中文说明：用于缓解谐波和无功功率补偿的并联有源滤波器的 Matlab 仿真模型。直流侧电容电压调节采用 pi 控制器和 vsi 逆变器的开关信号产生的滞环电流控制器。结果表明，源电流使用有源电力滤波器后, 成为自由的谐波，总谐波失真已下降
English Description：
Matlab simulink model for shunt active filter used for harmonics mitigation and reactive power compensation. The dc link capacitor voltage is regulated by using pi controller, and the gating signals for the vsi inverter is generated by hysteresis current controller.Results show that source current became free of harmonics after using the active power filter, and the total harmonic distortion has decreased
