A Power Factor Corrector DC-DC Buck-Boost Converter fed BLDC Motor
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 1
Abstract
This paper proposes a buck-boost converter, controlling scheme with reduced number of switches in inverter and design of power factor controller for Brushless DC motor. BLDC motors are the most recent choice of researchers, for their high efficiency, silent operation, high reliability and low maintenance requirements. The proposed Power Factor Controller topology improves Power Quality by improving performance of BLDCM drive such as reducing the current harmonics at AC mains near to unity power factor according to the IEC 61000-3-2 standard. PFC converter requests the drive to draw sinusoidal supply current in phase with the supply voltage. The position sensors used in BLDC drives have drawbacks of additional cost, mechanical alignment problems. These bottle necks results in sensorless technique. The voltage or speed controllers can be realized using proportional integral and Derivative (PID) controller. The proposed drive is simulated in MATLAB/Simulink, the obtained results are validated.
