Abstract
La présente invention concerne un dispositif de limitation de surintensité dans un appareil électrique en courant continu dans lequel se trouvent inclus des circuits de redressement et/ou de filtrage. Le dispositif est connecté entre la source d'énergie alimentant l'appareil et les circuits de redressement et/ou de filtrage Il est caractérisé en ce qu'il comprend un circuit de commutation présentant des entrées de commande liées à des moyens de temporisation associés à des moyens de détection de seuil de tension du secteur alternatif. Ces moyens sont associés de manière à commander le circuit de commutation pour limiter toute surintensité dans l'appareil électrique, au moment où le secteur est établi. Application au rétablissement progressif du courant dans une alimentation électrique continue.
