The configuration and the working principle of a novel series - parallel hybrid active power filter based on iundamental magnetic potential self - balance are analyzed. A novel design method of the passive filter is given. In this design method, all design demands and constraints of passive filter branches are comprehensively considered and the known design experiences are also applied. The validity of the theory and the excellent compensation characteristics are verified by an experimental prototype with two kinds of typical harmonic - producing loads.
