Machine à reluctance variable en fonctionnement moteur/générateur : contribution à l'optimisation de la structure et de l'alimentation

Abstract : The model of the Switched Reluctance Machines (SRM) is established. It is based on the knowledge of an analytic function of the flux which is calculated using a finite element code. We propose an interpolation method called method of Krigeage to obtain a function of the flux twice derivable according to the phase current and to the position of the rotor. We use this model to calculate the performances, in motor and generator modes, of three machines: three phases (structure 6/4), four phases (structure 8/6) and five phases (structure 10/8) with fixed current of the continuous source and fixed extemal dimensions. We show that the performances of this machines decrease with the speed. To resolve this problem, we propose to feed (in motoring and generating modes) the SRM by several structures of converters which are equipped with different boost capacitor circuit.
