摘　　要：以单相混合型电力滤波器为对象,讨论了有源电力滤波器(APF)中谐波检测量的选取,即APF电压的不同表达式对混合电力滤波器滤波效果的影响。提出了5种APF电压表达式,这5种方式中后2种情况下都能使系统达到理想的滤波特性,一种是同时检测电网电流、负载电流和连接点处的电压;另一种是同时检测负载电流和连接点处的电压。The selection of harmonics detection components in APF（Active Power Filter） is discussed with the single-phase parallel hybrid active power filter as example,i.e, the effect of various APF voltage expressions on single-phase PHAPF（Parallel Hybrid Active Power Filter）. Five kinds of APF voltage expression are brought forward,the 4th and 5th of which can realize ideal filtering,the former is detecting source current,load current and junction voltage simultaneously,and the later is detecting load current and junction voltage simultaneously.
