Phase Converters, VFDs and Low Harmonics. Why Should I Care?

Phase Converters, Variable Frequency Drives (VFDs) & Low Harmonic Requirements. What Do They Have In Common, and Why Should I Care?

Variable Frequency Drives (VFDs) and phase converters are commonly used in a variety of industrial and residential applications. Most VFDs produce significant levels of harmonic distortion that negatively affect power quality and can degrade transmission and distribution equipment. Standard three-phase VFDs are frequently used as phase converters.

When used in this mode they create a unique harmonic profile that is resistant to most available harmonic mitigation solutions. Today’s presentation will review VFD and phase converter harmonics, their impact, and harmonic mitigation technologies.
