find the best way to reduce network harmonic currents. The Matlab numerical code is used for all simulations in this paper.
