Multilevel inverters are gaining more importance nowadays due to reduced total harmonic distortion (THD) and improved quality of output waveform. As the output voltage level increases, output harmonic content of such inverters decreases, allowing the use of smaller output filters. These multilevel inverters are used for high power applications and also in photovoltaic systems. This paper proposed the simulation models of various five level and seven level inverters. A comparative study based on various parameters like THD, device count, gain etc. are also performed. The simulation is done using MATLAB/Simulink software. The simulation results shows that the enhanced five level and enhanced seven level inverters gives better performance in terms of THD, gain etc. Also the hardware prototype of enhanced five level inverter is implemented.
