This paper presents a new control scheme using Self Tuning Filter placed in both feedback and feedforward control of a parallel hybrid active filter. This hybrid active filter is intended for harmonic compensation of a diode rectifier. The use of self tuning filters simplifies the control scheme by reducing the number of extraction filters, used in classical feedback and feedforward loop. More, in this case, no Phase Locked Loop is necessary for the feedforward loop. The studied hybrid active filter consists of an active filter and three phase tuned LC filters for 7th harmonic frequency. The non linear load is a diode rectifier feeding a (R, C) parallel load. The effectiveness of the new proposed scheme has been verified by computer simulation and the results are compared with the classical control scheme.
