Multi-level inverters (MLI) are used widely in the recent years for high speed applications. Whenever high output is required to drive adjustable speed drives and certain variable speed drives, multi-level inverters are incorporated in the circuit. This paper presents MATLAB/SIMULINK models of five level, seven level and nine level inverter topologies. Cascaded H bridge topology is chosen for analysis. Five, seven and nine level inverter topologies are compared and output voltages are recorded. Further, total harmonic distortion THD is calculated for these topologies and results are tabulated. Total harmonic distortion comparison is done using data visualization tool to visually depict and understand there is a reduction in total harmonics with the increase in levels of the inverter.
