Abstract: Three phase induction motor is controlled using three phase sinusoidal FPGA controller with constant V/F ratio. The controller is designed in a single integrated circuit to control both voltage and frequency simultaneously. The single control IC is implemented using FPGA and controller outputs like voltage, frequency are controlled by clock frequency. Single edge sinusoidal PWM technology is proposed for this controller and it operates up to 2 kHz of fundamental frequency and 30 kHz of switching frequency. Delay time is provided for inverter switches to avoid shoot through fault in the inverter legs. IGBT switches are used in inverters for variable voltage variable frequency drives and switching power supplies. Dead time for the IGBT switches is adjustable. FPGA controller is used to generate Sinusoidal Pulse Width Modulation signal to operate induction motor at variable voltage and variable frequency.
