Abstract :
Multi level inverters MLI are used in places or industries that require very high voltage and huge current. Multi level inverter topologies have various advantages over single level converters. These advantages are like rise in output voltage, reduction in the total harmonic distortion THD , reduction in electro magnetic interference EMI generation etc. Key attribute of a multi level inverter is the reduction in the voltage stress on each power device. This reduction is due to the use of several levels available on the DC bus. The dawn of multi level inverter topologies have created requirement of various pulse width modulation techniques. In this paper authors have used PWM technique, by which the total harmonic distortion of the multi level inverter is decreased. In this we have also controlled the speed of the induction motor by supplying the power through a multi level inverter.
