Abstract: This thesis describes the detailed study of Multi-level Inverters for 5-level and 7-level Multi-level inverters and an improvement is seen in 7-level harmonic distortion by a significant amount. Numerous industrial applications have begun to require higher power apparatus in recent years. Some medium voltage motor drives and utility applications require medium voltage and megawatt power level. For a medium voltage grid, it is troublesome to connect only one power semiconductor switch directly. As a result, a multilevel power converter structure has been introduced as an alternative in high power and medium voltage situations. The THD in 7 –level is about 28%.

Keywords: MLI, Cascaded, THD, 5-level, 7-level
