Abstract
This paper deals with sensorless brushless DC motor drive fed by a Cuk converter as a cost-effective solution for low-power applications. The single phase supply is fed to uncontrolled bridge rectifier, which is followed by a Cuk converter used to control the voltage of DC link capacitor that feds the Voltage Source Inverter (VSI). Voltage of the DC link capacitor of Cuk converter is controlled to achieve the speed control of BLDC motor. The rotor position sensors are eliminated by using sensorless control. Electronic commutation of the VSI is done by detecting the zero crossing points (ZCP) of the back EMF voltage difference in order to avoid phase delay circuits. A mathematical model of the drive system is simulated with MATLAB/SIMULINK.
