Abstract

Système de commutation redondant insensible aux défaillances conçu pour un dispositif critique et comprenant une première paire de bornes se branchant sur une source de courant, un premier réseau comportant un premier fusible, un premier commutateur et un troisième commutateur branchés en série entre la première paire de bornes, un deuxième réseau parallèle au premier réseau comportant un deuxième fusible, un deuxième commutateur et un quatrième commutateur branchés en série entre la première paire de bornes, ainsi qu'une deuxième paire de bornes dont l'une est placée entre le premier et le troisième commutateurs et l'autre entre le deuxième et le quatrième commutateurs afin d'être raccordées au dispositif critique, de manière à en extraire le courant redondant quand le premier et le deuxième commutateurs sont ouverts et le troisième et le quatrième commutateurs fermés. Lorsque le premier, le deuxième, le troisième et le quatrième commutateurs sont ouverts, le fonctionnement insensible aux défaillances s'effectue à travers le premier fusible, le premier commutateur et le quatrième commutateur ou le deuxième fusible, le deuxième commutateur et le troisième commutateur.
