4. ABSTRACT
This paper deals with a power factor correction (PFC)-based Cuk converter-fed
brushless dc motor (BLDC) drive as 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. 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 and a hardware prototype of
the proposed drive is developed to validate its performance over a wide range of speed with
unity power factor at ac mains.
