“…Reduction of the source current ripple results also in lower dc-link voltage ripple. The paper [13] proposes an algorithm to reduce dc-link voltage ripple. However, specific cases considered in the above-quoted paper did not include motor control with overlapping intervals of conduction periods of individual phases.…”

Abstract. This paper presents a proposal of a new control method of the switched reluctance motor (SRM) in the low-speed range. The proposed method limits the maximum value of SRM drive supply current. The application of this method results also in improvement of the drive efficiency compared to the classical current control method, so it can be applied to control switched reluctance motors designed to the electric vehicles drive. The method may be effective especially in congested traffic. Nowadays, the urban traffic is characterized by frequent occurrence of traffic jams in which cars move at low speeds. The sources of supply for electric vehicles are mainly electrochemical batteries. Reduction of the maximum value of supply current allows to extend the service life of batteries and improvement of the drive efficiency extends the vehicle range.

“…Switched reluctance machines need a comparatively large dc-link capacitor to smoothen the dc-link voltage due to the high amount of magnetization energy that oscillates between the dc-link and the machine [79]. A large dc-link capacitor increases the size, weight and price of the SRM inverter compared to inverters for conventional rotating field machines.…”

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.

A switched reluctance (SR) machine drive has many advantages over other competing drive technologies in terms of reliability and fault tolerance, which makes it particularly attractive for safety critical applications in more electric aircraft technologies. However, an SR machine drive requires a large DC-link capacitor to buffer the de-fluxing magnetic energy during a phase commutation period and to filter out ac harmonic currents from contaminating the DC supply. This paper describes a switching technique for minimisation of the DC-link capacitance in SR machine drives and presents experimental results from a laboratory demonstrator. The proposed switching method aims to maintain a constant average DC-link current over a switching cycle, thus eliminating commutation-induced low frequency current harmonics. Consequently, the DC-link capacitance can be minimised. The effectiveness of the proposed technique is assessed through filter design and demonstrated by experiments with a dSPACE control platform.
