Anordnung zur Verhinderung der Übertragung von Oberwellen ans dem Arbeitskreis eines Generators in einen zweiten lireis, z. B. den Verbraucherlu'eis.
Die vorliegende Erfindung betrifft eine Schaltungsmassnahme, um die Übertragung von Oberwellen aus dem Arbeitskreis eines Generators auf den Verbraucherkreis zu verhindern und soll näher an Hand der Schaltung erläutert werden.
In der Figur ist ein rückgekoppelter Röhrensender gezeichnet, an dessen Arbeitskreis eine Antenne angeschlossen ist. Die Kopplung der Antenne erfolgt nun gemäss der Erfindung über einen Transformator T, der drei Primärwicklungen enthält, von denen die eine 1 im induktiven Zweig des Arbeitskreises, die andere 2 im kapazitiven und die dritte 3 im Speisestromkreis liegt. Diese Primärwicklungen werden von den Strömen der Grundfrequenz und der Oberschwingungen durchflossen, u. zw. fliessen für die Grundfrequenz in den Wicklungen 1 und 2 annähernd gleiche Ströme. Für die Oberschwingungen jedoch ist der Widerstand des Induktivitätszweiges wesentlich grösser als der des Kapazitätszweiges. So z. B. verhalten sich daher die Ströme für die erste Oberschwingung im Kapazitätszweige und im Induktivitätszweige annähernd wie 1 : 4.
Nimmt man an, dass die Windungszahlen der Primärspulen 1 und 2 einander gleich sind und zusammen n-Windungen betragen, so ist die Zahl der Amperewindungen der Spulen 1 und 2 für die erste Oberschwingung vorausgesetzt, dass im Kapazitätszweig der Strom 4, im Induktivitätszweig

Arrangement to prevent the transmission of harmonics to the working group of a generator in a second lireis, z. B. the consumer ice cream.
The present invention relates to a circuit measure to prevent the transmission of harmonics from the working circuit of a generator to the consumer circuit and will be explained in more detail with reference to the circuit.
In the figure, a feedback tube transmitter is drawn, to whose working group an antenna is connected. According to the invention, the antenna is coupled via a transformer T, which contains three primary windings, one of which 1 is in the inductive branch of the working circuit, the other 2 in the capacitive and the third 3 in the supply circuit. These primary windings are traversed by the currents of the fundamental frequency and the harmonics, u. Between windings 1 and 2, approximately the same currents flow for the fundamental frequency. For the harmonics, however, the resistance of the inductance branch is significantly greater than that of the capacitance branch. So z. B. therefore the currents for the first harmonic in the capacitance branch and in the inductance branch behave approximately like 1: 4.
Assuming that the number of turns of the primary coils 1 and 2 are equal to each other and together amount to n turns, the number of ampere turns of the coils 1 and 2 for the first harmonic is assumed that the current 4 in the capacitance branch and the inductance branch
