3 Introduction to the Low Harmonic Drive

3.1.1 Working Principle

The VLT Low Harmonic Drive is a VLT High Power adjustable frequency drive with an integrated active filter. An active filter is a device that actively
monitors harmonic distortion levels and injects compensative harmonic current onto the line to cancel out the harmonics.
