Description

Die Erfindung beschäftigt sich mit dem Problem, einen Allstromfernsehempfänger zu schaffen. Bei Allstromempfängern liegt bekanntlich das Netz direkt 'an den Schaltelementen des Empfangsgerätes. Ein Eingangstranisformator kann nicht verwendet werden, da der Empfänger ohne Umschaltung für Gleichstrom und Wechselstrom verwendbar sein soll. Bei Verwendung von Gleichstrom ist eine einen Transformator enthaltende Eingangsschaltung aber nicht verwendbar, bei Wechselstrom muß die Speisespannung erst gleichgerichtet und über eine Siebkette geglättet werden:. Zur Vereinfachung wird bei solchen Allstromempfängern der bekanntlich auch bei Gleichstromspeisung vorhandene Gleichrichter in der wirksamen Schaltung belassen, und es ist dann gleichgültig, ob das Netz Gleich- oder Wechselstrom führt.The invention deals with the problem of an all-current television receiver to accomplish. In the case of universal current receivers, as is well known, the network is directly connected to the switching elements of the receiving device. An input transformer cannot be used because the receiver can be used for direct current and alternating current without switching target. When using direct current is an input circuit including a transformer but not usable, with alternating current the supply voltage must first be rectified and smoothed over a sieve chain :. To simplify matters, such universal current receivers the rectifier, which is also known to be present in the case of direct current feed, in the effective one Leave the circuit as it is, and it does not matter whether the mains is direct or alternating current leads.

Es ist bekannt, zur Erzeugung einer hohen Gleichspannung einen besonderen Wechselstromgenerator höherer Frequenz zu verwenden, der mit 22o Volt betrieben wird und dessen Ausgangsspannung nach Transformation und Gleichrichtung als Anodenspannung für die Braunsche Röhre dient. Dieser besondere Generator bedingt einen verhältnismäßig großen zusätzlichen Aufwand. Es ist ferner bekannt, den Zeilenkip:pgenerator zurr Erzeugung der Hochspannung für die Kathodenstrahlröhre heranzuziehen.It is known to use a special one for generating a high DC voltage Use a higher frequency alternator operating at 22o volts and its output voltage after transformation and rectification as anode voltage for the Braun tube. This particular generator requires a relative great additional effort. It is also known to use the Zeilenkip: pgenerator zurr Use the generation of high voltage for the cathode ray tube.

Diese Schaltungen haben jedoch Nachteile: Die maximal vorhandene Betriebsspannung aus dem Netz beträgt 22o Volt, infolge des Spannungsabfalls im Gleichrichter beträgt die zum Betrieb übrigbleibende Gleichspannung dann nur noch etwa rgo Volt. Zum Betrieb eines Kippgenerators ist diese Spannung jedoch zu niedrig, besonders wenn man aus der Kippfrequenz auch noch die Anodenspannung für die Braunsche Röhre erzeugen soll, wie dies z. B. beim Einheitsfernseh:empfänger der Fall ist.However, these circuits have disadvantages: The maximum available operating voltage from the mains is 220 volts, due to the voltage drop in the rectifier the DC voltage remaining for operation is then only about rgo volts. To operation A relaxation generator, however, this voltage is too low, especially when one is out the sweep frequency should also generate the anode voltage for the Braun tube, how this z. B. with standard television: receiver is the case.

Die Erfindung gibt zur Vermeidung dieser Schwierigkeiten einen Weg an, die Anodenspannung der Kippröhre zu erhöhen:. Zu j diesem Zweck wird denn Anoden- bzw. Schirmgitterkreis der Röhre des Zeilenkippgenerators eine Wechselspannung, beispielsweise über einen Transformator, entnommen, diese gleichgerichtet und in Reihe mit der Netzspannung zur Erhöhung der Anodenspannung des Zeilenkippgenerators benutzt. Man wählt den Zeilenkippgenerator, weil er die höhere Frequenz bat und so kleinere Siebmittel benötigt werden.The invention provides a way of avoiding these difficulties to increase the anode voltage of the tilt tube: For this purpose the anode or screen grid circuit of the tube of the line-tilt generator an alternating voltage, for example via a transformer, this is rectified and in Series with the mains voltage to increase the anode voltage of the flyback generator used. The line toggle generator is chosen because it has the higher frequency and so smaller sieve media are needed.

Zur näheren Erklärung der Erfindung ist ein Ausführungsbeispiel in der Abbildung dargestellt: L'1 ist die Röhre des nur schematisch dargestellten Zeilenkippgenerators, beispielsweise eine Schirmgitterröhre. Die Netzspannung von 220 Volt wird über den Gleichrichter Z' z und eine Siebkette als Schirmgitterspannung an diese Röhre gelegt. Im Schirmgitterkreis liegen die Zeilenablenkspulen ZA. Mit diesen Zeilenablenkspulen sind die Spulen S gekoppelt und bilden mit ihnen einen Transformator. Die, so von der sägezahnförmigen Ablenkspannung in dien Spulen S induzierte Spannung wird im Gleichriehiter I'3 gleichgerichtet und in Reihe mit der Netzspannung der Anode des Kippzugeführt. Die _Xnodenspannung dieses, Kippgenerators V1 i,st somit um den vom Gleichrichter l'., gelieferten Betrag höher als die zur Verfügung stehende Netzspannung.For a more detailed explanation of the invention, an embodiment is shown in shown in the figure: L'1 is the tube of the line-tilt generator, which is only shown schematically, for example a screen grid tube. The mains voltage of 220 volts is supplied via the Rectifier Z 'z and a sieve chain as a screen grid voltage placed on this tube. The line deflection coils ZA are located in the screen grid circle. With these line deflection coils the coils S are coupled and form a transformer with them. The, so from the sawtooth-shaped deflection voltage induced in the coils S is im Gleichriehiter I'3 rectified and in series with the mains voltage of the anode of the Tilt-fed. The _Xnode voltage of this, relaxation generator V1 i, is thus around the from Rectifier l '., Supplied amount higher than the available mains voltage.
