A new generalized basic structure for multilevel inverter with reduced power electronic components count

This paper presents a new multilevel inverter topology which can generate all required numbers of levels at the output stage. The proposed topology is composed of six unidirectional switches, several bidirectional switches, and DC voltage sources. To add perspective, the proposed topology is compared with other topologies. The comparison shows that the proposed topology generates more voltage levels without the need for all excess number of switches and DC voltage sources. Moreover, the smaller number of switches in the current flow leads to decreased conductive loss in the proposed topology. To assure the proposed topology operates correctly, it is simulated with the aid of PSCAD/EMTDC software and the results are discussed.
