Therefore, the use of this topology in the most diverse application areas has been studied, especially in high voltage direct current transmission systems.

The algorithm used to implement the balancing of submodules’ capacitor voltages was developed based on sorting methods, but also considering the cost function idea. In order to verify the performance of the adopted strategy, qualitative analyses were made based on simulation results conducted in the environment of circuit simulation PSIM, in which the logic of the control system was programmed in C language.
