The current generation of variable speed drives is typically based around the real-time digital generation of Pulse-Width Modulated (PWM) waveforms using either microprocessors or application-specific integrated circuits in many ways. PWM generation techniques for getting the control of inverters have the major advantages that component drift and tolerance problems associated with earlier analog implementations. Of all the various PWM techniques Sinusoidal and Space vector PWM techniques are more prominent. The implementation of these techniques through Matrix Laboratory (MATLAB) simulation is discussed in this paper. The Space Vector technique is essentially based around the decomposition of a reference voltage vector into voltage vectors realizable on a six pulse inverter although as it will be shown, space vector modulation is actually a special case for the Sinusoidal PWM technique. A Two-level inverter is being used for the space control of a 3-phase Induction Motor. The Two control strategies, namely, Sinusoidal Pulse Width Modulation and Space Vector Modulation are to be employed for the V/F control in order to have the control on speed and torque. A comparison is presented on the performance of a 3-phase Induction Motor, between sinusoidal PWM technique and space vector PWM technique. These aspects of space vector modulation are discussed in this paper to illustrate their practical engineering significance. The MATLAB Simulator is employed for the simulation and analysis work.
