摘要：Multi-level inverters have proved their efficiency for usage in variety of renewable energy applications. Therefore Converting DC voltage in a power bank containing multiple units using directly a multilevel inverter is a very powerful converting method. In this paper we present an analysis study of the cascaded H-bridge inverter in different conditions and different states namely 5, 9, and 17 levels. The architecture used trough the entire study is the same topology, the same command type was applied for all the models (SPWM). The study focuses on the output voltage quality and the efficiency of the power conversion. The study also discusses the influence of the unbalanced units state of charge inside the power bank on quality of the output voltage and present the most efficient level state configuration in both cases balanced and unbalanced.
