In this paper, how the switching cost and total harmonic distortion can be reduced by using new topology of multilevel inverter. These topology can be extended for any level of multilevel inverter. In this paper, the mode of operation for 5-level inverter can be discussed, similarly modes of operation for higher level can be analyzed. This paper also demonstrate the simulations of seven level 3-φ multilevel inverter. This new topology shows that the three single phase multilevel inverter build

... three phase seven level multilevel inverter, It also presents the seven inverter along with harmonic reduction and less number of switching components. The harmonic reduction can be achieved by selecting appropriate switching angle. This proposed technology contains advantage to it's less number of components in comparison with cascade H-bridge multilevel inverter. Basically in this inverter, reducing THD and number of switches so that we may get optimum power flow and smooth shine wave shape, thus it is very appropriate to connect with grid.
