Power Factor Correction And Power Quality Improvement in BLDC Motor Drive Using Sepic Converter

This project design SEPIC DC-DC converter feeding a BLDC motor drive as a cost effective solution for low power applications. In proposed circuit the single phase supply is fed to uncontrolled bridge rectifier. The output of bridge rectifier is fed to a Sepic DC-DC converter which is used to control the voltage of DC link capacitor which feds the Voltage Source Inverter. The BLDC motor is fed from Voltage Source Inverter. Voltage of a DC link capacitor of SEPIC converter is controlled to achieve the speed control of BLDC motor. A MATLAB Simulation will used to simulate the developed model to achieve a wide range of speed control.
