Title (EN) METHOD AND APPARATUS FOR PROVIDING A REMEDIAL STRATEGY FOR AN ELECTRICAL CIRCUIT
(FR) PROCÉDÉ ET DISPOSITIF POUR FOURNIR UNE STRATÉGIE DE REDRESSEMENT À UN CIRCUIT ÉLECTRIQUE
Abstract:
(EN) A method and electrical circuit for dynamic reconfiguration of a DC-to-AC inverter comprising first and second power rails where each the rails has a power source. The method comprises monitoring the first and second power rails for short-circuit failure; and upon failure of one of the power rails, disconnecting the failed power rail from its power source.
(FR) L'invention concerne un procédé et un circuit électrique destinés à une reconfiguration dynamique d'un onduleur continu vers alternatif comprenant des premier et second pôles d'alimentation où chacun des pôles comporte une source d'énergie. Le procédé comprend la surveillance des premier et second pôles d'alimentation pour une défaillance en court-circuit et, lors de la défaillance de l'un des pôles d'alimentation, la déconnexion du pôle d'alimentation en défaut de sa source d'énergie.
