Abstract :
The novel application of the C-dump power converter topology to the PM brushless DC motor has recently been introduced. The power converter requires a minimum number of devices and is therefore a very attractive choice for the emerging high volume variable speed drive. A comprehensive dynamic analysis of the drive system is necessary before such a product can be introduced to the market. The complete dynamic model of this drive system, along with analysis and experimental verification of key models of operation, are systematically developed and introduced in this paper. Experimental verification is performed on a 4 quadrant 1 horsepower laboratory prototype PM brushless motor drive. The study enables sizing of the required components of the drive system, and estimation of the maximum commutation torque ripple, and hence, the suitability of the drive system for a desired application
