摘　　要： 提出一种基于瞬时无功功率理论的谐波电流检测方法,并将其应用于单相有源电力滤波器(APF)中从而获得指令电流,同时还介绍SVPWM(空间矢量脉宽调制)应用于谐波电流控制技术,通过Matlab仿真表明两种算法均结构简单,计算量小,实时性好,对补偿电流的指令可快速的跟踪,数字化程度高。 This paper proposes a harmonic current detection method based on instantaneous reactive power theory and applied to single-phase active power filter（APF）in order to obtain the current instruction.It also introduced SVPWM（space vector pulse width modulation）is applied to the harmonic current control.Matlab simulation results of two algorithms show that both the algorithm structure is simple,small amount of calculation,real time,high degree of digitization,and it can also quickly track on the compensation current command.
