Abstract

Système d'éclairage à courant continu capable de desservir tous les appareils électriques d'utilisation finale, de manière à conserver des conditions normales d'éclairage pour des appareils d'éclairage fonctionnant en courant continu et présentant également des charges compatibles avec le courant continu. Un dispositif de conversion et de commande de courant reçoit du courant alternatif depuis un service public ou une source analogue de courant alternatif, convertit le courant alternatif en courant continu et alimente des appareils d'éclairage ou tout autre appareil d'utilisation finale compatible avec le courant continu. On peut brancher sur l'appareil une ou plusieurs autres sources de courant continu et combiner ces dernières à l'intérieur de l'appareil avec la source convertie reliée à la charge. Une batterie rechargeable de réserve sert d'autre source de courant continu et peut maintenir le courant pendant les défaillances d'alimentation de la ligne en courant. On peut éventuellement brancher une autre source de courant continu, telle qu'une source de courant continu photovoltaïque, sur le dispositif de commande de courant, afin d'effectuer une alimentation en courant continu proportionnelle aux charges de courant continu. Dans un autre mode de réalisation, on peut brancher une variété de sources de courant sur ce dispositif de commande, telles qu'un générateur associé fonctionnant au gaz, afin d'effectuer une alimentation en courant continu. Ce système peut également fonctionner de façon autonome sans réseau d'alimentation en courant alternatif.
