Taking into account the increased rate of nonlinear loads in power systems, recognition and extraction of harmonics and noise seems necessary. The duty of active filter is to identify these non sinusoid currents and take action to cancel them. In this paper, adaptive method is examined and it is observed that adaptive filter might develop appropriate performance in various conditions. Specifications of adaptive filters can be changed suiting to a specific goal and such change or adaptation should be automatic and without the need for any intervention. Among such features of this filter, one might refer to its simplicity and powerful structure.
