Abstract This paper details the energy efficiency evaluation of an Extendable-Level Inverter (ELI). ELI achieves very high voltage levels, excellent DC-link utilization, and good power quality with a minimized component count. An experimental setup three-phase is implemented to investigate losses calculate efficiency. The obtained 99.09% reduced switching conduction 0.1% 0.81% respectively. Com...

In this paper, the authors propose a new three-phase, nine-level inverter with self-balancing of capacitors voltages. The proposed is result serial connection SPUC topology and NPC converter. A single DC source used, each phase made up nine power switches three capacitors. Two control techniques are to maintain voltages at desired values, first which PWM technique ensures in open loop without u...
