Design of 31-level Asymmetric Inverter with Optimal Number of Switches

In this paper, 31-level asymmetric inverter is designed using optimal number of switches which produces higher output voltage levels with low harmonic distortion. The voltage sources used in this multilevel inverter is asymmetric in nature to generate output voltage with reduced distortion. By using six asymmetric voltage sources and 10 switches, 31-level inverter is simulated and the results of the inverter topology are studied in view of reduced harmonic components.
