Description

Schaltungsanordnung zur Stromversorgung von Funkgeräten,: insbesondere von tragbaren Geräten, aus zwei Niedervoltbatterien Zur Stromversorgung von tragbaren Funkgeräten ist es bekannt, den Röhrenheizstrom einer Niedervöltbatterie zu entnehmen und die Anodenspannung aus der gleichen Batterie durch einen Stranizerhacker und nachfolgender Transformation zu erzeugen. Bei der pulsierenden Stromentnahme durch den Zechacker entsteht hierbei jedoch an den Klemmen der Batterie durch den inneren Batteriewiderstand eine Wechselspannung, die sich dem Röhrenheizstrom überlagert. Zur Beseitigung dieses Störeinflusses, sind Diro:ssel und Kondensator notwendig, von denen der meist als Elektrolytkondensator ausgebildete Glättungskondensator wegen seines nicht unbeträchtlichen Raumbedarfs unerwünscht ist.Circuit arrangement for the power supply of radio devices: in particular from portable devices, from two low-voltage batteries For powering portable devices It is known to radio devices to take the tube heating current from a low-voltage battery and the anode voltage from the same battery through a stranizer chopper and subsequent transformation to generate. With the pulsating current draw through however, the chopper is created at the terminals of the battery by the internal one Battery resistance an alternating voltage that is superimposed on the tube heating current. To eliminate this interference, Diro: ssel and capacitor are necessary, of which the smoothing capacitor, which is usually designed as an electrolytic capacitor is undesirable because of its not inconsiderable space requirements.

Zur Vermeidung der Glättun,gseinrichtungen ist man deshalb dazu übergegangen, für die Röhrenheizung und die Anodenstromversorgung getrennte Niedervoltbatterien zu verwenden, die voneinander unabhängig sind, so daß der durch den Zechacker entstehende Wechselstrom die Röhrenheizung nicht beeinflussen kann.In order to avoid the smoothing devices, one has therefore switched to separate low-voltage batteries for the tube heating and the anode power supply to use, which are independent of each other, so that the resulting from the Zechacker AC current cannot influence the tube heating.

Die letztgenannte Anordnung besitzt jedoch den Nachteil, daß wegen .der in der Regel ungleichen Belastung des Heizkreises und des Anodenkreises die Batterien nicht gleichmäßig entladen werden, so daß ihr Ersatz bzw. ihre Aufladung nicht zum gleichen Zeitpunkt erfolgen kann.The latter arrangement, however, has the disadvantage that because of . the usually unequal load of the heating circuit and the anode circuit Batteries do not discharge evenly, so replacing them or recharging them cannot take place at the same time.

Zur Vermeidung dieses Nachteils wird bei einer Schaltungsanordnung mit zwei Niedervoltbatterien, von denen die eine den Heizstrom und die andere unter Zwischenschaltung eines Zechackers den Anodenstrom liefert, gemäß der Erfindung vorgeschlagen, die beiden Batterien über eine Niederfrequenzdrossel parallel zu schalten.To avoid this disadvantage, in a circuit arrangement with two low-voltage batteries, one of which is the heating current and the other under Interposition of a chopper supplies the anode current, according to the invention proposed to use a low frequency choke to connect the two batteries in parallel switch.

Die neue Schaltung ergibt sich prinzipm,äßig aus der Abbildung.The new circuit results in principle from the illustration.

Die beiden Niedervoltbatterien (z. B. 2-Volt-Sammler) i und 2 sind über die Drossel 3 parallel: geschaltet. Der Röhrenheizkreis wird an den Klemmen q. und 5 angeschlossen, und der Stromzerhacker 6 mit Transformator liegt an den Klemmen der Batterie 2. Die Anodenspannung wird den Klemmen 7 und 8 entnommen. Die neue Schaltung ermöglicht eine gleichmäßige Entladung der beiden Batterien und erspart den Glättungskondensator. Eine Beeinflussung der Röhrenheizung durch den Stromzerhacker findet nicht statt, da die durch die pulsierende Stromentnahme entstehende Wechselspannung durch die Drossel 3 und den als große Kapazität wirkenden Sammler i unterdrückt wird.The two low-voltage batteries (e.g. 2-volt collector) i and 2 are parallel via throttle 3: switched. The tube heating circuit is connected to the terminals q. and 5 connected, and the current chopper 6 with transformer is connected to the Terminals of battery 2. The anode voltage is taken from terminals 7 and 8. the new circuit enables an even discharge of the two batteries and saves the smoothing capacitor. An influence on the tube heating by the current chopper does not take place because the alternating voltage generated by the pulsating current draw suppressed by the throttle 3 and the collector i acting as a large capacity will.
