A Voltage Controlled Permanent Magnet Brushless DC Motor Using SEPIC PFC Converter

K. Kandasamy, Dr.M. Rajaram

Abstract


This dissertation discusses about the application of a SEPIC DC-DC converter for a permanent magnet brushless DC motor (PMBLDCM) drive, run by single phase AC mains as single stage power factor correction fed through double bridge rectifier. A three phase voltage source inverter is used as an electronic commutator to operate the permanent magnet brushless DC motor. The advantage of these motors is the removal of brushes, leading to eliminate many problems associated with brushes. The scope of this project is in the use of PMBLDC motor as a drive for the compressor of air- conditioners, fans etc. The switch control separates the two procedures, adjustment of SEPIC converter, and regulation of speed can respond immediately during transient commutation and robustness can be improved and thereby the performance. The proposed permanent magnet brushless DC motor drive is designed and modeled, and its performance is evaluated in MATLAB- SIMULINK.
