| Abstract |
Electric drives based on a switched reluctance motor (SRM) have some attractive properties: the drives have a high efficiency especially at partial load and switched reluctance motors are less expensive than AC induction motors. Nevertheless, there are some
disadvantages like noise and torque ripple caused by the physical working principle of the SRM.
With the implementation of a switched reluctance drive (SRD) in an electric vehicle, the suitability of a SRM for traction should be examined. Therefore, a water-cooled power converter with the control-unit and the peripheral devices will be developed. This paper
presents the structure and the function of the power converter, the control procedure to balance the switching-losses in the modules, differrent practical realizations and the final
realization for the water-cooled power converter with especially designed power modules. |
