At present, induction motors are the dominant drives in various industries. It is quite cumbersome to control an induction motor (IM) because of its poor dynamic response in comparison to the DC motor drives. A Voltage Source Inverter (VSI), it is possible to control directly the stator flux linkage and the electromagnetic torque by the optimum selection of inverter switching vectors. The modeling of an IM drive employing V/F method with application of Space Vector Pulse Width Modulation (SVPWM) is performed in this article, it is better to understand the V/F method and its difficulties. By using 3-level inverter, ripples in speed and torque will reduce. The reference voltage vector is then realized using a voltage vector modulator. The extensive simulation results are presented based on case studies.
