I. Introduction
Multilevel inverters (MLI) are becoming more popular in the last decade, due to their high power conversion and low harmonic content features [1]–[4]. Several MLI topologies have been recently introduced to achieve a better technology utilization and performance. The most common MLIs are the Neural point clamped (NPC), Cascaded H-Bridge (CHB) [5], [6], Flying capacitor (FC) [7], [8], and among recently introduced MLI topologies are the PUC inverter [9].
