The FPGA programme was carried out using hardware description language VHDL and Xilinx-ISE 9.2i design software. The proposed control schemes have been realized and implemented on the Spartan-3E Starter kit. The FPGA is used to generate the appropriate PWM signals for the inverter switches.
The inverter is employed as a Voltage Source Inverter (VSI). The control is achieved via varying the stator voltage, and varying the stator voltage and frequency with V/F control method. This thesis presents a design and practical implementation of a Field Programmable Gate Array (FPGA) based Sinusoidal Pulse Width Modulation (SPWM) for a three-phase inverter to control the speed of a three-phase Induction Motor (IM).
