Tips: Variable frequency drive harmonic wave problems and solutionsThe devices that have switch effect in VFD main circuit will produce harmonics wave in the process of on-off circuit. The lower harmonics usually have large effect on the motor load, causing the torque ripple. And the higher harmonics increase the leakage current of the VFD output cable, causing low output. Harmonic wave interference can also lead to misoperation of the relay protection device, so that the electrical instrument measurement is not accurate, or even cannot work properly.The treatment of harmonic wave problems is to cut off the interference route transmission and suppress high harmonic wave of interference source.The methods of cutting off the interference route transmission:
The methods to suppress higher harmonic wave on the interference source:
