FPGA Based Controller Drive of BLDC Motor for Electric Vehicle Applications

In Electric Vehicles (EVs), the motor which is employed plays an extremely important role on the comprehensive performance of the vehicle. The authentic control and performance of the vehicle largely depends on the type of the motor and its drive which is used to control the motor. Greater efficiency, high speed range and less noise are the main benefits of Brushless DC motors when compared to other types of electric motors. The objective of this work is to develop a Field Programmable Gate Array (FPGA) based control drive for BLDC motors which can be implemented in electric vehicles. Brushless DC motors are being employed significantly in industrial and automotive applications. Brushless DC motors also require commutation like brushed DC motor, but the main difference is BLDC motors have electronic commutation which increases the efficiency and performance of the motor. FPGA-based motor control drives are used as other options for MCU and DSP. The benefits that FPGAs can offer are the ability to use custom pulse-width modulation (PWM), simple component integration, higher control-loop bandwidth, lesser components and higher dependability. FPGAs also succeed in developing methods which might help in decreasing the losses in both motor and power converter.
