Abstract

Abstract: Recently, Multilevel Inverters has developed as a significant substitute in the field of high and medium power industrial applications. The multilevel inverters exhibits several intrinsic advantages over traditional two level inverters such as reduced voltage stress, reduced rating of devices, and good quality of output Power. Even though Classical topologies of multilevel inverter are still utilized in most of the key areas, the cascaded multilevel inverter is considered to be the most important power converter as it is able to produce medium power output voltages with low voltage configuration of components. The cascaded multilevel inverter with reduced number of overall switch counts is an essential objective in the emerging topologies nowadays. In this paper, a comprehensive analysis of latest cascaded multilevel inverters with reduced number of switches has been reviewed and analysed. This paper will exemplify the introduction, and the qualitative parameters of these topologies. In this paper a detailed exploration of various topologies of seven level cascaded multilevel inverter based on number of switches, number of dc sources, requirement of passive components and voltage rating of power switches has been presented with which a suitable Multilevel inverter topology can be chosen for a given applications.
