| 摘要: |
| 电力电子装置产生的谐波已成为电力系统的主要谐波污染源。介绍了基于无源滤波的谐波电流注入滤波法，其基本思想是在整流电路交流侧的方波电流中叠加某次谐波电流，对方波电流进行“整形”，可减少交流侧电流的谐波含量，降低畸变率。对单相整流电路的2次谐波电流注入滤波法进行了详细分析，通过Matlab数值计算仿真，取得了良好的滤波效果。 |

| Abstract: |
| The harmonics generated by power electronic equipment become the major harmonic sources in power systems. A harmonic injection based passive power filter is introduced, in which the square wave current at AC side of rectification circuit are superposed with a hannonic current and thus shaped to reduce the harmonic components of the current at AC side and lower the distortion rate. The second-order harmonic injection in single - phase rectification circuit is analyzed in detail and simulated with Matlab. Results show its good filtering effectiveness. |
