active harmonic mitigation - what the manufacturers do not tell you

Any drawbacks of Active harmonic mitigation?

Active harmonic mitigation with AFE drives In this article we will once again touch the topic of grid side harmonics, particularly focusing on active harmonic mitigation with AFE drives. Abbreviations used: AFE = Active Front End APF = Active Power Filter ASD = Adjustable Speed Drive (synonym to VFD) DFE Read more…

Network harmonics: VFD harmonic spectrum

VFD harmonic spectrum Introduction After the theoretical introduction [1] we jump to variable frequency drives as sources of harmonics. This post is about VFD harmonic spectrum. As already mentioned, VFDs belong to non-linear devices with non-sinusoidal currents and/or voltages that they draw from the grid or inject into the grid. Read more…
