Abstract
Multilevel inverters allow a higher count of voltage levels with lower harmonics and without transformers or synchronized switching devices connected in series. This work analyzes the harmonics and total harmonic distortion on multilevel inverters. In this study, the multilevel arrangement uses a CHB inverter. III, V, VII, IX, XI and XIII level CHB inverter output harmonics and THD are investigated and compared with the help of MATLAB simulation. And output voltage is being analyzed using the Fourier series. It is found that the total harmonics distortion and harmonics are suppressed using higher levels of CHB multilevel inverter architectures.
Keywords Multilevel Inverter (MLI), Total Harmonic Distortion (THD), Cascaded, Harmonics, Cascaded H Bridge (CHB).
