This paper deals with the problem of discharge balancing of batteries in case of using multilevel converters as power electronic driver for segmented permanent magnet synchronous machine. Several topologies of multilevel converters are described and analyzed. With the help of MATLAB-Simulink model two cases of battery discharge using multilevel converters are simulated. It can be concluded, that in case with multilevel inverter with independent sources when battery cell connection to H-bridge modules is binary weighted battery cells discharge faster, than in case when all batteries connected to H-bridge modules are equal.
