Low-Voltage Switched Reluctance Machine Based Traction Systems for Lightly Hybridized Vehicles 2001-01-2507

This paper presents that low-voltage (42V) current intensive Switched Reluctance Machine (SRM) based traction systems are feasible for lightly hybridized vehicles. Power electronic drive as well as electric machine issues are comprehensively addressed. Five different SRM drivers for low-voltage and high-voltage machines are studied. Suitability of the proposed low-voltage, high-current drives is elaborated. Furthermore, four machines with the rating of 7.5 kW are designed and simulated. These traction machines have 6/4 and 8/6 SRM configurations with the operating voltage of 42V and 300V. Higher torque density is the main advantage of the low-voltage machines compared to the high-voltage machines. In addition, 6/4 SRMs have better performance.
