Zusammenfassung:Multilevel inverter has been identified as an attractive topology for high power applications. The main objective of this paper is to compare a cascaded 7-level inverter with the modified 7-level inverter. The modified cascaded multilevel inverter topology can reduce the number of required power switches compared to cascaded multilevel inverter topology. The performance evaluation of the two inverter topologies has been done using MATLAB software and it has been verified experimentally. Simulation result shows the superiority of modified multilevel inverter.
