Title (EN) METHOD AND SYSTEMS FOR AN ENGINE STARTER/GENERATOR
(FR) PROCÉDÉ ET SYSTÈMES POUR UN DÉMARREUR/GÉNÉRATEUR DE MOTEUR
Abstract:
(EN) A method and system for an engine starter/generator is provided The starter/generator system includes a three phase squirrel cage induction machine, a three phase inverter/converter electrically coupled Io the three phase squirrel cage induction machine The starter/generator system also includes a bidirectional DC-DC converter electrically coupled to the three phase inverter/converter, and a digital control board configured to sensorlessly determine a rotor angle from a plurality of phase currents to the induction machine during a start mode. During the start mode, logic in the digital control board configures the starter: generator system into a combination of an induction motor, a three phase DC-AC inverter, and a DC -DC boost converter, and during a generate mode, the logic in the digital control board configures the starter generator system into a combination of an induction generator, a three phase AC-DC converter, and a DC-DC buck converter.
(FR) L'invention porte sur un procédé et sur des systèmes pour un démarreur/générateur de moteur. Le système démarreur/générateur comprend une machine d'induction triphasée à cage d'écureuil et un convertisseur/inverseur triphasé couplé électriquement à la machine triphasée d'induction à cage d'écureuil. Le système démarreur/générateur comprend également un convertisseur continu/continu bidirectionnel couplé électriquement au convertisseur/inverseur triphasé, et un tableau de commande numérique configuré de façon à déterminer sans capteur un angle de rotor à partir d'une pluralité de courants de phase vers la machine d'induction durant un mode de démarrage. Durant le mode de démarrage, la logique du tableau de commande numérique configure le démarreur : le système générateur en une combinaison d'un moteur d'induction, d'un inverseur continu-alternatif triphasé, d'un convertisseur élévateur de tension courant continu-courant continu et durant un mode de génération, la logique du tableau de commande numérique configure le système démarreur/générateur en une combinaison de générateur d'induction, d'un convertisseur continu-alternatif triphasé, et d'un convertisseur survolteur-dévolteur de tension continu-continu.
