I used an oscilloscope to observe the sine wave of the AC current generated by these machines, and a clamp meter to check ... with a claimed THD (total harmonic distortion) of less than 3 percent ...

Not all clamp meters are the same, and this video shows just that. In a recent teardown by [Kerry Wong], the new Fnirsi DMC-100 proves that affordable doesn’t mean boring. This 10,000-count ...

Abstract: This paper proposes a modified proportional resonant (PR) based control scheme for a three-level Vienna rectifier that reduces the input current harmonic distortion [total harmonic ...

The proposed strategy can achieve minimum harmonic injection in the overmodulation region. Four-vector space vector pulse width modulation (SVPWM) renders mathematic foundations for this given method.

ABB offers harmonics surveys that help companies reduce the risk of harmonic distortion and ensure they comply with G5/4-1 recommendations. The surveys, which are carried out by ABB or a member of its ...
