“…These topologies were proposed to be used in electric vehicles and also in pumping systems associated to renewable sources such as PVs. A topology with a modified quasi-Z source converter was proposed with the objective to decouple the magnetizing and demagnetizing port [78]. As shown in Figure 20, the magnetizing port is connected to the capacitor C1 of the quasi-Z network while the output terminal of this network is connected to the demagnetizing port.…”

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.

“…Also, the PF value of the grid side current is low in both of them. In [4]- [7], four different converters are used as front-end converter in the SRM drive system. Separation of the magnetization and demagnetization terminals is done through the usage of Modified Quasi Z-source Converter (MQZSC) as front-end converter in [4].…”

In this paper, a Switched Reluctance Motor (SRM) drive system is proposed to make a trade-off between torque profile and vibration amplitude. In the proposed drive system, the power factor correction and fast demagnetization are achieved using a single-phase Vienna rectifier as a front-end converter for SRMs with a nominal voltage equal to half DC-link voltage. The three-level Vienna rectifier provides doubled negative voltage in demagnetization, resulting in a shorter current tail and faster demagnetization. But, Applying higher voltage in demagnetization has a negative impact on the vibration amplitude at the point of demagnetization. Therefore, a control algorithm is designed to apply a negative modulated voltage to the motor phase, with a minimum change rate at the beginning of demagnetization and a linear average during the demagnetization interval. Accordingly, the mitigation of the vibration occurring at the commutation point and prevention of negative torque are simultaneously achieved over a wide speed range. The simulation and experimental results demonstrate the proposed drive system's positive effect on the vibration amplitude, grid side current quality, and SRM performance in a wide range of speed variations.

“…In [26], a modified quasi Z-source converter in front of an asymmetric half-bridge converter for the switched reluctance motor is proposed, the quasi Z-source converter not only improves the speed regulation performance of the drive system and reduces the torque ripple by adjusting DC bus voltage according to the operation condition but also reduces total harmonic distortion and improves the power factor by the peak current control.…”

“…In [27], a power factor correction converter composed by two cuk circuits with a communal switch fed switched reluctance motor is proposed, the modified cuk converter reduces torque ripples by adjusting DC bus voltage according to speed, and at the same time, it improved the power factor in wide speed range. e authors of [26,27] reduce the torque ripples of the SRM and increase the power factor preferably through the DC converter, but its structure and implementation is relatively complicated. A fine solution for torque ripple suppression of the SRM is to feed the motor with low voltage in the low speed range and to increase voltage accordingly when the speed increases.…”

The switched reluctance motor (SRM) suffers the main drawback of torque ripples, and a buck converter-fed SRM motor drive has been proposed to suppress torque ripples and correct a power factor in this paper. The buck converter reduces the torque ripple by supplying appropriate DC-link voltage; meanwhile, the buck converter realizes a function of power factor correction at AC mains. An enhanced performance has been obtained on speed control and power quality improvement. An experimental SRM motor drive is formed, and the experimental results show that the proposed drive possesses an improved function with suppression of torque ripples and power factor correction.
