摘要：
具有中线电流补偿能力的并联有源电力滤波器(APF)主电路拓扑结构主要是三桥臂电容中分和四桥臂两种。由于目前还没有对两种拓扑结构都适用的数学模型，使得缺乏对两者性能的定量比较，对于应用哪种拓扑结构更合理存在一定争议，也使得设计控制方法和进行参数优化设计时的理论还不完善。该文提出了一种三相四线并联APF主电路统一的拓扑结构，建立了它的数学模型和性能指标体系。在此基础上分析了关键参数对三相四线并联APF性能影响的规律，并对两种拓扑结构进行了定量的比较，最后通过仿真计算验证了理论推导和所得结论的正确性。该文所提出的统一数学模型为研究三相四线制并联APF提供了较好的理论基础。

Abstract:
The two wide used topologies of the main circuit of shunt active power filter(APF) which has the ability to compensate the neutral current are the three-leg split-capacitor topology and the four-leg topology. No results have been obtained for which topology is better since the existing mathematic models can't be applied to both of these two topologies. This paper propose a unified main circuit topology of three-phase four-wire shunt APF, as well as its mathematic model and performance index system. Based on the unified model, comparisons between the two topologies are achieved, and the key parameters are analyzed to show its influence on the compensation performance. Simulation results are given to show the validity of the analyses in this paper. The proposed unified mathematical model can be used as a foundation for further researches about three-phase four-wire shunt APF.
