By applying orthogonal linearity of wavelet transformation, a self adapting filter is designed on the basis of wavelet algorithm and is effectively applied to power active filter. As indicated by results of Matlab simulation, this power active filter based on self-adapting wavelet algorithm is fairly good in elimination high-order harmonic wave and noise and in compensating reactive current of power frequency, and it is fairly fast in convergence
