Harmonic Analysis Of Multilevel Inverter

This paper present the different levels of cascaded H-bridge inverters and the minimization of total harmonic distortion by increasing levels. Selective Harmonic Elimination technique is used as a switching scheme. The analysis of three, five and seven level cascaded H-bridge inverter simulation work is done by using the MATLAB software and experimental results have been presented to validate the theory. The simulation results show the improvement of output voltage waveform and reduction of the THD by increasing the levels in inverter.
