Description
Die Erfindung bezieht sich auf einen Oszillator, der sich besonders zur Erzeugung von Impulsen eignet und der sich beispielsewise bei Luftlandeanlagen oder ähnlichen Einrichtungen als Zeichensender eignet.The invention relates to an oscillator which is particularly suitable for generating pulses and which is suitable, for example, as a signal transmitter in air landing facilities or similar facilities.
Zeichensender für Funksignale und für Lichtsignale sind bisher mit beweglichen mechanischen Bauteilen, wie beispielsweise Elektromotoren, Relais usw., gebaut worden. Derartige Bauteile sind der Abnutzung unterworfen und gegen mechanische Schwingungen empfindlich. Es ist daher wünschenswert, Bauteile nichtmechanischer Art vorzusehen, um auf diese Weise die Verwendung beweglicher Teile zu vermeiden.Signal transmitters for radio signals and for light signals have so far been made with movable mechanical components, such as electric motors, relays, etc., have been built. Such components are subject to wear and tear subject and sensitive to mechanical vibrations. It is therefore desirable to have components of a non-mechanical nature, in order to avoid the use of moving parts.
Es ist bereits vorgeschlagen worden, Zeichensender zu bauen, die mit Induktivitäten arbeiten, deren Kerne gesättigt werden können. Diese sind jedoch nur dann brauchbar, wenn Wechselstrom zur Verfügung steht, und sie sind des weiteren verhältnismäßig groß und Schwer. Auch die Verwendung von Impulsgeneratoren mit Elektronenröhren ist bereits bekannt. Diese haben jedoch den Nachteil, daß sie einen Verbrauch an Heiz- und Anodenstrom haben und daß sie sich besonders beim Einsatz in Elektrobojen als unpraktisch erwiesen haben, wo die Batteriespannung niedrig ist und wo es hinsichtlich der begrenzten Batteriekapazität wünschenswert ist, den Stromverbrauch auf das äußerste zu beschränken.It has already been proposed to build character transmitters that work with inductors, their cores can be saturated. However, these can only be used if alternating current is available, and they are also relatively large and heavy. Also the use of pulse generators with electron tubes is already known. However, these have the disadvantage that they consume heating and anode current and that they have proven impractical, especially when used in electric buoys where the battery voltage is low and where it is desirable in terms of limited battery capacity is to limit the power consumption to the utmost.
Es ist bereits ein Signalgenerator für automatisch arbeitende Signaleinrichtungen vorgeschlagen worden, in welchem von dem erfindungsgemäßen Impulsgenerator Gebrauch gemacht wird. Dieser Impulsgenerator selbst ist jedoch nicht Gegenstand des älteren Vorschlags. A signal generator for automatically operating signal devices has already been proposed, in which use is made of the pulse generator according to the invention. This pulse generator however, itself is not the subject of the earlier proposal.
Die Erfindung hat eine elektrische Anordnung zum Gegenstand, bei der die angeführten Nachteile durch
die Verwendung von Transistoren beseitigt werden. Mit einem zur Zeit zur Verfügung stehenden Hochleistungstransistor
kann ein Strom von 1 A oder mehr bei einem inneren Spannungsabfall von nur etwa V2 V
beherrscht werden. Ein derartiger Transistor läßt sich deshalb sehr vorteilhaft als Schaltelement für einen
z. B. mit einer Lampe belasteten Stromkreis verwenden. Als Transistor kann der Typ PNP und auch
NPN verwendet werden mit im allgemeinen drei Elektroden, einer Emitterelektrode, einer Basiselektrode und
einer Auffangelektrode. Damit die Steuerenergie so klein wie möglich gehalten werden kann, wird gewöhnlich
eine Schaltung verwendet, bei der die Emitterelektrode geerdet ist, wobei dann bei einem Transistor
des Typs PNP an die Basiselektrode gegen die Emitterelektrode eine negative Spannung angelegt wird und
bei einem Transistor des Typs NPN umgekehrt verfahren wird. Bei einem Ausführungsbeispiel, bei dem
der Kollektorstrom 1 A beträgt, muß man an die Basiselektrode einen Strom von etwa 0,1 A legen, um zwi-S
chaltungs anordnung
zur Impulserzeugung
mit zwei komplementären TransistorenThe subject of the invention is an electrical arrangement in which the stated disadvantages are eliminated through the use of transistors. With a high-power transistor currently available, a current of 1 A or more can be controlled with an internal voltage drop of only about V2 V. Such a transistor can therefore be very advantageous as a switching element for a z. B. use a circuit loaded with a lamp. The transistor type PNP and also NPN can be used with generally three electrodes, an emitter electrode, a base electrode and a collecting electrode. In order to keep the control energy as small as possible, a circuit is usually used in which the emitter electrode is grounded, in which case a negative voltage is applied to the base electrode against the emitter electrode for a transistor of the PNP type and a negative voltage for a transistor of the NPN type the reverse is done. In an embodiment in which the collector current is 1 A, a current of about 0.1 A must be applied to the base electrode in order to switch between circuitry

sehen der Auffangelektrode und der Emitterelektrode eine Spannungsdifferenz von der Größenordnung von 0,5 V zu erhalten. Wenn beispielsweise als Zeichensender für elektrische Bojen ein mit Transistoren ausgerüsteter Oszillator verwendet werden soll, stellen sich von selbst wegen des hohen erforderlichen Wirkungsgrades besondere Probleme heraus. Hierbei ist es in erster Linie notwendig, die Basiselektrode eines Hochleistungstransistors ausreichend auszusteuern, um während der einzelnen Lichtzeiten einen kleinen Spannungsabfall zu erhalten, und in zweiter Linie muß man zwischen den einzelnen Lichtzeiten einen unnötig hohen Stromverbrauch der Transistoren vermeiden, see a voltage difference of the order of magnitude of the collecting electrode and the emitter electrode 0.5V. If, for example, a signal transmitter for electric buoys is equipped with transistors Oscillator to be used make themselves because of the high required efficiency particular problems. Here it is primarily necessary to use the base electrode of a To control high-performance transistor sufficiently to generate a small one during the individual light times To get voltage drop, and in the second place one has to have one between the individual light times avoid unnecessarily high power consumption of the transistors,
DieErfindung besteht in einer Schaltungsanordnung zur Impulserzeugung mit zwei komplementären Transistoren, bei der die Steuerelektrode, z. B. die Basiselektrode, des zweiten Transistors mit der Ausgangselektrode des ersten verbunden ist, und in dem mit der Ausgangselektrode, z. B. dem Kollektor, des zweiten Transistors verbundenen Ausgangskreis ein Stromverbraucher liegt, und ist gekennzeichnet durch einen Rückkopplungskreis, der die Ausgangselektrode des zweiten Transistors mit der Steuerelektrode, z. B. der Basiselektrode, des ersten verbindet und so ausgebildet ist, daß er während der Anfangszeit eines dem Stromverbraucher zugeführten Impulses eine positive Rückkopplung erzeugt.The invention consists in a circuit arrangement for pulse generation with two complementary transistors, in which the control electrode, e.g. B. the base electrode of the second transistor with the output electrode of the first is connected, and in which with the output electrode, e.g. B. the collector, the second Transistor connected output circuit is a power consumer, and is characterized by a Feedback circuit connecting the output electrode of the second transistor to the control electrode, e.g. B. the Base electrode, the first connects and is designed so that it is the power consumer during the initial period of one applied pulse generates a positive feedback.
