Brushless DC motor drive with power factor correction controller technique

In this paper we have proposed a power factor correction technique for permanent magnet brushless DC motor (PMBLDCM) drive. The proposed method improves the power quality of the system by reducing the harmonic contains in current source i.e. total harmonic distortion (THD) in the system. As THD get reduce of the system, the power factor of the system get improved and archived near to unity. To improve power factor of the system it is necessary to bring source current in phase with source voltage, which can be done by the boost converter. PMBLDC motors are best because of their high efficiency, silent operation, compact size, high reliability, and low maintenance requirements. The performance of the proposed system is simulated in MATLAB/Simulink environment.
