Der kapazitive Spannungswandler setzt sich, wie in der Zeichnung dargestellt, aus dem kapazitiven Spannungsteiler C1ZC2 und einem Zwischenkreis zusammen. Der Zwischenkreis besteht aus der Resonanzdrossel Dr mit konstanter Induktivität und dem HiI f swandler Sp (MittelspanmungBwandler), auf dessen Sekundärseite die Bürde B angeschlossen ist. Außerdem sind unter Umständen noch weitere hier nicht interessierende Schaltelemente vorgesehen.As shown in the drawing, the capacitive voltage converter consists of the capacitive voltage divider C 1 ZC 2 and an intermediate circuit. The intermediate circuit consists of the resonance choke Dr with constant inductance and the Hi-Fi converter Sp (medium voltage converter), on whose secondary side the burden B is connected. In addition, other switching elements that are not of interest here may also be provided.

Bei einem solchen Wandler kann der Fall eintreten, daß bei Einleitung von Schaltvorgängen, z. B. bei hochspannungsseitiger Einschaltung des Wandlers oder nach erfolgtem Sekundärkurzschluß usw., Kippschwingungen angeregt werden, welche dazu führen, daß am unteren Teil das kapazitiven Spannungsteilers unzulässig hohe Spannungen und demzufolge auch hohe Ströme im angeschlossenen induktiven Zwischenkreis auftreten. Letzteres kann auch eintreten, wenn sekundärseitig starke Überlastungen bzw. Kurzschlüsse auftreten, ohne daß Kippschwingungen angeregt werden.With such a converter, the case may arise that when initiating switching operations, eg. B. at Switching on the converter on the high voltage side or after a secondary short circuit, etc., relaxation oscillations are excited, which lead to the lower part of the capacitive voltage divider Inadmissibly high voltages and consequently also high currents in the connected inductive intermediate circuit appear. The latter can also occur if there are severe overloads or short circuits on the secondary side occur without tilting vibrations being excited.

Um das Auftreten hoher Spannungen im obigen Sinne zu verhindern, ist erfindungsgemäß die Resolianzdrossel mit einer Sekundärwicklung zum Anschluß einer weiteren derart bemessenen Drossel mit geschlossenem Eisenweg ausgerüstet, daß ihre Induktivität mit steigendem Strom infolge Sättigung abnimmt. In order to prevent the occurrence of high voltages in the above sense, the resolution choke is according to the invention with a secondary winding for the connection of a further choke dimensioned in this way equipped closed iron path that their inductance decreases with increasing current due to saturation.

In der Zeichnung ist ein Schemabild wiedergegeben. Treten hierbei durch irgendwelche Schaltvorgänge Kippschwingungen, auf, so wird die Drossel Dr1 infolge der induktiven Übertragung des im Zwischenkreis fließenden erhöhten Stromes durch einen größeren Strom als im Nbrmalbetrieb magnetisiert, was dazu führt, daß infolge der erfxndungsgemäßen Ausbildung der Drossel Dr1 ihre Induktivität abnimmt. Durch diese Induktivitätsabnahme tritt eine Verstimmung des Zwischenkreises ein, so daß die Spannung am unteren Teil des kapazitiven Spannungsteilers C2 stark abnimmt. Das hat zur Folge, daß sich Kapazitiver SpannungswandlerA schematic diagram is shown in the drawing. Occur in this case by any switching operations relaxation oscillations on, the throttle Dr 1 is a result of the inductive transmission of the current flowing in the intermediate circuit increased current as magnetized by a larger current in Nbrmalbetrieb, with the result that due to the erfxndungsgemäßen forming the throttle Dr 1 decreases its inductance . This decrease in inductance causes a detuning of the intermediate circuit, so that the voltage at the lower part of the capacitive voltage divider C 2 decreases sharply. This has the consequence that capacitive voltage converter
