“…11 and 12 is the commutator that is responsible for selecting the turn-on and turn-off (or conduction) angles. While this is challenging for the SRM as well, the optimization is more straightforward because only the turn-on angle dictates the peak phase current; see [12] for a discussion of excitation optimization for the SRM. For the SRG, both turn-on and turn-off angles contribute to peak phase current above base speed.…”

This paper discusses how the switched reluctance generator (SRG) converts energy as directed by a controller. Beginning with a review of the electromechanics of generation, the paper identifies the implications of the energy conversion process on how the SRG is controlled. The structure of the SRG controller for speed-control and power-control applications is discussed. Practical implementation details for commutation of the SRG are reviewed. Concepts are illustrated with a 6-kW SRG designed to serve as a starter/alternator in automotive applications.

A current-controlled switched reluctance motor drive for variable speed applications with efficiency optimization is presented. Firing angles are computed online, the turnon is calculated by means of the rule of Bose, and the turn-off is calculated using the general theory of the optimal turn-off angle proposed by Gribble. In steady state operation, the initial selection of firing angles is fine-tuned by means of an algorithm that minimizes the input power of the drive. An efficiency and electrical energy consumption comparison with a commercial vector-controlled induction motor drive of the same size is also included. Experimental results show that the proposed switched reluctance motor drive is a good choice for applications that require slow varying loads and energy savings.

Due to the reluctant effect that exists between the stator and the rotor and its conception, the torque of Switched Reluctance Motor (SRM) has a ripple waveform. Hence it is necessary to reduce these undulations, which are undesirable and harmful for a best fonctionnement of system. In order to minimize these undulations, we present in the follow paper the current hysteresis control of the SRM supplied with half-bridge asymmetrical inverter. This is realized with a right angles commutations choice of the power converter.
