To suppress various types of harmonics, a design scheme for a new series hybrid active power filter, which is composed of series active power filter based on fundamental magnetic flux compensation and parallel resonance passive filter, is proposed, and the structure and principle of the new series hybrid active power filter are analyzed. In the proposed structure the problem that the over-current is easy to occur in the passive part of traditional series hybrid active power filter is solved. The system parameters of the new series hybrid active power filter are designed, and a floating control strategy for improved proportion integration (PI) controller is put forward. The effectiveness of the proposed structure and control strategy is verified by simulation results.
