Generation of Pulse Width Modulation for Controlling BLDC Motor Implementation using FPGA

Abstract

Pulse width modulation (PWM) has been widely used in speed control of BLDC motor drive application. Pulse Width Modulation (PWM) signal is applied to the gate terminal of the power electronic switches IGBT, MOSFET and etc., in the electric drives to control the average voltage delivered to the motor which control the speed of the motor. This PWM pulses generated using Field Programmable Gate Array Xilinx Spartan -3board simulation is done using isim software .output waveforms are obtained and validated with register transfer level (RTL) schematic.
