Optimization of low voltage synchronous reluctance machines using different modulation schemes

This paper presents different possibilities to increase the efficiency and operating range of synchronous reluctance machines in low-voltage traction applications. The maximum power is defined based on the limit of the maximum DC-link voltage level. By using different modulation and control schemes, it is possible to optimize the complete drive train. Moreover, the control schemes will be presented with flow diagrams. Finally, the theory will be approved based on the dynamic and static measurement results.
