Abstract

Système d'alimentation en courant pour produire un signal indiquant l'état du courant fourni. Le système comporte des moyens 100 pour convertir une tension alternative en une tension continue d'un premier niveau, des moyens pour transformer la première tension continue en une tension continue de niveau bas, des moyens pour détecter la tension continue apparaissant à la sortie des moyens transformateurs, et des moyens 400 répondant à la tension continue de niveau bas pour engendrer un signal d'état d'un premier niveau avant la mise en marche du système, ayant un second niveau quand la tension continue atteint une première valeur prédeterminée et ayant à nouveau le premier niveau si la tension continue de niveau bas tombe en dessous d'une première tension prédéterminée. Application : commande d'interruption de priorité dans les ordinateurs en cas de panne de courant d'alimentation.Power supply system to produce a signal indicating the state of the current supplied. The system comprises means 100 for converting an alternating voltage into a direct voltage of a first level, means for transforming the first direct voltage into a direct voltage of low level, means for detecting the direct voltage appearing at the output of the means transformers, and means 400 responding to the low level DC voltage for generating a state signal of a first level before the system is turned on, having a second level when the DC voltage reaches a first predetermined value and having to again the first level if the low level DC voltage falls below a first predetermined voltage. Application: Priority interrupt control in computers in the event of a power failure.
