Abstract

Procédé de régulation de l'intensité de moteurs triphasés alimentés par un convertisseur. On forme trois tensions calculées ou obtenues au moyen d'agencements de détection de valeur réelle, dont la fréquence, l'amplitude et le déphasage correspondent à la phase des tensions d'alimentation du moteur et qui sont ajoutées comme grandeur perturbatrice aux tensions qui proviennent de l'addition de la différence entre valeur réelle et valeur prescrite des trois intensités de moteur et d'une tension auxiliaire triangulaire. Applications : moteurs de traction.Method of regulating the intensity of three-phase motors supplied by a converter. Three voltages are formed, calculated or obtained by means of real value detection arrangements, the frequency, amplitude and phase shift of which correspond to the phase of the supply voltages of the motor and which are added as a disturbing quantity to the voltages which come from the addition of the difference between the actual value and the prescribed value of the three motor currents and of a triangular auxiliary voltage. Applications: traction motors.
