A New Generalized Multilevel Inverter Topology Based on Cascaded Connection of Basic Units

As one of the key components of electrical systems, inverters have experienced great progress in the past decades, and today improving their structure and performance is a challenge for researchers. In this paper, a new multilevel converter is introduced and then, the cascaded structure is presented based on a series of introduced multilevel converter. In order to show the benefits of the proposed topology, a comprehensive comparison with the recent multilevel converters has been performed. The proposed structure requires a minimum number of power switches for the same number of levels as compared to the current structures. Also, the total blocking voltage of switches is lower than other topologies. The proposed topology can be used in medium and high voltage applications with fewer switches and less cost. In order to evaluate the performance of the proposed topology, simulation studies have been carried out through Matlab/Simulink and simulation results are presented.
