Abstract

Une tension d'entrée Ue alimente, par un transistor 23 l'appareil d'utilisation 1 et par une diode 9 et une résistance de polarisation 10, un élément Ni-Cd, tandis qu'un condensateur tampon 18 est chargé par l'élément Ni-Cd 5 pendant les pauses entre impulsions. L'élément Ni-Cd 5 stabilise la tension d'alimentation à la connexion 7 d'un circuit de commutation 8. Lors d'un court-circuit de l'élément Ni-Cd 5, la tension d'alimentation du circuit de commutation 8 est recueillie aux bornes d'un diviseur de tension constitué par une résistance 21 et par une diode 19 tandis que, lors d'une coupure dudit élément, intervient une diode de stabilisation 20 montée en série avec la diode 19. Application particulière aux interrupteurs horaires.
