Abstract—Three phase induction motors are representing one of electrical machines is widely used in industrial application, there are many methods to control speed of induction motor. Such as changing the number of stator poles, controlling supply voltage etc. The varying voltage and frequency of three phase supply is a modern method of speed control. In this method can a large amount of energy saving to do so using VFD, the power electronic inverter is a main part of a variable frequency drive. In this paper proposed the simulation of inverter with three types of space vector pulse width modulation SVPWM technique. It is modern and it became a popular PWM for voltage source inverter VSI, the model having advantages for easy control, low cost and achieved to satisfy the requirements of the user. The model is a simulation and analyzed using (SimPower in MATLAB/SIMULINK) environment. The purpose of this paper is to analyze, comparison, and study a three-phase induction motor drive using three types of SVPWM. The simulation results which illustrate the performance of SVPWM system were plotted and discussed. These results are shown variable speed tracking of SGI squirrel cage induction motor, with large scale industrial mechanic load.
