Description
DEUTSCHESGERMAN
Die Erfindung betrifft einen Wechselstromgenerator, der durch eine Gleichspannung gesteuert wird.The invention relates to an alternator which is controlled by a direct voltage.
Bekannte Einrichtungen dieser Art sind entweder als elektromechanische Zerhacker oder als impulsgetastete Röhrensender ausgebildet.Known devices of this type are either as electromechanical chopper or as pulse-controlled Tube transmitter trained.
So ist z. B. eine Schaltungsanordnung zur Anzeige des Ladungszustandes einer Spannungswelle bekannt, bei welcher nach Absinken der Batteriespannung unter den Sollwert automatisch eine von der Batterie gespeiste Kippschaltung mit spannungsabhängiger Kippfrequenz gemodelt wird, deren Kippfrequenz somit ein Maß für die Batteriespannung ist.So is z. B. a circuit arrangement for displaying the state of charge of a voltage wave is known, in which, after the battery voltage has dropped below the setpoint, one automatically fed by the battery Trigger circuit is modeled with voltage-dependent trigger frequency, the trigger frequency of which is thus a Measure for the battery voltage.
Ferner wurde bereits vorgeschlagen bei einer Schaltungsanordnung zur Erzeugung von Wechselspannungsimpulsen mit einem selbstschwingenden Multivibrator, dessen einen Arbeitswiderstand durch einen selbsterregten oder fremdgesteuerten Wechselspannungsgenerator zu ersetzen, indem seine Anschlußpunkte mit den Speisepunkten des Generators verbunden werden.Furthermore, it has already been proposed in a circuit arrangement for generating alternating voltage pulses with a self-oscillating multivibrator, one of which has a working resistance to replace a self-excited or externally controlled alternating voltage generator by removing its connection points be connected to the feed points of the generator.
Diese Anordnungen haben den Nachteil, daß die Schwellspannungen für die Ein- und Ausschaltung des Wechselstromerzeugers unbestimmte Werte aufweisen. Für Zwecke der elektronischen Schalttechnik sind jedoch Einrichtungen erforderlich, deren Werte für die Ein- und Ausschaltspannung genau bestimmbar sind.These arrangements have the disadvantage that the threshold voltages for switching on and off the Alternator have indefinite values. For purposes of electronic switching technology, however Equipment is required whose values for the switch-on and switch-off voltage can be precisely determined.
Um diese Nachteile zu vermeiden, wird bei einem durch eine Gleichspannung tastbaren Wechselstromgenerator unter Verwendung von Transistoren erfindungsgemäß vorgeschlagen, daß der Wechselstromgenerator aus einem in Basisschaltung arbeitenden Transistor besteht, der gleichzeitig Bestandteil einer aus zwei emittergekoppelten Trasistoren bestehenden Kippschaltung ist.In order to avoid these disadvantages, an alternating current generator with the use of transistors which can be sensed by a direct voltage is according to the invention proposed that the alternator from a working in basic circuit There is a transistor, which is also part of a transistor consisting of two emitter-coupled transistors Toggle is.
Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung. Als Kippschaltung für die Steuerung des Generators wird ein sogenannter »Schmitt-Trigger« verwendet. Dieser besteht aus den beiden Transistoren, Ts1 und Ts2, die einen gemeinsamen Emitterwiderstand R3 aufweisen.The figure shows an embodiment of the invention. A so-called »Schmitt trigger« is used as a flip-flop to control the generator. This consists of the two transistors, Ts 1 and Ts 2 , which have a common emitter resistor R 3 .
Der Schmitt-Trigger kann je nach Steuerung an der Eingangselektrode eine von zwei stabilen Lagen einnehmen. Irgndwelche Zwischenstellungen sind bei dieser Anordnung nicht möglich. Wird eine bestimmte Ansprechschwelle, welche durch die Dimensionierung bestimmt wird, überschritten, so springt die Schaltung von der einen stabilen Lage in die andere. Sie springt wieder zurück in die erste Lage, wenn die Ansprechschwelle um einen bestimmten Betrag unterschritten wird. Die Werte, die das Hin- und Zurückkippen bewirken, sind um einen geringen Betrag verschieden.Depending on the control on the input electrode, the Schmitt trigger can assume one of two stable positions. Any intermediate positions are not possible with this arrangement. Will a certain If the response threshold, which is determined by the dimensioning, is exceeded, the circuit jumps from one stable position to the other. It jumps back to the first position when the response threshold is undercut by a certain amount. The values that cause tipping back and forth are different by a small amount.
Im Ruhezustand der Einrichtung, d. h. wenn dem Transistor Ts1 an den Klemmen a, b keine Steuerspannung zugeführt wird, ist die Basis des Transistors Hochfrequenz -TastschaltungWhen the device is idle, ie when no control voltage is fed to the transistor Ts 1 at the terminals a, b , the base of the transistor is a high-frequency key circuit

Wenn an den Klemmen a, b bezüglich der Basis des Transistors Tj1 eine positive Steuerspannung auftritt, die größer ist als die Ansprechspannung, so wird der Strom gesperrt. Dadurch verändert sich die Basisspannung für den Transistor Ts2, so daß dieser stromleitend wird. Dieser Zustand bleibt bestehen, bis die Abfallspannung an den Klemmen a, b unterschritten und der Ausgangszustand wiederhergestellt wird.If a positive control voltage occurs at the terminals a, b with respect to the base of the transistor Tj 1 which is greater than the response voltage, the current is blocked. This changes the base voltage for the transistor Ts 2 , so that it becomes conductive. This state remains until the voltage drops below the dropout voltage at terminals a, b and the initial state is restored.
In der vorliegenden Anordnung bewirkt der Transistor Tj2 nicht nur eine Kippsteuerung, sondern er dient auch als Schwingungserzeuger. Mit der Primärwicklung des Übertragers Ü und den Kondensatoren C1 bis C4 bildet der Transistor Tj2 einen Dreipunktgenerator, wobei dieser in Basisschaltung betrieben wird. Der Schwingungszustand dieses Generators ist erreicht, wenn an den Klemmen a, b die Ansprechspannung überschritten und der Transistor Tj2 stromleitend wird.In the present arrangement, the transistor Tj 2 not only effects tilt control, but also serves as a vibration generator. With the primary winding of the transformer U and the capacitors C 1 to C 4 , the transistor Tj 2 forms a three-point generator, which is operated in a base circuit. The oscillation state of this generator is reached when the response voltage is exceeded at the terminals a, b and the transistor Tj 2 becomes conductive.
Im Ausgangskreis des Transistors Tj2 wird die Schwingenergie durch den Transformator Ü ausgekoppelt. An den Klemmen c, d kann die Sekundärwicklung des Übertragers entweder mit einem Verstärker oder mti einem Gleichrichter verbunden sein. Die entnommene Schwingleistung kann dazu dienen, ein elektromagnetisches oder ein elektronisches Relais zu steuern. Die Ausgansspannung kann durch geeignete Bemessung des Übertragers beliebig gewählt werden. Wenn die beschriebene Einrichtung als Relais verwendet wird, so bietet sie den Vorteil, daß der Steuerstromkreis durch den Übertrager Ü vom Schalt-In the output circuit of the transistor Tj 2 , the oscillation energy is decoupled by the transformer Ü. At terminals c, d , the secondary winding of the transformer can either be connected to an amplifier or to a rectifier. The extracted vibration power can be used to control an electromagnetic or an electronic relay. The output voltage can be chosen arbitrarily by suitable dimensioning of the transformer. If the device described is used as a relay, it has the advantage that the control circuit through the transformer Ü from the switching
