This paper investigates the efficacy of V/f scalar control for a three-phase squirrel cage induction motor (IM) integrated with a proportional-integral (PI) controller and MOSFET-based inverter. The key objective is to achieve robust speed regulation and stability under varying load disturbances. In the present work, two control schemes have been delved (a) the closed-loop approach, offering superior performance but less common in industrial settings, and (b) the widely employed open-loop method. Leveraging MATLAB/Simulink, simulations have been performed to compare the performance of three-level and five-level inverter configurations. To quantify the harmonic content, a comprehensive analysis of total harmonic distortion (THD) has been conducted. The study further incorporates the concept of electric vehicles (EVs), exploring how the proposed control strategy could enhance the performance and efficiency of EV drives.
