Description

  

  Verfahren zur     Verbesserung    des Wirkungsgrades von Anlagen zur Erzeugung von       Hochfrequenzschwingungen.       Die Erfindung bezieht sich auf die Ver  besserung von Anlagen zur Erzeugung von       Hochfrequenzschwingungen.    Wird bei der       Frequenzvervielfachung        mittelst    Transforma  toren mit hochgesättigtem Eisenkern, durch  dessen hohe     Sättigung    die primär auf  gedrückte Wellenform so verzerrt wird, dass  in einem     angeschlossenen    Sekundärkreis jede  Vielfache der Grundfrequenz     herausfilterbar     ist, gleichgültig, ob dabei Gleichstrom  magnetisierung angewendet wird oder nicht,

    so ist auch an den Primärklemmen die  Spannung sekundärer Frequenz entsprechend  dem     Übersetzungsverhältnis    des Transforma  tors vorhanden und drückt durch .den Primär=  kreis einen dem     Widerstande    entsprechenden  Strom. Das ist eine der Ursachen des  schlechten Wirkungsgrades der     Frequenzver-          vielf        achungen.     



  Der neue Gedanke der Erfindung ist der,  in den primären Kreis derart grosse, eventuell  gleichzeitig zur     Abstimmung    benutzbare  Drosselspulen einzuschalten, dass der     Wech-          selstromwiderstand    des primären Kreises für  die Spannung höherer Frequenz einen     im       Verhältnis zum Verbrauchskreise mindestens  doppelten oder grösseren Widerstand be  deutet.    Um die Drosselspulen nicht zu gross zu  bekommen, ist es zweckmässig, den Generator  mit dem Transformator nur lose zu koppeln,  und zwar entweder durch einen stark streuen  den Transformator oder besser durch einen       Kopplungsvariometer.     



  Die Zeichnung zeigt ein Schaltungsschema  für das Verfahren gemäss der Erfindung als  Ausführungsbeispiel.  



  In der Zeichnung ist . ein Schwingungs  erzeuger; 2 und 4 sind     Abstimmkondensa-          toren;    8 ist das     Kopplungsvariometer;    5 ist  eine Sekundärfrequenzen abschirmende Selbst  induktion; 6 ist ein     Frequenztransformator,     mit hochgesättigtem Eisenkern, durch dessen  hohe Sättigung die Wellenform so verzerrt  wird, dass jede     beliebige    Vielfache der  Grundfrequenz herausgefiltert werden kann;  7 und 8 sind     Abstimmelemente    für die Se  kundärfrequenzen und 9 die in     beliebiger     Weise gekoppelte     Antenne.  



  Process for improving the efficiency of systems for generating high-frequency oscillations. The invention relates to the improvement of systems for generating high-frequency vibrations. If the frequency multiplication is carried out by means of transformers with a highly saturated iron core, the high saturation of which distorts the waveform that is primarily under pressure so that every multiple of the fundamental frequency can be filtered out in a connected secondary circuit, regardless of whether direct current magnetization is used or not,

    the voltage of the secondary frequency is also present at the primary terminals according to the transformation ratio of the transformer and pushes through the primary circuit a current corresponding to the resistance. This is one of the causes of the poor efficiency of the frequency multiplication.



  The new idea of the invention is to switch such large choke coils into the primary circuit, possibly simultaneously usable for tuning, that the AC resistance of the primary circuit for the voltage of higher frequency means at least double or greater resistance in relation to the consumption circuit. In order not to get the choke coils too big, it is advisable to couple the generator with the transformer only loosely, either by a widely scattering transformer or better by a coupling variometer.



  The drawing shows a circuit diagram for the method according to the invention as an exemplary embodiment.



  In the drawing is. a vibration generator; 2 and 4 are tuning capacitors; 8 is the coupling variometer; 5 is a secondary frequency shielding self-induction; 6 is a frequency transformer with a highly saturated iron core, the high saturation of which distorts the waveform in such a way that any multiple of the fundamental frequency can be filtered out; 7 and 8 are tuning elements for the secondary frequencies and 9 the antenna coupled in any way.
