Direct Torque Control of BLDC Drives for Electrical Vehicle Application
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 12
Abstract
Brushless DC (BLDC) motors are commonly used for several industrial applications because of their small size, high torque and high efficiency . This paper presents a Direct torque Control of brushless DC (BLDC) drive by using Hysteresis current control technique to extend the voltage capacity of batteries per charge in electric vehicle applications. In the conventional current control method, the current is still drawn from the batteries even when the motor is turned off. To avoid that leakage current, it is fed to zero crossing detector. By using Hysteresis comparator it produces high switching frequency, which produces ripple torque. But in this technique only current control is possible. The proposed method reduces the Torque ripple by controlling the inverter switching instants and high switching frequency by using direct torque control. The modeling, simulation and control of the BLDC motor is done by using the MATLAB/SIMULINK.
