Harmonic Reduction and Performance Improvement of BLDC Motor Using a Selective Harmonic Elimination PWM Based Controller
Objective
The main objective of this project is to reduce the motor current harmonics and their negative effects and also improve the overall performance of the motor by using PWM controller
Abstract
In this paper, a control scheme is proposed which aims to reduce the motor current harmonics and their negative effects and also improve the overall performance of the motor. A DC-DC boost converter fed inverter with Selective Harmonic Elimination based PWM and a passive low pass filter combination is used to reduce the THD, reduce the harmonic copper loss and improve the overall system performance like torque ripples and input power factor. The control scheme also automatically decides between operating conditions where SHEPWM is favorable or not and thus avoids the cases of unnecessary introduction of switching losses.
Keywords: Brushless DC motors, PWM (Pulse Width Modulation), THD (Total Harmonic Distortion).
