The effort is taken for this performance improvement without making any changes in the material of the multi-level inverter. Multi-level inverter performance depends on pulse width modulation technique adopted in it. The proposed techniques have the characteristics of exhibiting less total harmonic distortion. The output voltage is also improved. In this paper, these proposed techniques are applied to multi-level inverter and the performances are evaluated. It is simulated in MATLAB/Simulink and the results are obtained. The results are compared with the conventional method to look into its validity.

INTRODUCTION At present the power electronics technology is becoming prosperous in electrical and electronics-oriented engineering field. Its applications are finding more places in the field of engineering [9]. Multi-level inverter (MLI) is a next generation of inverter. It is superior than inverter. MLI is the power electronic device which is made up of semiconductor material. More
