Current-THD minimization in multilevel inverters with variable DC ratios utilizing a generic closed-form analytic formulation of line-voltage WTHD

This article presents a generic approach to load-current THD minimization in hard-switched Staircase Modulation (SCM) based three-phase (3ɸ) Multilevel Inverters (MLI) with either fixed or variable DC source Ratios (DCR). First, a computer-aided closed-form analytical formulation of Weighted THD (WT...
