Abstract: The present invention relates to a method for SOC balance control of a battery charging and discharging system having a cascade H-bridge multi-level structure, which comprises the steps of: (a) controlling a DC link voltage ratio of each module at a ratio of 1:2:3:4 by operating a 2-quadrant interleaving 21-level converter; (b) outputting a reference value of a voltage level to be output at every control cycle by receiving an output voltage reference value generated by a current controller as a round () function, by the 21-level converter; (c) selecting a gate pattern for forming the reference value voltage level of the 21-level converter, by a look-up table of the gate pattern; and (d) forming an output voltage by operating each module using the gate pattern for maintaining a current conduction time of the module associated with a battery having a highest SOC for a predetermined time by periodically measuring the SOC of the battery associated with each module, by a controller. The method of the present invention as above can form an output voltage close to sine using a small number of H-bridge modules, reduce harmonics of the output voltage and current through a harmonic reduction algorithm, and actively suppresses the SOC unbalance of the battery associated with each module by connecting the four H-bridge modules having a voltage ratio of 1:2:3:4 in series to form the 21-level output voltage and suppressing the SOC unbalance of the battery associated with each module according to the proper selection of the gate pattern, thereby improving the utilization of the battery.
