摘　　要：基于三电平有源电力滤波器(APF)数学模型,针对传统PI双闭环控制性能的不足,提出一种将内模解耦控制与三电平电压空间矢量脉宽调制(SVPWM)控制相结合的控制方案。根据内模控制原理,详细设计了APF双闭环内模控制器,优化了APF整体性能。仿真与实验结果表明该方案取得了良好的补偿效果。Based on the three-level active power filter（APF） mathematical model and the deficiency of the traditional double-loop control performance of PI, an improved method by combining internal model decoupling control and threelevel voltage space vector modulation（SVPWM） is provided.According to internal model control principle,the APF double loop internal model controller is designed, the overall performance of APF is optimized.The simulation and experimental results show that the program has good compensation effect.
