چکیده :

Inverters as one of the most important elements of power systems have been profoundly developed in recent decades and their performance has attracted researches in control and structure point of view. In this paper, a novel structure based on low power switch count is proposed for multilevel converter is feeding. The proposed structure is presented for symmetrical/asymmetrical mode and the number of power electronic devices is decreased in comparison with similar works. Considering recent proposed structures, the proposed structure has superior condition in terms of semiconductor switches and drivers count as well as Total Blocked Voltage (TBV). The performance of the proposed symmetrical 29-level converter is analyzed and simulated in MATLAB/Simulink.
