Techniques like selective harmonic reduction are proposed in this project's proposal. The harmonic content of a single phase cascaded multilevel inverter was reduced using SHE. For inverters with five to eleven levels of levels, the firing instants for the electronic switches are computed off-line. Four independent voltage sources with voltage output levels in a certain ratio make up the novel module structure proposed in this concept. In recent years, multilevel inverters have been a hot topic because of their ability to handle high-power applications. This paper suggests. To minimise harmonic content in a single-phase cascaded multilevel inverter, this study uses the selective harmonic elimination approach . As output levels grow, so does the number of switching components required to perform the switch. There is a risk of power loss and a decrease in overall system efficiency due to the increased number of switches. Most notable is that the module may be utilised as a submultiple level structure and expanded for any number of levels with minimum increase in switching components (pho). MLI's superior power quality, decreased total harmonic distortion (THD), lower voltage stress across the switches, improved electromagnetic compatibility, and fewer switching losses are attracting a lot of attention.
