Abstract

L'invention concerne un système (201) d'alimentation électrique comportant une pluralité d'unités (100A, 100B et ainsi de suite), dont chacune est dotée d'une section (1) de convertisseur qui effectue une conversion de puissance; une section d'entrée et une section de sortie de chacune des unités (100A, 100B et ainsi de suite) étant reliées en parallèle; les unités (100A, 100B et ainsi de suite) étant en communication entre elles; et l'unité (100A) étant spécifiée en tant que module maître qui commande l'activation et l'arrêt des autres unités (100B, etc.). L'unité (100A) fait en sorte que toutes les autres unités (100B, etc.) soient activées lorsqu'un courant de sortie (Io) dépasse une valeur seuil, ledit courant de sortie ayant été détecté au moyen d'un circuit (5) de détection de courant de sortie. Dans les cas où toutes les unités (100B, etc.) sont activées, une unité parmi toutes les autres unités (100B, etc.) est arrêtée en se basant sur le total des courants de sortie des unités (100A, 100B et ainsi de suite). Il en résulte un système d'alimentation électrique capable de limiter l'utilisation des modules dans un état de surintensité lorsqu'un courant de charge est augmenté rapidement.
