Filtering is the significant criteria to keep up power quality improvement in the three stage three wire framework. Presently Active powers Filters (APF) are generally preferable for this reason. Traditional PI control techniques are disadvantageous in killing high harmonics, created by the second harmonics at the DC link of a shunt APF. This paper proposes PR control strategy which invalidates second harmonics and provides better execution exactness contrasted with the conventional positive-succession control technique and Dc link voltage control technique separately regarding quality improvement and cost adequacy. The execution of the proposed technique is shown through reproduction and test comes about.
