Abstract

In this paper, a switched reluctance motor (SRM) with phase windings similar to an auto-transformer is presented. The new winding structure allows for fast demagnetization. This enhances the machine performance at high speeds. During demagnetization, the DC bus voltage is applied across the portion of the phase winding which results in higher negative demagnetization voltage/turn and faster discharge of the phase currents. The power electronic converter configuration is modified to facilitate the new winding topology. The number of switches is kept same as the conventional half-bridge converter used in SRMs. The proposed SRM drive with modified winding configuration is verified through finite element analysis based circuit simulations and experimental results.
