Comparing harmonics mitigation techniques

August 20, 2014 // By Jonas Persson, Comsys AB

The overall context is to reduce harmonic loading in a drive system.

Harmonics in power systems are predominantly caused by various semiconductor-based loads. Most common loads are drive systems (typically transistor based variable frequency drives and occasionally also line commutated DC drive systems).

The document at hand compares harmonic mitigation techniques in a range of applications and settings. Theoretical and practical comparisons are made between active and passive series and shunt filters.
