摘　　要：三相四线制有源电力滤波器能够很好地提高滤波器的滤波性能,实现在大功率场合下的谐波抑制和无功补偿。通过研究主电路拓扑结构,给出了主电路设计方法,包括触发电路的设计,IPM驱动电路的设计和同步信号电路的设计。综合运用瞬时无功理论中的p-q法和ip-iq法,提出了一种新的基于瞬时无功理论的有效的三相四线制谐波检测新方法,此方法能将三相电流中的零序电流剔除。最后文章利用M atlab/S imu link构建了仿真模型,设定了仿真模型中各部分的参数,仿真结果验证了该方法的准确性和有效性。Active power filter in three- phase four- wire system can effectvely improve the filter performance and realize harmonics restraint and reactive power compensation in large power situation. A design method of main circuit is presented by studying the scheme of main circuit. It includes design of trigger circuit, IPM driving circuit and locking signal circuit. A new method of three-phase four-wire harmonics detection is given, based on p-q method and ip-iq method of the instantaneous reactive power theory. This method can remove the zero sequence current. Finally, based on Matlab/Simulink simulation model is established, and its parameters are set. The result of the simulation shows that the method is correct and effective.
