FPGA Implementation of Space Vector PWM Technique for Voltage Source Inverter Fed Induction Motor Drive

This paper presents implementation of space vector pulse width modulation (SVPWM) technique for three phase voltage source inverter (VSI) using field programmable gate array (FPGA). Variable voltage and frequency supply to ac drives is invariably obtained from a three phase voltage source inverter. A number of pulse width modulation 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. There is an increasing trend of using space vector PWM because of their easier digital realization and better dc bus utilization. Both simulation and experimental results are presented.
