Title: (DE) STABILISIERTE GABELSTROMVERSORGUNG
(EN) REGULATED BIFURCATED POWER SUPPLY
(FR) ALIMENTATION EN PUISSANCE REGULEE A BIFURCATION
Abstract: front page image
(EN) The regulated power supply employs two separate sources of power (28, 30) which are serially connected by a variable impedance element, such as a transistor (32), connected between the two power sources. Output voltage of the power supply is equal to the sum of the individual power supply voltages minus a voltage drop across the variable impedance element. A sensor circuit (38) employing standby and active mode branches (40, 42) is coupled between output terminals of the power supply for control of the variable impedance element. The active branch of the sensor is switchably connected to an output power terminal (22) of the supply so as to be operative only during the active mode. The standby branch comprises a resistive network (52) coupled to a reference diode (44) while the active branch comprises a feedback amplifier (58) coupled to the reference diode.
(FR) L'alimentation en puissance régulée utilise deux sources de puissance séparées (28, 30) connectées en série par un élément d'impédance variable, par exemple un transistor (32) connecté entre les deux sources de puissance. La tension de sortie de l'alimentation en puissance est égale à la somme des tensions d'alimentation en puissance individuelles moins une chute de tension dans l'élément d'impédance variable. Un circuit détecteur (38) utilisant des branchements actif et auxiliaire (40, 42) est accouplé entre les bornes de sortie de l'alimentation en puissance pour commander l'élément d'impédance variable. Le branchement actif du détecteur est connecté de manière commutable à une borne de puissance de sortie (22) de l'alimentation pour fonctionner uniquement en mode actif. Le branchement auxiliaire comprend un réseau résistif (52) accouplé à une diode de référence (44) tandis que le branchement actif comprend un amplificateur de retour (58) accouplé à la diode de référence.
