Research on Current Control Strategy of Three-Phase Three-Line Active Power Filter

The paper is talked about a current control strategy of three-phase three--line active power filter（APF）. The main circuit topology adopts a voltage source converter, which is constituted by three H--bridges of delta--connection H--bridge topology. The control system carries out independently three single--phase converter . This paper presents a compound control methods, which can achieve the ideal control effect of the harmonic current, reactive current. On the basis of theoretical analysis and simulation, experiments verify the effectiveness of the proposed method on a high power active power filter.
