Many different topologies for single-phase switched reluctance motors have been published, giving an impression of large numbers of unconnected techniques. To provide insight into this area, an overview of converter topologies is presented. Each is classified and a family tree of converters is derived. Selected converters are analysed and compared.Converters for SRMs can be made simple in comparison to inverters feeding AC motors since torque in SRMs is produced by unidirectional currents [2]. Generally, the cost of an SRM is very competitive compared to the other motor types such as induction, permanent magnets and universal motors. The unique structure of the SRM, due to absence of rotor windings or permanent magnets, contributes to the simple construction technique.The single-phase SRM (SP-SRM) is the simplest machine of all, and is therefore particularly attractive in the application of domestic appliances where cost is the driving factor.There are also the disadvantages of a SP-SRM which are the higher acoustic noise level [3] and increased torque ripple [4]. However, these will not be a hindrance if the SP-SRM is to be used in an inherently noisy application such as a fan or food processor. Nevertheless, the SP-SRM does require an inverter of sorts and the cost of this could make them not competitive when compared to simple voltage magnitude control applied to universal or dc motors [5].

This paper proposes a new asymmetric neutral-point diode-clamped (NPC) multilevel converter for a four-phase switched reluctance motor drive. The inbuilt NPC clamping capacitors are used for both voltage level clamping and also as dc rail voltage-boosting capacitors to increase the output power of the motor, particularly for high-speed electric vehicle applications. The new converter allows regenerative energy to be recovered back to the dc supply for rapid machine braking, thus increasing overall drive efficiency. Analysis of the different modes of converter operation, along with design equations for sizing the voltage-boosting capacitors, are detailed. The effect of capacitance on boost voltage and increased motor base speed is presented. Simulation and experimental results confirm the effectiveness of the proposed converter.

“…Thus, many key affairs must be treated. The typical ones include (i) motor design [7]; (ii) power circuit design and switching control; (iii) proper rotor position sensing and commutation setting; (iv) dynamic modeling; (v) current control [8,9]; (vi) speed control [10]; (vii) commutation shift [11][12][13]; (viii) voltage boosting [14][15][16][17]; (ix) field weakening via commutation shifting [11][12][13]; and (x) torque ripple and vibration reductions. Under high speed and/or heavy load, commutation shift with equivalent field-weakening effects is the effective way to improve the SRM winding current waveforms and thus the torquegenerating capability.…”

Although switched-reluctance machine (SRM) possesses many structural advantages and application potential, it is rather difficult to successfully control with high performance being comparable to other machines. Many critical affairs must be properly treated to obtain the improved operating characteristics. This chapter presents the basic and key technologies of switched-reluctance machine in motor and generator operations. The contents in this chapter include: (1) structures and governing equations of SRM; (2) some commonly used SRM converters;(3) estimation of key parameters and performance evaluation of SRM drive; (4) commutation scheme, current control scheme, and speed control scheme of SRM drive; (5) some commonly used front-end converters and their operation controls for SRM drive; (6) reversible and regenerative braking operation controls for SRM drive; (7) some tuning issues for SRM drive; (8) operation control and some tuning issues of switched-reluctance generators; and (9) experimental application exploration for SRM systems: (a) wind generator and microgrid; (b) EV SRM drive.
