Abstract :This paper presents the analysis of Power Factor Improvement (PFI) and speed control of (Brushless) BLDC motor drive using Power Factor Improvement – Canonical switching Cell (PFI-CSC) converter. The proposed PFI-CSC converter is used to achieve unity power factor by closed loop control of the BLDC motor drive. The speed control is achieved by varying the dc link voltage of the proposed converter through closed loop control of the BLDC motor drive. The proposed converter eliminates the rectifier bridge thereby reduces the conduction losses. The performance of the proposed PFI-CSC converter for BLDC motor drive is improved by power factor correction and speed control of the BLDC motor. The Power Quality is maintained in AC mains for wide range of speed control. The performance analysis of the BLDC motor drive is carried out using the proposed converter with and without closed loop control through MATLAB simulink. The operating principle, simulation results and comparative analysis of the proposed converter BLDC motor drive are presented in this paper.
