| description | A pulsed control of an Externally Excited Synchronous Machines (EESM), including a boost circuit and method for (1) harvesting the field energy stored in rotor winding when the EESM is transitioning to the off state following an on pulses, (2) storing the harvested field energy on a storage device, (3) optionally topping up the harvested field energy stored on the storage device, and (4) supplying the harvested and stored field energy as a boost voltage to the rotor, just as the EESM is transitioning on for the next pulse, the boost voltage aiding the rotor in quickly overcoming its start-up inductance, rapidly turning on the rotor, resulting in a much faster transition time from the off state to the on state at the start of the next pulse.
Commande pulsée d'une machine synchrone à excitation externe (EESM), comprenant un circuit d'amplification et un procédé pour (1) récolter l'énergie de champ stockée dans l'enroulement rotorique lorsque l'EESM passe à l'état arrêté à la suite d'impulsions, (2) stocker l'énergie de champ récoltée sur un dispositif de stockage, (3) recouvrir facultativement l'énergie de champ collectée stockée sur le dispositif de stockage, et (4) fournir l'énergie de champ collectée et stockée en tant que tension d'amplification au rotor, juste au fur et à mesure de la transition de l'EESM pour l'impulsion suivante, la tension d'amplification aidant le rotor à surmonter rapidement son inductance de démarrage, tournant rapidement sur le rotor, conduisant à un temps de transition beaucoup plus rapide entre l'état arrêté et l'état allumé au début de l'impulsion suivante. |
