Abstract

In this paper, two control strategies for BLDC motor drive have been implemented. One of the control strategies is based on PFC-CUK converter fed PMBLDCM drive and another one is PFC-interleaved boost converter fed BLDC motor drive. Comparison has been made between the two control strategies in terms of Torque ripple, Power factor for different operating speeds. The proposed work has been implemented under MATLAB/simulink environment. Simulation results are presented to validate proposed work. From the results, it is observed that PFC interleaved Boost converter fed BLDC motor drive is more effective compared to CUK converter fed BLDC motor drive.
