Development of Buck Switch Mode Rectifier Charger for Battery Powered Switched Reluctance Motor Drive

S.Dhatchayani, B.Barathy, A.Kavitha

This paper presents the development of a compact battery-powered switched-reluctance motor (SRM) drive for an electric vehicle application. In motoring mode, the proposed front-end converter can be operated as a DC/DC boost converter to establish well-regulated and boosted DC-link voltage for SRM drive from battery. In idle charging mode, the proposed front-end converter is arranged to act as a buck-type switchmode rectifier (SMR) for charging the battery with good line power quality. Four diodes embedded in the SRM converter and the two motor phase winding inductances are employed to form the necessary constituted components of the SMR.
