Gegenstand der Erfindung ist eine Schaltungsanordnung Zur Erzeugung von kontinuierlichem Gleichstrom aus Wechselstrom mittels. Gleichrichter zwecks Verwendung desselben als Speisestrom für Röhrengeneratoren in der drahtlosen Telegraphie. Hier ist die Erzeugung eines reinen Gleichstromes und die Unterdrückung aller Pulsationen von besonderer Bedeutung, weil bekanntlich nur dann,The invention relates to a circuit arrangement for generating continuous Direct current from alternating current by means of. Rectifier for the purpose of using the same as supply current for tube generators in wireless telegraphy. Here is the Generation of a pure direct current and the suppression of all pulsations of particular interest Meaning because, as is well known, only then
ίο wenn die durch den Röhrengenerator ausgesendeten kontinuierlichen Hochfrequenzschwingungen vollkommen gleichbleibende Amplituden besitzen, der Vorteil der Störungsfreiheit erzielt wird. Zur Beseitigung der ίο if the emitted by the tube generator continuous high-frequency oscillations have completely constant amplitudes, the advantage of freedom from interference is achieved. To eliminate the
iS Pulsationen bei mittels Gleichrichter aus Wechselstrom erzeugtem Gleichstrom ist es bereits vorgeschlagen worden, Kapazitäten parallel zum Verbrauchswiderstand auf der Gleichstromseite einzuschalten. Eine derartigeiS pulsations with by means of a rectifier Alternating current generated direct current it has already been proposed capacities to be switched on parallel to the consumption resistance on the direct current side. Such a one
to bekannte Schaltungsanordnung ist beispielsweise in Fig. ι dargestellt. Der beispielsweise 500 periodige Wechselstrom wird über einen Transformator t einem Gleichrichter g zugeführt, so daß in dem Verbrauchswiderstand r ein wellenförmiger Gleichstrom fließen würde. Um diesen Gleichstrom jedoch möglichst frei von Pulsationen zu gestalten, ist zu dem'Verbrauchswiderstand r ein Kondensator c parallel geschaltet, so daß der Wellenstrom nach Möglichkeit unterdrückt wird. Ein derartiger Kondensator muß aber, sofern die Beseitigung der Wellenströme tatsächlich eintreten soll, eine außerordentlich große Kapazität besitzen und außerdem große Dimensionen erhalten, wenn gleichzeitig eine genügende Durchschlagsfestigkeit erreicht werden soll. To known circuit arrangement is shown for example in Fig. ι. The for example 500 periodic alternating current is fed to a rectifier g via a transformer t , so that a wave-shaped direct current would flow in the consumption resistor r. However, in order to make this direct current as free from pulsations as possible, a capacitor c is connected in parallel to the consumption resistor r so that the ripple current is suppressed as far as possible. However, if the elimination of the ripple currents is actually to occur, such a capacitor must have an extraordinarily large capacitance and also have large dimensions if sufficient dielectric strength is to be achieved at the same time.
Gemäß vorliegender Erfindung wird nun zu dem gleichen Zwecke an Stelle eines einfachen Kondensators ein aus Kapazität und Selbstinduktion bestehendes System zum Röhren-. generator parallel geschaltet, das auf die Frequenz des Z.U unterdrückenden Wellenstromes abgestimmt ist. Infolgedessen bildet dieses System für diese Frequenz einen Kurzschluß, so daß der Wellenstrom nicht über den Verbrauchswiderstand (Generator) fließt.In accordance with the present invention, the same purpose is now used in place of a simple one Capacitor a system consisting of capacitance and self-induction for the tube. generator connected in parallel, which is set to the frequency of the Z.U suppressing wave current is matched. As a result, this system forms a short circuit for this frequency, so that the wave current does not have the consumption resistance (Generator) flows.
Enthält der Wellenstrom ferner Schwingungen anderer Frequenz, beispielsweise Oberschwingungen, so können diese durch ähnliche abgestimmte Systeme herausgesiebt werden, wie das bereits für die Beseitigung von Oberschwingungen aus Wechselstromkreisen oder zur Beseitigung von Kollektorschwingungen bei Gleichstrommaschinen bekannt ist.If the shaft current also contains oscillations of other frequencies, e.g. harmonics, so these can be screened out by similar coordinated systems as the one already used for the elimination of Harmonics from AC circuits or to eliminate collector vibrations is known in DC machines.
Eine beispielsweise Schaltungsanordnung ist in Fig. 2 dargestellt. Der über den Verbrauchswiderstandr (Generator^ fließende Wellenstrom wird dadurch unterdrückt, daß zu dem Widerstand ein aus Selbstinduktion S1 und Kondensator C1 bestehendes System parallel gelegt wird, das auf die Frequenz des Wellenstromes abgestimmt ist. Sowohl Kondensator wie Selbstinduktion können in ihren Abmessungen verhältnismäßig sehr klein ausgeführt werden. Führt die Kurve des Wellenstromes außerdem noch andere Schwingungen, so können dieseAn example circuit arrangement is shown in FIG. The wave current flowing through the consumption resistor (generator ^ is suppressed by the fact that a system consisting of self-induction S 1 and capacitor C 1 is placed in parallel with the resistor and is matched to the frequency of the wave current. Both capacitor and self-induction can be proportionate in their dimensions If the wave current curve also has other vibrations, then these
