“…The R-Dump topology, represented in Figure 13, has one switch per phase and can only operate in hard-switching mode with two operating modes (magnetization and demagnetization) [53][54][55][56]. The main advantages of this topology are the simple structure, the low number of power devices and the low cost.…”

The use of power electronic converters is essential for the operation of Switched Reluctance Machines (SRMs). Many topologies and structures have been developed over the last years considering several specific applications for this kind of machine, improving the control strategies, performance range, fault-tolerant operation, among other aspects. Thus, due to the great importance of power electronic converters in such applications, this paper is focused on a detailed review of main structures and topologies for SRM drives. The proposed study is not limited to the classic two-level power converters topologies dedicated to the SRMs; it also presents a review about recent approaches, such as multilevel topologies and based on impedance source network. Moreover, this review is also focused on a new class of topologies associated to these machines, namely the ones with fault-tolerant capability. This new category of topologies has been a topic of research in recent years, being currently considered an area of great interest for future research work. An analysis, taking into consideration the main features of each structure and topology, was addressed in this review. A classification and comparison of the several structures and topologies for each kind of converter, considering modularity, boost capability, number of necessary switches and phases, integration in the machine design, control complexity, available voltage levels and fault-tolerant capability to different failure modes, is also presented. In this way, this review also includes a description of the presented solutions taking into consideration the reliability of the SRM drive.

“…Compared to other converter topologies, the benefits of this topology are its simplicity and the independent phase control with a maximum degree of freedom, but the drawbacks are the non‐conventional structure from other AC motor drives, as discussed in the literature 23,24 . Note that, the proposed fault diagnosis method is totally independent of any converter topology that can excite all individual phases simultaneously.…”

Summary In this study, an active fault diagnosis of a switched reluctance motor (SRM) using a sliding mode observer (SMO) and an average torque estimator for light electric vehicle (LEV) is proposed. The residual based fault detection using the SMO is used to diagnose a fault in a position sensor. When the fault is diagnosed, the corrupted sensor outputs are detected and then substituted with the estimated speed and position signals for sensorless operation in the sensor fault‐tolerance mode. Moreover, all possible stator winding faults are monitored and can be diagnosed using an average torque estimation as soon as the completion of one electric cycle. The parameter uncertainties in the motor model are considered and analyzed for robustness of the operation. Therefore, any deviation of the actual system parameters from the estimated parameters can be effectively detected and diagnosing a type of fault in a sensor or stator windings. Finally, to illustrate the applications of the proposed scheme, simulation studies of several fault scenarios are discussed and conducted for a 3.5 kW 6/4 three‐phase SRM.

Typically, a geared drive system is used to connect an induction motor of 1500 rpm with a Raymond Pulverizer of 105 rpm in mining applications. This system suffers from low efficiency and a heavy motor drive. This paper proposes a novel design of a 75 kW, 72/48 switched reluctance motor (SRM) for a low-speed direct-drive as for mining applications. The paper is focused on the design and comparative evaluation of the proposed machine in order to replace a geared drive system whilst providing a high torque low-speed and direct-drive solution. The machine performance is studied and the switching angle configuration of the machine is also optimised. The efficiency of the whole drive system is found to be as high as 90.19%, whereas the geared induction motor drive provides only an efficiency of 59.32% under similar operating conditions. An SRM prototype was built and experimentally tested. Simulation and experimental results show that the drive system has better performance to substitute the induction motor option in mining applications.
