Overview of multi-phase switched reluctance motor drives for electric vehicles

Abstract

Switched reluctance motor (SRM) provide a potential candidate for electric vehicle (EV) applications due to rigid structure, potentially low production cost, the absence of permanent magnets, excellent power-speed characteristics, and high reliability and robustness. This paper aims to review the current research on the design, winding topologies, converter topologies, and control methods of switched reluctance motors (SRMs). Torque ripple and vibration are the main drawbacks of SRMs, which constrain their application. To conquer these drawbacks, multi-phase SRMs (MSRMs), optimum structure, and control methods of SRMs have been utilized over the past decades. In this paper, MSRMs with multiple combinations of stator/rotor poles and winding arrangements are investigated. Different converter topologies are compared, and a full-bridge converter is suitable for SRMs used in EVs. Torque sharing function, direct torque control, and direct instantaneous torque control are the main control methods to reduce the torque ripple of SRMs, which have been comprehensively summarized.

Integration of Switched Reluctance Generator in a Wind Energy Conversion System: An Overview of the State of the Art and Challenges

“…The SRG power converter is related to both the performance and the cost of the system, since numerous research studies have been carried out on the topology of the SRG converter in the WECS to enhance the SRG performance. A general review of several types of power converters is presented in the literature [32]. The conventional SRG power converters in WECS are characterized mainly by providing two stages of voltage for the magnetization or generation of the machine winding.…”

A Direct Energy and Force control (DEFC) for switched reluctance motor

“…These efforts have led to significant improvements in the performance and reliability of the SRM, making it an attractive option for various applications. (Han et al 2019(Han et al , 2021Xu et al 2019Xu et al , 2022Ferková et al 2020;Nandu Krishnan et al 2020;Fang et al 2021;Sun et al 2021;Kotb et al 2022) However, to fully utilize the advantages of SRMs, it is important to have effective control methods that can accurately regulate the motor's torque and speed. There are several methods of controlling SRMs, each with its own advantages and disadvantages.…”
