Low-cost battery-powered switched reluctance drives with integral battery-charging capability

This paper presents a low-cost battery-powered drive using switched relucta nce motors. The converter topology proposed in this paper is cost effective while still maintaining an energy-efficient system for battery-powered dri ves, The proposed drive not only achieves cost-effective and efficient batt ery motoring, but also battery charging with minimal additional power semic onductor components. Charging is achieved through the windings of the switc hed reluctance motor, thus eliminating the need of external bulky transform ers and separate charging units.
