摘　　要：为有效治理不同类型的谐波,提出了新型的串联混合型有源滤波器设计方案。该系统由基于基波磁通补偿的串联型有源滤波器和并联谐振型无源滤波器组成。分析了系统的结构和原理,该结构克服了传统串联混合型有源滤波器中无源部分容易过流的问题。设计了系统参数,提出了改进的比例积分(proportion integration,PI)无静差控制方法。仿真算例验证了所提结构及控制策略的有效性。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.
