Where Do VFD Harmonics Come From and How to Mitigate Them?

In modern industrial automation, Variable Frequency Drives (VFDs) have become essential for achieving energy savings and precise motor control across countless applications. From conveyors and pumps to fans and compressors, VFDs regulate motor speed by varying the frequency and voltage of input power. However, despite their operational benefits, VFDs introduce an inherent electrical challenge: harmonic distortion
