Abstract
(DE)
Die Anordnung weist mehrere Kippschwingung-Oszillatoren (31) auf, denen je eine Synchronisier-Einheit (32) und eine Pulsabgabe-Einheit (33) zugeordnet sind. Jeder Oszillator (31) besitzt zwei Ausgänge (35, 60), von denen der eine (60) einen Offener-Kollektor-Punkt (open collector point) darstellt. Die Synchronisier-Einheiten (32) weisen je zwei gegenpolig geschaltete Dioden (91, 92) auf sowie einen als Verstärker geschalteten Transistor (93). Der eine Ausgangspol ist jeweils mit einem Offener-Kollektor-Punkt (60) verbunden, der andere Augangspol (83) liegt entweder offen oder ist über eine Leitung (38) mit den entsprechenden Ausgangspolen (83) der anderen Synchronisier-Einheiten (32) verbunden. Liegt ein Ausgangspol (83) offen, so schwingt der zugeordnete Oszillator (31) frei. Ist der Ausgangspol (83) dagegen an die Leitung (38) angeschlossen, so schwingen die zugeordneten Oszillatoren (31) synchron. Die Anordnung dient zum Synchronisieren von Wandlern, die den Strom von Solarzellen mit stets maximalem Wirkungsgrad in eine Batterie pumpen.
(EN)
The device of the invention has several time-base oscillators (31), each associated with a synchronizing unit (32) and a pulse-emitter unit (33). Each oscillator (31) has two outputs (35, 60), one (60) of which is an open collector point. The synchronizing units (32) each have two diodes (91, 92) connected up with their poles in opposition, plus a transistor (93) connected up as an amplifier. One output pole in each case is connected to an open collector point (60), while the other output pole (83) is either open or connected via a line (38) to the corresponding output poles (83) of the other synchronizing units (32). If an output pole (83) is open, the associated oscillator (31) oscillates freely. If the output pole (83) is connected into the line (38), however, the associated oscillators (31) oscillate synchronously. The device is designed to be used to synchronize transducers which pump current from solar cells to a battery, maintaining the efficiency at the maximum level.
(FR)
Le dispositif présente plusieurs oscillateurs à oscillations de relaxation (31), auxquels sont associés, pour chacun d'eux, une unité de synchronisation (32) et une unité génératrice d'impulsions (33). Chaque oscillateur (31) possède deux sorties (35, 60), dont l'une (60) représente un point collecteur ouvert (''open collector point''). Les unités de synchronisation (32) présentent chacune deux diodes (91, 92) montées en polarité opposée, ainsi qu'un transistor (93) monté an amplificateur. L'un des pôles de sortie est raccordé à un point collecteur ouvert (60), cependant que l'autre pôle de sortie (83) est, ou bien ouvert, ou bien raccordé, par l'intermédiaire d'un conducteur (38), aux pôles de sortie correspondants (83) des autres unités de synchronisation (32). Lorsqu'un pôle de sortie (83) est ouvert, l'oscillateur qui lui est associé (31) oscille librement. Si, par contre, le pôle de sortie (83) est relié au conducteur (38), les oscillateurs associés (31) oscillent de façon synchronisée. Le dispositif sert à la synchronisation de convertisseurs puisant le courant provenant de cellules solaires pour l'acheminer dans un accumulateur, avec un rendement maximal constant.
