High Efficiency Operation of Brushless DC Motor Drive Using Optimized Harmonic Minimization Based Switching Technique

Project Code :TEPGED163


The main objective of this project is to eliminate dominant current harmonics, which enables to achieve better BLDCM drive efficiency with minimized losses.


This article presents a new switching technique to minimize losses in a trapezoidal brushless dc motor (BLDCM) drive. Based on the analysis, a pulse width modulation (PWM) strategy with selective harmonics elimination (SHE) is projected for motor phase current for dynamic loss minimization of BLdc motor drive system. The proposed control technique uses SHEPWM to optimize PWM to minimize different losses at different loads and motor speeds based on a predefined look-up table. The efficacy of the control methodology is presented using proper simulation results in MATLAB/Simulink environment.

Index Terms—Brushless dc motor (BLDCM), harmonic analysis, loss minimization, selective harmonic elimination (SHE), switching losses.
