The invention concerns a system to supply electrical power to at least one piece of electronic equipment (341, 342, 343), of a type comprising a main supply (31, 32) of alternating electrical power for normal use, one power storage unit (37) used as a secondary supply of direct current for back-up use, and means of detecting any failure in the said main supply source, controlling the transition (36) to back-up mode. With this invention, each of the said pieces of electronic equipment (341, 342, 343, 39) has its own energy converter (351, 352, 353, 311) delivering the internal supply of electricity needed by the said equipment, and supplied either directly by the said main supply source (31, 32) in normal use or directly by the said secondary power source (37) in the back-up mode.
L'invention concerne un système d'alimentation en énergie électrique d'au moins un équipement électronique (341, 342, 343), du type comprenant une source d'alimentation principale (31, 32) en énergie électrique alternative, utilisée en régime normal, une unité de stockage d'énergie (37), utilisée comme source d'alimentation secondaire en énergie électrique continue, en régime de secours, et des moyens de détection d'une défaillance de ladite source d'alimentation principale, commandant le passage (36) en régime de secours. Selon l'invention, on associe à chacun desdits équipements électroniques (341, 342, 343, 39) un convertisseur d'énergie distinct (351, 352, 353,311), délivrant l'alimentation électrique interne nécessaire audit équipement, et alimenté. - directement par ladite source d'alimentation principale (31,32), en régime normal; - directement par ladite source d'alimentation secondaire (37), en régime de secours.
