“…A main reason is that SRMs are conventionally driven by a rectangular winding current, which is generated by the asymmetric H-bridge (AHB) power converter [3]. With this type of driving method, there is only one or two phases windings that are energized at the same time [4] [5], as a result, the winding current commutation is not smooth enough, which contributes to the noise and torque ripple. This also explains why the switched reluctance motors are rarely used in electric vehicles currently.…”

In order to reduce the torque ripple of a switched reluctance motor in the electric vehicles, a space vector pulse width modulation (SVPWM) driving method for the switched reluctance motor (SRM) is proposed. With a ring structure, a three-phase SRM can be driven by using a standard fullbridge power converter instead of the conventional asymmetric H-bridge. Based on this type of driving topology, an SVPWM method is applied for driving the SRM. The SVPWM method is compared to the conventional SRM driving method by using the asymmetric H-bridge, the results show that the SVPWM can reduce the torque ripple in the SRM effectively. The experimental validation is also made to verify the proposed driving topology and method, of which the results match well with the simulated results.

Accurate real-time rotor position is indispensable for switched reluctance motors (SRM) speed and torque control. Traditional position sensors add complexity and potential failure risk to the system. Owing to the added advantages of high stability and low cost, the position sensorless method of SRMs has been extensively studied to advance its use in vehicles and construction machinery. This paper presents an overview of position sensorless control techniques from the perspective of whether the method requires the establishment of complex mathematical models. Various types of methods are compared for performance, such as speed regulation range, algorithm complexity, and requirement of the pre-stored parameter. A discussion is presented concerning current trends in technological development, which will facilitate the research addressing potentially effective methods for position estimation in SRM drive systems.
