Abstract

Abstract Translated from French Circuit de commande de puissance, destiné à fournir, en liaison directe, un courant d'intensité suffisante pour commander la base d'un transistor de puissance (21) dans un dispositif d'alimentation à découpage. Power control circuit intended to supply, in direct connection, a current of sufficient intensity to control the base of a power transistor (21) in a switching power supply device. L'invention prévoit d'acquérir différentes informations analogiques représentatives des états électriques et magnétiques du dispositif commandé, de les traiter, et de les regrouper dans un processeur central de surveillance (47), dont la sortie commande deux éléments de puissance (48, 49), l'un fournissant, l'autre absorbant le courant de base du transistor de puissance de commutation (21). The invention provides for acquiring various analog information representative of the electrical and magnetic states of the controlled device, for processing them, and for grouping them in a central monitoring processor (47), the output of which controls two power elements (48, 49 ), one providing, the other absorbing the base current of the switching power transistor (21). Application aux alimentations à découpage et aux dispositifs de balayage ligne en télévision. Application to switching power supplies and line scanning devices in television.
