摘要：

A configuration of three-phase four-wire shunt active power filter (SAPF) which included the coupled inductors and the neutral wire filter inductors was proposed in this paper to resolve the problems of increasing equipment measurement and cost due to using three uncoupled inductors in the output filter of the traditional SAPF. The positive-sequence, negative-sequence, zero-sequence equivalent models of the three-phase three-column coupled inductor which included assistant winding were deduced in detail. The decoupling equivalent circuits of the system were obtained. And the controllers of system were designed. Compared with the traditional three-phase four-wire SAPF, simulation results under mostly working conditions show not only better steady-state compensation accuracy and stronger ability of restraining switching ripple of neutral wire but also better dynamic performances for the proposed configuration. Experimental results verify the feasibility of the proposed configuration. ©, 2015, Zhejiang University. All right reserved.
