Simulation of Multilevel Inverter Fed Induction Motor Drive

Abstract

The ruggedness, dependability, and economy of induction motors make them a popular choice in the industrial sector. Induction motor drive necessitates the use of appropriate converters in order to achieve the required speed and torque with minimal or no ripples. Multilevel inverter technology has recently emerged as a very important alternative in the areas of high power medium-voltage control as well as for improving total harmonic distortion by reducing the harmonics, both of which are important considerations. Most of the time, the poor quality of voltage and current produced by a conventional inverter fed induction machine is due to the presence of harmonics, which results in a significant amount of energy being wasted. In MATLAB, the simulation results of the proposed topology three phase 33-level multilevel inverter fed induction motor drive are verified against the real-world results.
