Four-quadrant control of C-dump converter-fed PMBDC motor drive system

This paper presents the operational and design characteristics of the C-dump converter-fed permanent-magnet brushless DC motor (PMBDCM) drive for four-quadrant performance. The C-dump converter, which has one switch per phase, is present for use in the control of a PMBDCM. The drive system is analyzed and design guidelines to develop for the given PMBDCM ratings. The input power factor correction (PFC) is applied to the developed C-dump converter-fed PMBDCM drive. Experimental results from a laboratory prototype are presented to validate the feasibility of the proposed PMBDCM drive system. The predicted and measured overall system efficiencies are presented with and without PFC circuit.
