초록

This paper proposed a new control method for single-phase hybrid active power filter. The proposed algorithm can change single phase system into the orthogonal system which has two phases giving time-delay in regular single phase and making the imaginary second phase. It can make orthogonal system like as being used in 3Ф/2Ф transfomation with two phases. It can do complex calculation which calculates intantaneous reactive power. Istead of existing method applying to intantaneous reactive power theory in fixed reference frame, this paper proposed the algorithm which has advantage over reducing harmonics using rotating reference frame. It verified the effectiveness the proposed method through simulation and experiment.
