A Modern Design of Torque Ripples Reduction in BLDC Drive for Electric Vehicle Application
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 11
Abstract
BLDC motors are one of the motor type’s fast gaining the interest of the researchers. This motor attracts to a great extent concern due to its better speed, high dynamic response, high efficiency, long operating life, noiseless operation and power density, compactness, high torque potential for steep slope or road conditions, high reliability, robustness for electric vehicle and offers a reasonable cost. This paper presents a minimization of torque ripples in brushless DC (BLDC) drive by using Hysteresis Current Limiting technique to extend the lifetime 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 which results it reduces the life time of the battery by continuous leakage current from the battery. To avoid that leakage current it is fed to zero crossing detector here the leakage current is controlled by using Hysteresis comparator but it produces high switching frequency which produces ripples in torque. In this technique only current control is possible but the ripples are caused by hysteresis control and inverter switching intervals. The proposed method controls the inverter switching intervals and high switching frequency by using DC to DC Converter which minimizes the Torque Ripples. The simulation and control of the BLDC motor is done by using the MATLAB/SIMULINK.
