    摘要: A switching regulator comprises a single transformer (10) having a primary winding (10a) connected in an input circuit (11) for receiving direct-current energy and a secondary winding (10b) connected in an output circuit (12), and a switching transistor (21) connected in series with the primary winding (10a). A high frequency pulse generator (22) triggers the switching transistor so that it interrupts the direct-current energy at a high frequency. A rectifier (43) is provided for converting high frequency energy developed in the secondary winding into direct-current output energy, which is maintained constant by controlling the high frequency pulse generator. A low voltage detector (24) produces a signal when the direct-current energy in the input circuit falls below a specified value. In response to the signal from the low voltage detector, constant direct-current energy is derived from a battery (40) and applied to the output circuit as backup power.

    摘要: L'alimentation stabilisée comporte un transformateur secteur (5) suivi par un redresseur monophasé ou polyphasé (6) et par un intégrateur. La sortie positive du pont est connectée à l'entrée négative d'un régulateur de tension différentielle (8). La sortie positive du régulateur est connectée directement à la charge (13). La sortie négative du pont est connectée à la masse. La tension différentielle est asservie par une boucle de contre-réaction qui neutralise les variations amont et aval ainsi que les ondulations résiduelles. Cette tension différentielle (Udiff) est obtenue par une source indépendante à découpage à très haut rendement (UI). Elle fournit un apport de puissance supplémentaire qui s'ajoute à la puissance de sortie du transformateur.

    摘要: A power supply apparatus comprises power supplies (12, 14) that share the power requirements of a common lead (20) approximately equally. Either of the power supplies (12, 14) can act as the «master» while the other power supply acts as the «slave». The arrangement utilises an integrating differential error amplifier (54), an inverting amplifier (56), and a noninverting amplifier (58) which are electrically connected between the common load (20) and the power supplies (12, 14) to detect any difference in the output current of the power supplies (12, 14) due to a difference in output voltage, and to correct the difference by increasing the output voltage of the power supply having the lower output voltage until the difference is eliminated. In this manner, either power supply (12, 14) can act as the «master» while the other power supply acts as the «slave».

    摘要: A power supply comprises at least two supply circuits the output terminals of which are connected in series to supply a voltage across a load (V L ). Each circuit comprises a D.C. voltage source (Vm) in series with a switching valve (S), the maximum voltage across which is limited by diodes (D,) connected across the output terminals of the respective supply terminals, and a protection circuit (4). The protection circuit responds to the current flowing through the load, and on the occurrence of a first current threshold switches off the valve (S), and in the event of a higher current threshold fires a crowbar link (1) which shunts the source (Vm).
