Design and Implementation of Sensor-Based Trapezoidal Control of BLDC Motor Based on XMC-7200 Microcontroller for EV Application

Abstract

Nowadays with the exponential growth in technology efficiency is a very critical aspect of any electrical drive system. Using BLDC motors in place of conventional AC induction motors and brushed DC motors can improve efficiency and save energy. In this paper implementation of speed control of brushless DC motor using hall effect sensors with PI controller using XMC 7200 MCU for electric vehicle-type application has been proposed. Block commutation or six-step commutation or trapezoidal control technique is used for the commutation of the phases. This method is straightforward and cost-effective from the implementation of a hardware point of view. A simulation study and hardware implementation have been carried out for this scheme.
