Description
Elektronenröhren Eine der Hauptschwierigkeiten bei der Erzeugung kurzer Wellen besteht bekanntlich darin, eine genügend große Energieausbeute zu erzielen. Durch eine -einfache Parallelschaltung mehrerer Röhren, die bei der Erzeugung langer Wellen ,allgemein üblich ist, kann nur in :den seltensten Fällen eine genugend große Leistung erzielt werden und man ist gezwungen, zu allen. möglichen Kunstgriffen zu greifen, die den Wirkungsgrad etwas verbessern. Auch .die bekannte Gegentaktschaltung, auf ,die sich die vorliegende Erfindung bezieht, bringt in der üblichen Anordnung nicht den gewünschten Erfolg.Electron tubes One of the main difficulties in producing short As is well known, waves consist in achieving a sufficiently large energy yield. By simply connecting several tubes in parallel, which in the generation of long Waves, which is common, can only be found in: the rarest of cases, a sufficiently large one Achievement is achieved and one is forced to go to all. possible tricks to grab, which improve the efficiency somewhat. Also. The well-known push-pull circuit, to which the present invention relates brings in the usual arrangement not the desired success.
Gemäß der Erfindung kann jedoch die Leistung mehrerer im Gegentakt arbeitender Elektronenröhren wesentlich gesteigert werden, indem -die Heizfäden über einen abstimmbaren, aus Selbstinduktion und Kapazität bestehenden Schwingungskreis hintereinandergeschaltet werden. Bei einem Versuchssender konnte durch die Maßnahme die Leistung auf das Fünffache derjenigen gesteigert wenden, die ohne Anwendung des abstimm,baren Kreises zu erzielen war.According to the invention, however, the performance of several in push-pull working electron tubes can be significantly increased by -the heating filaments via a tunable oscillation circuit consisting of self-induction and capacitance can be connected in series. In the case of a test transmitter, the measure the performance increased to five times that of those who apply without application of the voting circle was to be achieved.
Der Erfindungsgegenstand läßt sich am einfachsten an Hand der beispielsweisen Abbildung erläutern. Zwei Röhren R, und R. sind Bitter- und anodenseitig miteinander verbunden. Zwischen der Anodenverbindung A und Gitterverbindung G liegt eine Kapazität C zwecks Abstimmung des Gitteranodenkreises, der durch die innere Röhrenkapazität in bekannter Weise vervollständigt wird. Bei der in -der Abb. i dargestellten Schaltung sind zwei getrennte Heizbatterien H, und H~ vorhanden. Die Fäden beider Röhren sind .durch die Verbindungsleitungen V,, und V. hintereinandergeschaltet. Die beiden Batterien Hl und H@ liegen also parallel zueinander. Es sind jedoch bei dieser Schaltung zwei Batterien notwendig, um das Symmetrieverhältnis der genannten Anordnung nicht zu stören. In die Leitung h2 ist gemäß der Erfindung der aus Kapazität C,. und Induktivität L, bestehende abstimmbare Kreis eingeschaltet.The subject matter of the invention can be most easily illustrated using the examples Explain the illustration. Two tubes R, and R. are bitter and anode side with each other tied together. There is a capacitance between the anode connection A and the grid connection G. C for the purpose of tuning the grid anode circle created by the inner tube capacitance is completed in a known manner. In the circuit shown in Fig. I there are two separate heating batteries H, and H ~. The threads of both tubes are .Connected in series through the connecting lines V ,, and V. The two Batteries Hl and H @ are therefore parallel to one another. However, there are in this circuit two batteries are necessary to avoid the symmetry of the arrangement mentioned disturb. In line h2, according to the invention, the capacitance C i. and inductance L, existing tunable circuit switched on.
Die in Abb. : angegebene Schaltung unterscheidet sich von der der Abb. i dadurch, daß nur eine Heizbatterie H vorhanden. ist, die symmetrisch in die Anordnung eingeschaltet ist, indem sie zwischen die Leitung V, und eine Anzapfung der Induktivität L, gelegt ist.The circuit shown in Fig.: Differs from that of the Fig. I in that only one heating battery H is available. is that symmetrically into the Arrangement is switched on by placing it between line V, and a tap the inductance L, is placed.
Auch bei der in Abb. 3 gezeigten Anordnung ist das' Symmetrieverhältnis gewahrt, indem zwei abstimmbare Kreise vorgesehen sind, von welchen jeder zwischen der Heizbatterie H und einer Röhre liegt. Die Induktivitäten sind mit L_ und L? bezeichnet, während die Kapazitäten die Bezugszeichen CZ, C3 haben.Also in the arrangement shown in Fig. 3, the 'symmetry relationship by providing two tunable circuits, each of which is between the heating battery H and a tube. The inductances are with L_ and L? denotes, while the capacitors have the reference characters CZ, C3.
Es ist selbstverständlich, daß die erfindungsgemäße Anordnung in gleicher Weise arbeiten kann, wenn mehrere im Gegentakt arbeitende Gruppen von Elektronenröhren parallel geschaltet sind, also z. B. 3 X 2 Röhren parallel arbeiten.It goes without saying that the arrangement according to the invention in the same Way can work when several groups of electron tubes working in push-pull are connected in parallel, so z. B. 3 X 2 tubes work in parallel.
