Title
(EN) HIGH SPEED OPERATION OF AN ELECTRIC MACHINE
(FR) FONCTIONNEMENT À GRANDE VITESSE D'UNE MACHINE ÉLECTRIQUE
Abstract
(EN)
A hybrid electric vehicle having a controllable switch that enables a DC link to be operated independent from an energy storage system (ESS) is provided. The ESS is selectively couplable to the DC link via the controllable switch. A processor is configured to control the switch to open and close under certain conditions. When the switch is opened, the processor is configured to instruct an engine controller to cause an engine which is coupled to a generator to boost engine output. The generator is coupled to a generator inverter which is also coupled to the DC link. A motor inverter is also coupled to the DC link and is configured to provide AC power to the motor.
(FR)
L'invention concerne un véhicule électrique hybride, lequel véhicule a un commutateur pouvant être commandé qui permet à une liaison en courant continu de fonctionner indépendamment d'un système de stockage d'énergie (ESS). Le système de stockage d'énergie peut être couplé de manière sélective à la liaison en courant continu par l'intermédiaire du commutateur pouvant être commandé. Un processeur est configuré de façon à commander l'ouverture et la fermeture du commutateur dans certaines conditions. Quand le commutateur est ouvert, le processeur est configuré de façon à commander un dispositif de commande de moteur à combustion afin d'amener un moteur à combustion qui est couplé à un générateur à amplifier la sortie du moteur. Le générateur est couplé à un onduleur de générateur qui est également couplé à la liaison en courant continu. Un onduleur de moteur est également couplé à la liaison en courant continu, et est configuré de façon à délivrer une alimentation en courant alternatif au moteur.
