Description

Es ist bereits vorgeschlagen, an dem Frequenzvervielfachungstransformator einen Hilfskreis anzuschalten, der hauptsächlich eine von der Nutzfrequenz abweichende Ober-Schwingung führt und dadurch eine zusätzliche Verzerrung der Kurvenform herbeiführt, die eine wesentliche Verbesserung der sekundären Leistung ergibt.It has already been proposed to use a frequency multiplication transformer To switch on the auxiliary circuit, the main one deviating from the usable frequency harmonic leads and thereby causes an additional distortion of the curve shape, which is a significant improvement in the secondary Performance results.

Der vorliegenden Erfindung liegt die Erkenntnis zugrunde, daß eine noch weitere Verbesserung des Wirkungsgrades eintritt, wenn ein angeschalteter Hilfskreis ungefähr auf die Grundschwingung· abgestimmt ist. Es ist dadurch möglich, eine gewisse Anzahl von Gegen-Amperewindungen der Grundfrequenz auf ' den Transformatorkern zu drücken, die dessen Verluste außerordentlich reduzieren. Außerdem ist damit der besondere Vorteil verbunden, daß die resultierende Spannung an den Transformatorklemmen bei gleicher Stromstärke vermindert wird.The present invention is based on the finding that a still further improvement of the efficiency occurs when a connected auxiliary circuit is approximately on the Fundamental oscillation · is tuned. It is thereby possible to have a certain number of counter-ampere-turns of the fundamental frequency on 'the transformer core to push that of its Greatly reduce losses. It also has the particular advantage of that the resulting voltage at the transformer terminals at the same amperage is decreased.

Die Verbesserung des Wirkungsgrades durch Anwendung der Erfindung tritt bei Frequenzvervielfachungstransformatoren ein, un-S5 abhängig davon, ob der Transformatorenkern mit Gleichstrom magnetisiert wird oder nicht.The improvement in efficiency through application of the invention occurs with frequency multiplying transformers one, un-S5 depending on whether the transformer core magnetized with direct current or not.

Es können auch mehrere Hilfskreise ange- \ schaltet werden, die verschiedene Frequenzen ; vorzugsweise führen, um die Kurvenform noch mehr in erwünschter Weise zu verzerren, doch ist davon mindestens ein Hilfskreis ungefähr auf die Grundfrequenz abzustimmen.It is also possible to connect several auxiliary circuits that \ have different frequencies; preferably lead in order to distort the curve shape even more in the desired manner, but at least one auxiliary circuit is to be adjusted approximately to the fundamental frequency.

In der Zeichnung ist das neue Verfahren durch ein Schaltungsschema erläutert. 1 ist ein Hochfrequenzgenerator oder irgendeine andere Kraftquelle, 2 und 3 sind primäre Abstimmittel, 4 ist ein Frequenzvervielfachungstransformator, 5 und 6 sind sekundäre Abstimmiittel, 7 ist eine Antennenkopplungsspule und 8 und 9 sind Abstimmittel des gemäß der Erfindung vorgesehenen, ungefähr auf die Grundfrequenz abzustimmendien Hilfskreises. Statt eines Hilfskreises können auch zwei oder mehr angeschaltet werden.In the drawing, the new method is explained by a circuit diagram. 1 is a high frequency generator or any other power source, 2 and 3 are primary tuning means, 4 is a frequency multiplier transformer, 5 and 6 are secondary tuning means, 7 is an antenna coupling coil and 8 and 9 are tuning means of the one provided according to the invention, approximately to the Base frequency to be coordinated with the auxiliary group. Instead of one auxiliary circle, two or more to be turned on.
