This paper present a DSP based V/f open loop and close loop induction motor AC drive with SVPWM modulating scheme. This paper describes comparison of SVPWM and SPWM modulating techniques with motor load and choke load. Simulation results are obtained using PSIM Software with a 45kW (60 HP) motor drive and analysis of THD (Total Harmonic Distortion) and FFT (Fast Fourier Transform) in Line Voltage and Line Current for both modulating techniques. From results it is concluded that SVPWM can utilize more dc link voltage than SPWM and we get more output voltage. In SVPWM THD in line voltage & line current is also less than SPWM. Also this paper describes V/f open loop and close loop induction motor control techniques with SVPWM modulating scheme for controlling of three phase induction motor drive and getting constant flux/torque upto rated speed. Simulation results are obtained using PSIM Software with a 5.5kW (7 HP) motor drive and analysis of motor speed, motor voltage, motor current, THD and FFT (in Line Voltage and Line Current) and motor torque. The principle is explained qualitatively and extensive experiments have been carried out to verify and validate the proposed algorithm. A floating-point C2000 family DSP 28335 from Texas Instruments was used as the controller to implement the proposed control algorithm.
