Investigation of transient performance of VSI-Fed IM drives using Volts/Hz and vector control techniques

This paper has been attempt to presents the investigation of transient performance of Voltage Source Inverter (VSI)-fed induction motor drives using vector and volts/Hz control techniques. In general, the principle of operating a three phase induction motor indicates that the speed of the motor is directly related to the frequency of the supply. The voltage source inverter fed induction motor drives are increasingly applied in many recent industrial applications that require superior transient performance. Recently, developments in power electronics and semiconductor technology have lead improvements in power electronic systems. Hence, different circuit configurations namely multilevel inverters have become popular and considerable interest by researcher are given on them. Variable voltage and frequency supply to AC drives is invariably obtained from a three-phase voltage source inverter. There is an increasing trend of using Space Vector PWM (SVPWM) because of their easier digital realization and better DC bus utilization features. Simulation results and discussions regarding with SIMULINK model of investigation of transient performance of Voltage Source Inverter (VSI)-fed induction motor drives using vector and volts/Hz control techniques are obtained using MATLAB/SIMULINK environments for effectiveness of the proposed technique.
