Realization of cascaded multilevel inverter

In this paper, a cascaded multilevel inverter is implemented for resistive as well as RL load. Working of Cascaded multilevel inverter is studied for various levels of voltages by implementing proper switching. To verify the operation of the proposed inverter, simulation is completed using MATLAB for various levels of outputs such as nine, eleven, fifteen, twenty seven, thirty three and thirty nine levels. Further, the simulated proposed system is analyzed in terms of total harmonic distortion for resistive and RL load. The results are obtained successfully and presented in the following pages.
