Abstract: A Brushless dc motor (BLDC) drive fed by a Cuk converter with power factor correction at ac mains is a cost-effective solution for low-power applications. The speed of the BLDC motor is controlled by varying the dc-bus voltage of a voltage source inverter (VSI) which uses a low-frequency switching of VSI (electronic commutation of the BLDC motor) for low switching losses. Speed controllers for sensorless BLDC motor use the principle of Back EMF for finding out the commutation instance. A diode bridge rectifier followed by a Cuk converter working in a discontinuous conduction mode (DCM) is used for control of dc-link voltage with unity power factor at ac mains. Performance of the PFC Cuk converter is evaluated under four different operating conditions of discontinuous and continuous conduction modes (CCM) and a comparison is made to select a best-suited mode of operation. The performance of the proposed system is simulated in a MATLAB/ Simulink environment.
