The induction machines are widely used in a wide variety of applications. The dynamic simulation is one of the key steps in the validation of the design process of the motor drive system, which eliminates the designing mistakes and the resulting errors in the prototype construction and testing. Variable voltage and frequency supply to ac drives is invariably obtained from a three-phase voltage source inverter (VSI). A number of Pulse width modulation (PWM) scheme is used to obtain variable voltage and frequency supply. The most widely used PWM schemes for three-phase VSI are carrier-based sinusoidal PWM and space vector PWM (SVPWM). There is an increasing trend of using space vector PWM (SVPWM) because of their easier digital realisation and better dc bus utilisation. Firstly model of a three-phase VSI is discussed based on space vector representation. And the simulation model of SVPWM inverter is obtained using MATLAB/SIMULINK. The prototype of 3 phase SVPWM bridge inverter is setup and gate pulses are obtained from Arduino Mega2560. Also this paper presents MATLAB /SIMULINK implementation of an induction machine using dq0 axis transformations of the stator and rotor variables in the arbitrary reference frame.
