A Cascaded Modular Multilevel Inverter Topology Using Novel Series Basic Units with a Reduced Number of Power Electronic Elements

Abstract

In this investigation, another sort of cascaded modular multilevel inverters (CMMLIs) is exhibited which can create a significant number of output voltage levels with a sensible number of segments. In like manner, every arrangement phase of the proposed CMMLI is contained two same fundamental units that are associated with each other through two unidirectional power switches without pointing any of the full H-bridge cells. Also, since the probability for producing a higher number of output voltage levels in CMMLIs depends on the greatness of the dc voltage sources utilized as a part of every arrangement unit, in whatever is left of this paper, four unique calculations for deciding a fitting an incentive for the dc sources' size are additionally introduced. In the accompanying, a far reaching topological investigation between some CMMLI structures revealed in the writing and proposed structure along with a few reproduction and trial results will be likewise given to approve the lucrative advantages and practicality of the proposed topology.
