摘要
变频设备中的变频器产生大量6k±1次谐波,此特征谐波使电网电流波形严重畸变,THD超过国标(GB/T14549-93)限值。对此本文提出有效的谐波抑制方案,并给出了单调谐滤波器的详细设计过程,同时通过仿真分析验证了谐波抑制效果的明显性。
The inverter frequency devices generate a large number of harmonics 6k ± 1, this characteristic harmonic makes grid current waveform serious distortion, THD over the national standard （GB/T1454- 93 ） limit. This paper proposes an effective harmonic suppression program, and gives details of single - tuned filter design process, and verified by simulation of harmonic suppression effect is obvious.
