Description

DEUTSCHESGERMAN

Bei den bekannten Anordnungen zum Schalten von Wechselstromkreisen mittels Geichrichtern liegen die Gleichrichter in den beiden Wechselstrom führenden Adern, und die Gleichspannung wird über die Mittelabgriffe der von vor oder hinter den Gleichrichtern liegenden Drosselspulen oder Transformatorenwicklungen angelegt. Diese Anordnungen stellen erhebliche Anforderungen an die Übereinstimmung der verwendeten Gleichrichter, um die Symmetrie des Wechselstromkreises nicht zu verschlechtern. Bei der Steuerung der Eigenschaften der Gleichrichter üblicher Fertigung müssen die Gleichrichter, die sich in jedem möglichen Schaltzustand elektrisch gleich verhalten, durch einen besonderen Auswahlvorgang gefunden werden.In the known arrangements for switching AC circuits by means of rectifiers are the Rectifier in the two cores carrying alternating current, and the direct voltage is via the center taps of inductors or transformer windings upstream or downstream of the rectifiers created. These arrangements place considerable demands on the conformity of the used Rectifier, so as not to deteriorate the symmetry of the AC circuit. In the control Of the characteristics of the rectifiers of conventional manufacture, the rectifiers that are in every possible need Switching state behave electrically the same, can be found by a special selection process.

Die Erfindung bezweckt, die Schwierigkeiten zu vermelden, und erreicht dies dadurch, daß zwei Wicklungen eines ersten Übertragers in ihrem Symmetriepunkt über den Kollektor und den Emitter eines symmetrischen Transistors hintereinandergeschaltet sind und daß zwischen der Basis des Transistors und dem Symmetriepunkt der Wicklungen eines zweiten Übertragers zwei Spannungsquellen verschiedener Polung geschaltet sind, die durch den Schalter wahlweise derart an die Basis des Transistors angelegt werden können, daß dieser entweder leitend oder gesperrt ist. Die Erfindung faßt somit die beiden Gleichrichter der bekannten Schaltungen zu einem gemeinsamen Schaltelement zusammen. Zwei sich entsprechende Elektroden der einzelnen Gleichrichter bilden nunmehr eine gemeinsame Elektrode, die in dem Symmetriepunkt von zwei Drosselspulen oder Transistoren liegt. Als neues Schaltelement verwendet die Erfindung einen Transistor, dessen Emitter-Basis-Strecke sich ebenso verhält wie die Kollektor-Basis-Strecke.The invention aims to report the difficulties and achieves this by having two windings of a first transformer in their point of symmetry are connected in series via the collector and the emitter of a symmetrical transistor and that between the base of the transistor and the symmetry point of the windings of a second transformer two voltage sources of different polarity are connected, which can be switched on by the switch the base of the transistor can be applied so that it is either conductive or blocked. The invention thus combines the two rectifiers of the known circuits to form a common switching element. Two corresponding electrodes of the individual rectifiers now form a common one Electrode that lies in the symmetry point of two inductors or transistors. As a new one Switching element, the invention uses a transistor, the emitter-base path of which behaves in the same way like the collector-base route.

Die Schaltung nach der Erfindung hat gegenüber den bekannten Anordnungen den Vorteil, daß nur ein Bauelement benötigt wird, bei welchem die Symmetriebedingungen besonders leicht eingehalten werden können, weil Emitter- und Kollektor des Transistors an einen gemeinsamen Kristallbereich grenzen.The circuit according to the invention has the advantage over the known arrangements that only one Component is required in which the symmetry conditions can be met particularly easily, because the emitter and collector of the transistor adjoin a common crystal area.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Diese zeigt eine Schaltung zur Kopplung zweier Leitungsabschnitte A und B. An embodiment of the invention is shown in the drawing. This shows a circuit for coupling two line sections A and B.

Der Übertrager UA verbindet den Leitungsabschnitt A mit der Schaltstrecke C. Der Übertrager UB verbindet den Leitungsabschnitt B mit der Schaltstrecke C. Die an der Schaltstrecke C liegenden Wicklungen UAl und UA2 sind mit dem Emitter bzw. dem Transistorschalter
für Wechselstromkreise
The transformer UA connects the line section A with the switching path C. The transformer UB connects the line section B with the switching path C. The windings UAl and UA2 lying on the switching path C are connected to the emitter or the transistor switch
for AC circuits

Kollektor eines Transistors T verbunden. Die entsprechenden Wicklungen UBl und UB 2 des Übertragers UB sind miteinander sowie mit einem Steuerkontakt 6" verbunden. Dieser Steuerkontakt vermag wahlweise eine der Batterien Bl und 52 einzuschalten, welche mit entgegengesetzter Polung an der mit der Basis des Transistors verbundenen Steuerleitung L liegen. Je nach der Lage des Kontaktes S liegt in dem über die Leitungen des Steuerabschnittes C gebildeten Simultanstromkreis eine den Transistor T sperrende oder öffnende Spannung. Ist der Transistor T gesperrt, dann können keine Wechselströme aus dem Leitungsabschnitivi nach dem Leitungsabschnitt B über den Leitungsabschnitt C übertragen werden. Eine Übertragung ist nur möglich, wenn der Transistor T auf Durchlaß geschaltet ist, weil nur in diesem Fall die Übertragerwicklungen UAl und UA2 in Reihe liegen.Collector of a transistor T connected. The corresponding windings UBl and UB 2 of the transformer UB are connected to one another and to a control contact 6 ″. This control contact can optionally switch on one of the batteries B1 and 52, which are connected to the control line L connected to the base of the transistor with opposite polarity the position of contact S lies in the formed via the lines of the control portion C simultaneous circuit comprises a transistor T blocking or open voltage When the transistor T is cut off., then no change of currents may be selected from the Leitungsabschnitivi after the line section B via the line section C are transmitted. a Transmission is only possible when the transistor T is switched on, because only in this case the transformer windings UAl and UA2 are in series.
