A New Structure with New Algorithms for Cascaded Multilevel Inverters by Reducing Number of IGBTs

Cascaded multilevel inverters are usually used in a medium-voltage output. Hence, this converter has been declared as a vital substitute in the average-voltage inverter. In this article a novel structure for cascaded multilevel inverters have been proposed. Also, five algorithms are suggested to determine the amount of resources which are used in the new structure. The suggested topology has a number of benefits, including reducing the quantity of IGBTs and switches and required fee and installation area. Another benefit of the suggested structure is lower variety of the values of dc voltage sources in comparison with conventional structures. In this paper, the ability of proposed topology to produce all voltage levels with the result of the simulation is given to a17-level inverter.
