DriveTek AFE – Variable Speed Drives

Active Front End (AFE) drives use two power sections.

An active rectifier is used to minimize the amount of harmonic distortion reflected to the power grid by drawing nearly sinusoidal current from the power grid. Standard 6-pulse rectifiers used in most drives create harmonics (e.g.5th, 7th, etc.) that can generate anywhere from 30 to 100 percent current distortion. The active rectifier used in the AFE drive creates cancelling harmonics that effectively eliminate those that would be created in a standard 6-pulse drive.

An AFE drive offers several benefits over an 18-pulse harmonic reduction drive: cost, energy savings and less harmonic distortion. While the printed performance specifications may show only a slight improvement using AFE over 18-pulse, the difference can be significant in the field.
