A modular multilevel converter system. The system includes a plurality of series connected two-terminal M2LC subsystems and a control system module. The two-terminal M2LC subsystems are arranged into at least two output phase modules. A first one of the output phase modules defines a total value of inductance and includes a positive arm and a negative arm. The control system module is communicably connected to the two-terminal M2LC subsystems of the first one of the output phase modules. The control system module is configured to apply selectively reassigned modulated switch functions to only one of the following at a given instance of time: the two-terminal M2LC subsystems of the positive arm of the first one of the output phase modules or the two-terminal M2LC subsystems of the negative arm of the first one of the output phase modules. The selective reassigning of the modulated switch functions forces charge balance of the individual capacitors of the series connected two-terminal M2LC subsystems at a predetermined rate.
