This paper proposes a balancing of sub module capacitor voltage in modular multilevel dc (MMDC) converter. Generally used MMC balancing procedure cannot be used, since arm currents of MMDC changes its direction within each switching cycle. Here the average capacitor voltage of each arm is self balanced within an arm by assigning the gate signals. This 5 level DC-AC-DC converter drives DC system. In regenerative mode of DC motor the energy in the motor winding is released and charges the battery. Battery associated with bi-directional dc/dc converters operate in buck mode while it is charging and in boost mode when discharging. Simulation work for proposed topology is carried in MATLAB/Simulink.
