本文提出了一种在每相绕组中带有自耦变压器的开关磁阻电动机（SRM）。新的绕组结构允许快速退磁，从而提高了机器在高速下的性能。在退磁期间，DC总线电压被施加在相绕组的一部分上，并且因此，施加更高的负退磁电压/匝，这导致相激励电流的放电速率的增加。通过有限元分析（FEA）电路模拟的情况下，研究电机验证了所提出的概念。电力电子变换器，可以使用所提出的绕组配置及其相关的控制进行了研究。
In this paper, a switched reluctance motor (SRM) with an auto-transformer like winding in each phase is presented. The new winding structure allows for fast demagnetization, which enhances the machine performance at high speeds. During demagnetization, the DC bus voltage is applied across a portion of the phase winding and accordingly, a higher negative demagnetization voltage/turn is applied, which leads to an increment in the discharge rate for the phase excitation currents. The proposed concept is verified through Finite Element Analysis (FEA) circuit simulations on a case study motor. The power electronic converters that can be used with the proposed winding configuration and its associated control have been investigated.
