Abstract
The authors address the problem of optimal current quality for a single-phase
multilevel inverter with a staircase modulation (Fig.1). The current quality is characterized by current
ripple Normalized Mean Square (NMSc). The goal is to find theoretically optimal switching angles and
respective minimal NMSc values. The previous research didn't provide comprehensive solutions for
arbitrary modulation indices and level counts.
