Abstract

Nowadays, induction motor with different modulation techniques is being used in the industries with better performance. The modulation technique makes induction motor to use it in variable speed application efficiently. In the past, SPWM inverter-based variable speed induction motor has been widely accepted in the industries with satisfactory performance. But, still, industries demanding better performance of the variable speed induction motor with less harmonics in the inverter voltage. This research paper discussed two modulation techniques for induction motor performance comparison purpose first is older sinusoidal modulation technique and second is newly space vector modulation technique. The space vector-based advanced power electronics modulation technique with squirrel cage asynchronous motor is providing better results as compare to sinusoidal modulation technique. Henceforth, advanced power electronics modulation technique will be the better choice for the industries to use asynchronous motor with benefitted performance. Herein paper, the direct torque control scheme is applied together with advanced modulation technique in the efficient way for achieving better results.
