Switched Reluctance Machine Drives for electrical vehicle propulsion - optimal control with regard to the losses in machine and converter

This paper deals with the losses of Switched Reluctance Machine Drives (SRDs) for electric vehicle propulsion, consisting of the losses in the Switched Reluctance Machine (SRM) and the converter, across some operating regions based on different control strategies, namely Firing Angle (FA) control and Torque Sharing Function (TSF) control. The SRM model which takes into account copper losses and converter losses is obtained through MATLAB/Simulink. The losses and efficiencies in the machine, the converter and the SRD as function of speed and average torque are compared for a 30 kW peak 8/6 SRD.
