“…As the generated voltage is normally fed to a DC link capacitor, once this capacitor is charged, it can provide excitation energy through a power controller, leading to full self-excitation operation. Recent studies have also shown the SRM working as autonomous generators [10][11][12]. Although switched reluctance generators have been primarily studied for automotive and aerospace systems [3,5], recent trends show the possibility of its use in other variable speed constant frequency (VSCF) applications, such as wind power systems [13][14].…”

This paper reports on the switched reluctance machine operating as motor/generator (SRM/G) excited through an external power source. The half-bridge static converter topology is used to drive the machine in either modes of operation. Transition from motor to generator mode is firstly discussed and results from both simulation and experimental tests are included. Operating as generator, the output generated voltage is a function of the phase magnetization level during excitation; therefore, by controlling the phase excitation level, the output voltage is also controlled. Three output voltage control techniques are proposed and analyzed: 1-Variable Angle (VA), effected by controlling the phases turning off angles with a fixed DC link excitation voltage; 2-Chopping (CH), attained by chopping the DC link supply during the phases magnetization while keeping a fixed conduction period; and 3-Variable Link (VL), reached by controlling the DC link excitation voltage by means of a DC-DC buck converter in a fixed conduction period. For the experimental work, full digital control is implemented. Results obtained with the implementation of the output voltage control techniques are presented. Relative performance comparison is included, showing that the CH followed by VL strategy brings the best outcome.

“…A single phase SR AC Generator has been simulated (simulink) and analyzed in steady state in [34].It is shown in their work that the machine returns mechanical energy to the prime mover twice per cycle and it can be both supplying and returning electrical energy at the same time. In [35], an Ac self-excited SRG used is analyzed using a second order nonlinear oscillator model which can be used as a battery charger in isolated locations. The modeling of a linear SRG is dealt in [36].…”

Wind power as one of a greatly developed distributed generation techniques is gaining increasing significance throughout the world. Switched Reluctance Motor when operated as Generator is proved to be a real alternative to conventional variable speed drives in many applications, especially in the extraction of maximum energy in wind energy generation system with the variable wind speeds. This paper reviews the technology status and recent trends of switched reluctance generator covering the various aspects of Modeling, Design, Simulation, Analysis and Control.

“…The SRG has various desirable features namely, simple and solid structure, easiness of maintenance, small moment of rotor inertia, support of both high-rotational speed and high-temperature operation, and low manufacturing cost because the SR generator has no rotor windings and no permanent magnet [2][3][4]. Advantages of using SRG have been proved for some applications like starter/generator for gas turbine [5][6][7], wind turbine generator [8][9][10][11], battery charger [12], fluxcompression electromechanical converter [13], and as an alternator for automotive applications [14][15][16]. The aerospace and automotive applications are generally characterized by high-speed operation.…”

Abstract-This paper introduces a new configuration for a two phase field assisted hybrid switched reluctance generator, which can operate in motoring mode as well. This concept allows higher output power production compare to standard SRG. The proposed novel generator consists of two magnetically independent stator and rotor sets (layers), where each stator set includes four salient poles with windings wrapped around them, while the rotor comprises of two salient poles with different arc lengths and no windings. There is a stationary reel, which has the field coils wrapped around it and is placed between the two-stator sets. In this format, the developed magnetic field from the stator poles travels to the rotor then to the rotor shaft and finally completes its path via the generator housing. To evaluate the generator performance, two types of analysis, namely the numerical technique and the experimental study have been utilized. The analysis is carried out for the machine in self exited generator mode as well as field assisted mode. In the numerical analysis, the finite element analysis is employed, whereas in the experimental study, a proto-type generator has been built and tested.
