Abstract

L'alimentation en puissance à mode commuté de cette invention comprend un indicateur (12) de sous-tension de la tension d'entrée, un bloc (16) de surveillance de la tension de sortie, un circuit (23) exécutant une fonction logique et un commutateur commandé (24). Le circuit exécutant une fonction logique fonctionne de telle sorte qu'il commande le commutateur commandé (24) pour qu'il se ferme immédiatement lorsque le circuit surveillant la première tension de sortie a détecté que cette tension a atteint sa valeur nominale et que les informations relatives à la tension d'entrée indiquent qu'il existe une tension suffisante dans le circuit primaire de l'alimentation en puissance à mode commuté. La charge fournie par l'alimentation en puissance à mode commuté est ainsi fournie de manière régulée avec une première tension (V1) et ensuite seulement avec une deuxième tension (V2). Si la tension d'entrée est interrompue ou qu'elle devient trop faible le circuit exécutant une fonction logique commande alors au commutateur (24) de s'ouvrir immédiatement et la première tension (V1) est éliminée de la charge. D'autre part l'énergie accumulée dans les condensateurs du circuit secondaire de l'alimentation en puissance à mode commuté maintient la deuxième tension (V2) à sa valeur nominale pendant un moment. De cette manière la première tension (V1) est tout d'abord éliminée de la charge de manière régulée et la deuxième tension qui chute en fonction d'une constante temporelle reste efficace pendant un moment.
