A Simplified Topology for Seven Level Modified Multilevel Inverter with Reduced Switch Count Technique

In this paper, a seven level modified cascaded multilevel inverter is proposed for industrial drive applications. Apart from selecting the conventional level inverters, Multi level inverters has been chosen for the industrial drive applications as it reduces the total harmonic distortion. The involvement of higher number of switches increases the complexity of the system, which leads to losses in switching, producing huge harmonics and in the end, it entirely reduces the efficiency of the system. The cascaded multilevel inverter involves only fewer switches, where it reduces the complexity of the system which in turn reduces the harmonics and reduces the complexity of the system and in total it reduces the total harmonics distortion.
