In this paper, v/f control of Induction motor is simulated for both open loop and closed loop systems. The induction motor (IM) is fed from three phase bridge inverter which is operated with space vector modulation (SVM) Technique. Among the various modulation strategies Space Vector Modulation Technique is the efficient one because it has better spectral performance and output voltage is more closed to sinusoidal. The performance of SVM technique and Sine triangle pulse width modulation (SPWM) technique are compared for   harmonics, THD, dc bus utilization and Output voltage and observed that SVM has better performance. These techniques when applied for speed control   of Induction motor by v/f method for both open loop and closed loop systems it is observed that the induction motor performance is improved with SVM. It is also shown that with the introduction of active filter the performance of IM is further improved for both the cases.
