<jats:p>Active power filter (APF) is a new power electronic device used for reactive power compensation and dynamic harmonic suppression. Its performance depends on the highly precise detection of harmonic and reactive current. In view of the low pass filters defection in traditional <jats:italic>i</jats:italic><jats:sub>p</jats:sub>-<jats:italic>i</jats:italic><jats:sub>q </jats:sub>method, this paper proposes a wavelet filter based on wavelet analysis. This algorithm could attain higher detection precision with lower cost. The simulate results illustrate the efficiency and accuracy of it.</jats:p>
