“…A third state, which supplies zero voltage across the phase and, therefore, keeps the flux at a nearly constant level, is optional but important in terms of inverter efficiency and noise reduction. The commonly used inverter topology for SRMs is the asymmetric half bridge [77]. The switching states of the asymmetric half bridge and the resulting voltage loops are shown in Fig.…”

Abstract-Electrical drives are one of the major consumers of electrical energy and their penetration in the market is still growing. Hence, for many drive applications efficient, reliable and cost effective solutions have to be found. Switched reluctance drives (SRD) offer a potential solution when focus is mainly on cost and robustness. However, to benefit from the unique advantages of this machine type a deep understanding of its strongly non-linear behavior is required. After discussing some major differences to classic rotating field machines, this paper presents a broad overview of the state of the art of SRD taking into consideration all aspects relevant to machine modeling, design and control development process. Finally, applications on the market utilizing SRDs and the focus of current research is presented. After reading this paper the reader will be able to assess if this modern drive technology could be advantagous in a given application.

“…One asymmetric half bridge per phase is necessary to control each phase independently from the other phases. To reduce the number of semiconductors and/or wires between inverter and machine different topologies are discussed in literature [77], [78], e.g. the Miller topology and C-dump converter.…”

“…Conventional SRM converters are commercially available, and phase independence and unipolar current are applied widely in industrial applications. Several varieties of converter topologies have been presented in the last 30 years [3]- [6]. With continued research, different topologies have emerged presenting reduced numbers of power switches [18]- [23], faster excitation time [24]- [25], faster demagnetization time [16]- [25], high efficiency [26]-[34], high power factor, and high power [35]- [43].…”

-This paper reviews and analyzes converters for SRM(Switched Reluctance Motor) drive. Conventional classification focuses on the number of power switches and diodes. It is easy to find the number of semiconductors and the cost by counting the number of active components, but it does not show the important characteristics of a power converter. The voltage ratings for the power switches and diodes are also difficult to identify. This paper proposes a switched reluctance (SR) converter configuration that is classified based on the commutation type and magnetic energy path. The converter has three parts: utility interface, front-end circuit, and power converter. Based on the overview on the conventional SR drive, the most important characteristic of the converter is determined by the topology of front-end in conjunction with the power converter. An SR converter has two parts: front-end and power converter. Inasmuch as the capacitive front-end is widely used for voltage source converters, this paper focuses on topologies for the front-end.

“…For example, the mechanical bearing can cause increasing of frictional drag, thermal problem and will be heavy wear in high-speed motor, which not only leads to reduce efficiency of machine and decreases service life of bearings, but also increases burden of maintenance for machine. In addition, lubrication oil cannot be used in high vacuum, ultra high and low temperature atmospheres [2][3].…”

-Novel 8/10 bearingless switched reluctance motor, which can control rotor radial positions with magnetic force, is proposed. The motor has combined characteristics of switched reluctance motor and magnetic bearing. This paper proposes a air-gap control system method of suspending force control in a bearingless switched reluctance motor (BLSRM). The proposed radial force control scheme is independent to the torque winding current. A PI direct current control (DCC) controller and look-up table are used to maintain a constant rotor air-gap. From the analysis and the experimental results, it is shown that the proposed strategy is effective in realizing a naturally decoupled radial force control of BLSRM.
