Abstract:

In recent days multilevel inverter(MLI) hold attractive features, in the area of high power medium voltage energy control though multilevel inverter has a number of advantages it has drawbacks in the vein of higher levels because of using more number of semiconductor switches. So in order to overcome this problem the new multilevel inverter is proposed with reduced number of switches. Switch topologies using carrier-based PWM techniques. These pulse width modulating (PWM) techniques include the phase disposition (PD) strategy, alternate phase opposition disposition (APOD) strategy. The modulating indices are evaluated for total harmonic distortion, form factor, crest factor, VRMS (fundamental) and distortion factor. This paper proposed the different carrier arrangement in order find out the less total harmonics distortion. The results are validated using MATLAB/SIMULINK software.
