Switched reluctance motors (SRMs) can provide an attractive traction drive for electric vehicle applications. To lower the investment in the off‐board charging station facilities, a multi‐functional switched reluctance motor topology is proposed on the basis of the traditional asymmetrical half‐bridge converter. The SRM phase windings are employed as input filter inductors and centre‐tapped windings are also developed to form symmetrical inductors for three‐phase grid supply. Owing to the varying rotor position, phase inductors are unequal between one another. A hysteresis control scheme is therefore developed for grid‐connection operation. In addition to AC supplies, the proposed topology can also supports the DC‐source charging. A new current sharing strategy is employed to diminish the influence of the unequal winding inductances. The simulation and experimental tests are carried out to verify the proposed topology and control methods. Since this work eliminates the need for building charging station infrastructure, its potential economic impact on the automotive market can be significant.
