Battery energy storages nowadays are utilized in various applications. The similarity of these applications and multilevel nature of the batteries logically encourages building of the interface converters based on a multilevel scheme. This paper is devoted to the choice of the configuration of this scheme and its operation mode. Tentative quality evaluation is made based on the root-mean declination of output voltage from its reference (THD). MATLAB-Simulink simulation is chosen as a reasonable data collection method. The results of the simulation show that a trade-off configuration may include 3-4 levels with minor inter-level pulse width modulation. In the same time further investigation must be done in order to study the influence of other technical (losses) and economical parameters.
