Due to less consumption of energy and environmental pollution, electric vehicles (EV) have obtaining attention from everywhere the world especially in automobile industry. Nowadays, Induction motor drives are the most appropriate drive for automobile industries to realize the most effective performance. For variable speed applications of Industrial Drives, Induction motors are widely used. The drives used for electric vehicle applications conventionally fed by the voltage source inverter. The two speed control schemes for the induction motor are scalar control and vector control schemes. In ancient time, the motors used for electric vehicle applications is DC motor drives. Implementation of vector control scheme enhanced the performance of electric drives especially it gives a high performance in the drive system. In view of response time and efficiency, scalar control scheme is inferior to modern Vector control schemes, but it requires lesser hardware resources and thus reducing the cost. The decoupling of flux and torque producing component gives high performance in the drive system. The stator current components are decoupled and can control separately. This paper discuss on investigating the closed loop system of voltage source inverter (VSI) fed Induction Motor Drive with scalar method and Vector method has been analyzed and compared. A Sine Pulse Width Modulation (SPWM) technique is used to control the switching action in the drive system. Two decoupled components is controlled by PI controller included in this closed loop system. MATLAB/Simulink has been used to simulate and validate the results. Comparative evaluation of two control schemes have been plotted and analyzed.
