Title
(EN) SYSTEM AND METHOD FOR GENERATOR PHASE SIGNAL MONITORING AND CONTROL
(FR) SYSTÈME ET PROCÉDÉ POUR LA SURVEILLANCE D'UN SIGNAL DE PHASE DE GÉNÉRATEUR ET COMMANDE
Abstract
(EN)
A vehicle electrical system comprises a generator and a control device coupled with the generator and operable to protect the generator from catastrophic failure while providing the electrical load in the electrical system with sufficient electrical power. The control device determines a loss of symmetry between two alternating phase signals generated by a first and second phase windings of a single or multiple stator generator. In particular, the control device determines a first and second average values of two of the two or more alternating phase signals and either limits or ceases the total electrical output current of the generator, via a generator output power controller, when the first average value differs from the second average value by a predetermined value. The control device may alternatively be configured to generate an error signal without varying the generator's total electrical output current even in the event of a malfunction.

La présente invention concerne un système électrique de véhicule qui comprend un générateur et un dispositif de commande couplé au générateur et pouvant fonctionner pour protéger le générateur d'une défaillance catastrophique tout en fournissant suffisamment de puissance électrique à la charge électrique du système électrique. Le dispositif de commande détermine une perte de symétrie entre deux signaux de phase alternée générés par des premier et second enroulements de phase d'un générateur à stator unique ou multiple. En particulier, le dispositif de commande détermine des première et seconde valeurs moyennes de deux des deux signaux de phase alternée ou plus et soit limite, soit interrompt le courant de sortie électrique total du générateur, par le biais d'un dispositif de commande de puissance de sortie de générateur, lorsque la première valeur moyenne est différente de la seconde valeur moyenne à hauteur d'une valeur préétablie. Le dispositif de commande peut en variante être conçu pour générer un signal d'erreur sans faire varier le courant de sortie électrique total du générateur, même en cas de mauvais fonctionnement.
