PERFORMANCE OF VOLTAGE SOURCE MULTILEVEL INVERTER - FED INDUCTION MOTOR DRIVE USING SIMULINK

This paper deals with performance of voltage source multilevel inverter-fed induction motor drive. A Voltage source inverter (VSI) is compared with multilevel inverter. A conventional Voltage Source Inverter-fed induction motor drive is modelled and simulated using matlab simulink and the results are presented. Multilevel inverter employing Selective Harmonic Elimination (SHE) method is also simulated and the corresponding results are presented. The FFT spectrum for the outputs is analyzed to study the reduction in harmonics.
