In this paper, the Switched Reluctance Machine (SRM) is used as an AC generator. Power management requires circuit schemes based on well-known rectifiers which are shown and discussed. The aim of the circuits is to load a battery bank. As the operating conditions of the generator are associated with rotor speed, the topologies shown allow the generator to work in optimum conditions from the point...
We analyzed an AC self-excited switched reluctance generator used as a battery charger, using a second- order nonlinear oscillator model. Generator capacity can be maintained under variable rotor speed by adapting the external capacitance. The AC voltage generated is rectified and adapted with a DC-DC converter to battery voltage. To keep the flux machine under control, the rectified bus voltage should...
FE simulation data provides information about magnetic properties corresponding to a range of foreseen current excitation and rotor positions. This information needs further processing to derive other electric parameters, among which, inductance plays an important role for simulation and modeling purposes. This paper describes this process looking for analytical expressions and evaluating the incidence...
Switched Reluctance Machine (SRM) has a nonlinear behavior which difficults its understanding. The electric model shows this nonlinear behavior and it is difficult to derive conclusions but for the linear case. Simulators appear as the ideal tools for studying the machine. Although some papers report simulation models for this machine working in motoring and generating modes, the generating mode is...
The switched reluctance motor can be used in generation mode by selecting the firing angles of the phases. This implies the use of the asymmetrical half bridge Miller converter and position sensors or position estimators. In this paper an alternative current (AC) switched reluctance generator is studied. Generation is obtained by doing resonate each phase inductance with an external AC capacitor....
