Redundant and backup energy source is crucial in both household and industry. Energy storage systems are already used extensively to provide solutions to various issues such as grid frequency stabilization and electrification of remote areas. In addition to that, they can cover potential excessive energy demand when required. One of the most important parts of battery energy storage systems is power electronic converter that is used for the power transmission from the batteries to the grid and vice-versa. A typical power electronic converter topology is the multilevel converter with independent sources. This topology has several advantages compared to other topologies utilized in battery energy storage systems, such as, lower harmonic distortion of the output waveforms and battery balancing which can be obtained in natural way. This paper investigated and presents a modified multilevel converter with independent sources - multilevel converter with unfolding stage and voltage regulators.
