Title (EN) SYSTEMS AND METHODS FOR BALANCING ELECTRICALLY-ISOLATED POWER SOURCES
(FR) SYSTÈMES ET PROCÉDÉS POUR ÉQUILIBRER DES SOURCES D'ALIMENTATION ÉLECTRIQUEMENT ISOLÉES
Abstract:
(EN) An electrical power system (163) for an aircraft (20) can have a plurality of power sources 166 to provide power to the components of the aircraft (20). The voltage levels of the power sources (166) can be balanced while maintaining electrical isolation between the power sources (166). A power system controller (506) can selectively control switches (508) to connect a single power source (166) to an energy storage device (510) to adjust the voltage level of the power source (166) to a desired voltage level by either charging or discharging the power source (166). The power source (166) can charge the energy storage device (510) to lower the voltage level of the power source (166) or the energy storage device (510) can be used to charge the power source (166) to raise the voltage level of the power source (166).
(FR) L'invention concerne un système d'alimentation électrique (163) pour un aéronef (20) qui peut avoir une pluralité de sources d'alimentation (166) afin de fournir de l'énergie aux composants de l'aéronef (20). Les niveaux de tension des sources d'alimentation (166) peuvent être équilibrés tout en maintenant une isolation électrique entre les sources d'alimentation (166). Une unité de commande de système d'alimentation (506) peut commander sélectivement des commutateurs (508) afin de connecter une seule source d'alimentation (166) à un dispositif de stockage d'énergie (510) afin de régler le niveau de tension de la source d'alimentation (166) à un niveau de tension souhaité en chargeant ou en déchargeant la source d'alimentation (166). La source d'alimentation (166) peut charger le dispositif de stockage d'énergie (510) afin d'abaisser le niveau de tension de la source d'alimentation (166), ou le dispositif de stockage d'énergie (510) peut être utilisé afin de charger la source d'alimentation (166) afin d'élever le niveau de tension de la source d'alimentation (166).
