A simplified approach to what you need to know.
VFDs Add Efficiency…But Create Power Quality Issues Adding a VFD to electrically control motor speed increases efficiency by limiting energy consumption and reducing equipment wear. However, VFDs inadvertently create power quality issues in the form of harmonics, which are changes or distortions in the waveforms. There are different types of harmonic distortions on the line and load side of a VFD.
