Brushless DC Motor Drive System with Reduced DC-Link Capacitor for Reduction in Torque RippleBy Haritha Babu, Binoj Kumar A.C
Abstract: Presence of large value of dc-link capacitance in a brushless DC motor (BLDCM) drive system leads to an increase in the weight and volume of the system. A combination of an IGBT switch along with a small value of DC-link capacitance is proposed in this paper. BLDCM will be supplied by DC-link capacitor and rectified mains supply alternately via DC-link IGBT chopping during the time when the output voltage of …
