Abstract: The construction of a Cascaded H-bridge multilevel inverter is done by connecting a set of single full bridge inverter in series. An attempt is made to perform a detailed analysis on five-level Cascaded H-bridge Multilevel Inverter (CHMLI)utilizing three modulation techniques namely Equal Phaseshift method,Phase opposition disposition method,Alternate Phase Opposition disposition method.The Total Harmonic Distortion (THD) % and circuits complexity of the three PWM techniques were compared using MATLAB/SIMULINK software.
