为了提高并联型有源电力滤波器(Shunt Active Power Filter, SAPF)的电流跟踪性能，提出一种基于SVPWM的并联型有源电力滤波器的电流跟踪控制算法。由于SAPF参考指令是电流值，而SVPWM参考指令是电压值，因此根据电流电压内在关系将SVPWM控制算法与SAPF的参考指令电流相结合，通过改变SVPWM调制方式减少功率器件的开关次数，从而降低功率器件的开关损耗，提高控制性能。并且通过构造Lyapunov函数，对SVPWM控制的SAPF的稳定性进行了分析。仿真和实验结果证明该算法简单，可以很好地跟踪指令电流，能实现对SAPF的实时控制,并且具有非常好的谐波补偿效果。SAPF在负载扰动下的补偿效果证明了关于SVPWM控制的SAPF的稳定性分析的正确性。

To improve the current tracking ability of parallel Shunt Active Power Filter (SAPF), a current tracking control algorithm based on Space Vector Pulse-Width Modulation (SVPWM) is proposed. The reference instruction of SAPF is the current value, but the reference instruction of SVPWM is the voltage value, so based on the internal relationship between the current and voltage, the control algorithm of SVPWM is combined with the reference current of SAPF, and by changing the modulation way of the SVPWM, the switching frequency of power device is decreased, which can reduce the switching loss and improve the control performance. By constructing the Lyapunov function, the stability of SAPF controlled by the SVPWM is analyzed. Simulation and tests show that the algorithm is simple, it can track the instruction current well, the real-time control of SAPF can be realized, and it has good harmonic comparison results. The compensation results of SAPF under the load disturbance prove the correctness of the analysis of this paper on the stability of SAPF controlled by the SVPWM.
