| 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。 |

| Abstract: |
| 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 4 th and 5 th 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. |
| Key words: parallel hybrid active power filter,passive power filter,harmonics detection component |
