Description

Schwungradkreis, bei dem ein 'auf eine unerwünschte Frequenz abgestimmtes Kurzschlußglied zwischen den zur Abnahme der Nutzhochfrequenz vorgesehenen Punkten geschaltet ist Bei Frequenzvervielfacheranordnungen treten im allgemeinen Falle im verzerrten Hochfrequenzstrom sämtliche höheren Harmonischen der Grundfrequenz auf. Soll z. B. verdoppelt werden, wird ein Kopplungskreis auf a f abgestimmt und dadurch für diese Frequenz zu einem hohen Widerstande, während er für die übrigen Harmonischen je nach Ausgestaltung der Schaltung einen mehr oder weniger kleinen Widerstand darstellt. Besonders störend sind die von den tieferen Harmonischen, in vorliegendem Falle also die von der Grundwelle erzeugten Spannungen, die zugleich mit der Spannung der gewünschten Harmonischen auftreten. Um in möglichst weitgehendem Maße die Grundfrequenz f zu unterdrücken, hat man die Anwendung von Kurzschlußgliedern für die Grundfrequenz f vorgeschlagen, die zweckmäßiger Weise derart angeordnet sind, daß sie an Punkten des Schwingungskreises angeschlossen werden, die für die Nutzfrequenz Äquipotentialpunkte sind. Es kann dann eine genaue Abgleichung auf die Störfrequenz f stattfinden, ohne daß die Kreisabstimmung für die Nutzfrequenz beeinflußt wird.Flywheel circuit in which a 'tuned to an undesired frequency Short-circuit link between the points provided for taking off the useful high frequency is switched With frequency multiplier arrangements generally occur all higher harmonics of the fundamental frequency in the distorted high-frequency current on. Should z. B. are doubled, a coupling circle is matched to a f and this leads to a high resistance for this frequency, while for the rest Harmonics are more or less small depending on the configuration of the circuit Represents resistance. Particularly disturbing are those from the lower harmonics, In the present case, the voltages generated by the fundamental wave, which are at the same time occur with the voltage of the desired harmonics. To as far as possible To suppress the fundamental frequency f, one has to use short-circuit elements Proposed for the fundamental frequency f, which is expediently arranged in this way are that they are connected to points of the oscillation circuit, which for the Usable frequency are equipotential points. There can then be an exact match up the interference frequency f take place without the circular tuning for the useful frequency being affected.

Vorliegender Erfindung gemäß wird ein Schwungradkreis derart ausgebildet, daß, während der Anschluß des abgestimmten Kurzschlußgliedes anÄquipotentialpunkten des Sperrkreises stattfindet, der Anschluß der Nutzfrequenz zwischen einem der Äquipotentialpunkte und dem Zusammenschlußpunkt ungleicher Impedanzen erfolgt. Hierdurch ist eine Anordnung gegeben, bei welcher als das eine Element des Resonanzkurzschlußgliedes eine an und für sich in der Schaltung bedingte Impedanz Verwendung findet, anderseits ist jedoch die Anordnung so ausgeführt, daß bei Abstimmung des Kurzschlußgliedes die Resonanz des Schwungradkreises nicht geändert wird.According to the present invention, a flywheel circle is formed in such a way that that, during the connection of the matched short-circuit member to equipotential points of the trap circuit takes place, the connection of the useful frequency between one of the equipotential points and the junction point of unequal impedances. This is an arrangement given, in which as the one element of the resonance short-circuit member to one and impedance is used for itself in the circuit, on the other hand is However, the arrangement is carried out so that when voting the short-circuit member Resonance of the flywheel circuit is not changed.

In der Abbildung sind die Spulen A und B mit der Serienkapazität von D und E auf die Frequenz z t abgestimmt. B und E sind daher für die Grundfrequenz i resultierend eine Kapazität, die mit Hilfe der zu ihr parallel liegenden Spule C zu einer derartigen Induktiiztät gemacht werden können, daß sie zusammen mit der Kapazität D ein Kurzsählußglied für die Frequenz/ ergeben.In the picture are the coils A and B with the series capacity of D and E tuned to the frequency z t. B and E are therefore for the fundamental frequency i resulting in a capacitance, which with the help of the coil lying parallel to it C can be made such an inductance that it can be combined with the Capacity D a Kurzsählußglied for the frequency / result.
