Abstract
Most of the applications in industries require medium and high voltage so hence multilevel inverters (MLI) are gaining significant importance [1]. This paper gives an insight of different modulation strategies such as phase shift, level shift used for single phase five level cascaded H-bridge (CHB) MLI for reducing total harmonic distortions with high-power handling capability by increasing its voltage level. Also, emphasis more on multicarrier PWM strategy for the CHB MLI. A simulation model of five level cascaded H-bridge multilevel inverter is developed using MATLAB/SIMULINK and its total harmonic distortions has been analyzed.
