The Role Of Harmonic Filters In Suppressing Current Fluctuations

low harmonic vfd Reduces current waveform distortion by identifying and filtering high-order harmonic components in the output current of the power grid or equipment. Specifically, in AC power supply systems, nonlinear loads can cause current distortion including 5th, 7th, and higher harmonics, leading to current fluctuations. power harmonic filter Directs these harmonic components to their filtering circuits, using resonant or reverse-injected compensating current in filtering elements (such as inductors, capacitors, or inverter control paths) to weaken these abnormal frequencies and restore the stability of the dominant frequency components.
