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

This paper presents a low-cost battery-powered drive using switched reluctance motors. The converter topology proposed in this paper is cost effective while still maintaining an energy-efficient system for battery-powered drives. The proposed drive not only achieves cost-effective and efficient battery motoring, but also battery charging with minimal additional power semiconductor components. Charging is achieved through the windings of the switched reluctance motor, thus eliminating the need of external bulky transformers and separate charging units.
