Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The paper suggests Selective Harmonic Mitigation problem formulation as a time domain constrained optimization Total Harmonic Distortion minimization with selected mitigated harmonic magnitude inequality constraints. The results of optimization are presented in the form of dimensionless criterion that allows to trade-off more grid current for less coupling inductance (or vice versa). Though an elementary two-level three-phase inverter is considered, the general approach is applicable to different multilevel inverters and modulation strategies.
