摘　　要：为了使电源电流为正弦波,建立了单相有源电力滤波器的统一数学模型并分析其控制矢量图。计算等效控制量,并根据等效控制量推导对应的矢量选择规则。在Matlab/Simulink环境下对所提的控制策略进行了仿真研究,仿真结果表明所提的方法很好地抑制了谐波。This paper put forward a novel control strategy for single phase active power filter（APF） by using the sliding mode control（SMC） technology and achieved good results. For the sake of optimal control goal to enable the source being sinusoidal, the paper establishes the mathematical mode for single phase APF and analyzes its control vectors and calculates equivalent control quantity, then the SMC strategy is deduced by the equivalent control method. The simulation in MATLAB/Sinmulink was provided to verify the proposed control strategy.
