Abstract
(DE)
Die Erfindung betrifft ein Netzteil (7) für ein elektrisches Steuergerät aufweisend einen Transformator (1) mit einer mittels eines schaltbaren Primärschalters (8) ansteuerbaren Primärspule (2) und wenigstens einer Sekundärspule (3,4), wobei die Primärspule (2) und die wenigstens eine Sekundärspule (3,4) auf einem gemeinsamen Magnetkern angeordnet sind, wobei die wenigstens eine Sekundärspule wenigstens zwei Ausgänge mit steuerbaren Ausgangsspannungen bereitstellt, und wobei der wenigstens einen Sekundärspule (3,4) für jeden der wenigstens zwei Ausgänge ein schaltbarer Sekundärschalter (13,14) zugeordnet ist, wobei das Netzteil (7) eine Signalverarbeitungs- und Berechnungseinheit (9) umfasst, die dazu eingerichtet ist, den Primärschalter (8) und die Sekundärschalter (13,14) mittels Pulsgeneratoren (10,15,16) anzusteuern, wobei die wenigstens zwei Ausgänge sequenziell geschaltet sind, um wenigstens zwei steuerbare Ausgangsspannungen bereitzustellen.
(EN)
The invention relates to a power supply (7) for an electric control unit having a transformer (1) with a primary coil (2), which can be actuated by means of a switchable primary switch (8), and with at least one secondary coil (3, 4), the primary coil (2) and the at least one secondary coil (3, 4) being arranged on a common magnetic core, the at least one secondary coil providing at least two outputs with controllable output voltages, and the at least one secondary coil (3, 4) being assigned a switchable secondary switch (13, 14) for each of the at least two outputs. The power supply (7) comprises a signal-processing and calculating unit (9) which is designed to actuate the primary switch (8) and the secondary switches (13, 14) by means of pulse generators (10, 15, 16), wherein the at least two outputs are connected sequentially in order to provide at least two controllable output voltages.

L'invention concerne un bloc d'alimentation (7) pour un appareil de commande électrique comportant un transformateur (1) muni d'une bobine primaire (2) qui peut être actionnée au moyen d'un interrupteur primaire (8) commutable et au moins une bobine secondaire (3, 4), la bobine primaire (2) et l'au moins une bobine secondaire (3, 4) étant disposées sur un noyau magnétique commun. Au moins une bobine secondaire fournit au moins deux sorties avec des tensions de sortie contrôlables, et un interrupteur secondaire (13, 14) commutable pour chacune des au moins deux sorties étant associé à l'au moins une bobine secondaire (3, 4). Le bloc d'alimentation (7) comprend une unité de traitement et de calcul de signaux (9) agencée pour commander l'interrupteur primaire (8) et les interrupteurs secondaires (13, 14) au moyen de générateurs d'impulsions (10, 15, 16). Les au moins deux sorties sont connectées séquentiellement pour fournir au moins deux tensions de sortie contrôlables.
