Description
Es ist bekannt, zum Betrieb polarisierter Sender, wie z. B. elektromagnetischer oder magnetostriktiver Unterwasserschallsender, einen Generator zu verwenden, der außer der Sendewechseispannung auch noch die Polarisationsgleichspannung liefert. It is known to operate polarized transmitters such. B. electromagnetic or magnetostrictive underwater sound transmitter to use a generator that In addition to the alternating transmission voltage, it also supplies the DC polarization voltage.
Die Polarisationsgleichspannung wurde dabei durch einen Gleichrichter mit Glättungsmittel erzeugt, und zwar wurden dabei die Wechselspannung und die Gleichspannung getrennt hergestellt, beispielsweise zwei parallelen Sekundärspulen entnommen und dem Sender über eine Weiche zugeführt. Diese Anordnung erforderte einen verhältnismäßig großen Aufwand.The polarization DC voltage was thereby through a rectifier generated with smoothing agent, namely the alternating voltage and the direct voltage manufactured separately, for example, two parallel secondary coils removed and fed to the transmitter via a switch. This arrangement required a proportionate great effort.
Gemäß der Erfindung wird dieselbe Aufgabe ein facher dadurch gelöst, daß die Generatoranordnung aus einem Generator, beispielsweise Impulsgenerator, mit halber Sendefrequenz und einem Zweiweggleichrichter mit Glättungsmittel besteht, das derart unvollständig glättend bemessen ist, daß ein Wechselstrom mit Gleichstromkomponente entsteht; dieser wird dem Sender unmittelbar zugeführt, wobei die Gleichstromkomponente zur Polarisation und die Wechselstromkomponente zur Erregung des Senders dient. Beide Spannungen werden also gleichzeitig erzeugt. According to the invention, the same object is achieved in a multiple way by that the generator arrangement consists of a generator, for example a pulse generator, with half the transmission frequency and a full-wave rectifier with smoothing means, which is dimensioned so incompletely smoothing that an alternating current with a direct current component arises; this is fed directly to the transmitter, with the direct current component serves for polarization and the alternating current component for excitation of the transmitter. Both voltages are generated at the same time.
In der Zeichnung ist eine Ausführungsform der Einrichtung nach der Erfindung beispielsweise dargestellt. In the drawing is an embodiment of the device according to Invention shown for example.
Abb. I zeigt die Schaltung und Abb. 2 den Verlauf der erzeugten Spannung. Fig. I shows the circuit and Fig. 2 shows the course of the generated voltage.
I bedeutet einen über einen Kondensator C und eine Spule S rückgekoppelten Generator, der auf die halbe Sendefrequenz eines Senders 2 abgestimmt ist. I means one that is fed back via a capacitor C and a coil S. Generator that is tuned to half the transmission frequency of a transmitter 2.
Die erzeugte Hochfrequenzspannung wird über einen Transformator 3 einem Zweiweggleichrichter-4 zugeführt, der aus der Hochfrequenzspannung einen Spannungsverlauf gemäß der gestrichelten Kurve 5 erzeugt. Zwischen dem Gleichrichter 4 und dem Sender 2 liegt ein Glättungskondensator 6.The generated high-frequency voltage is transmitted via a transformer 3 a full-wave rectifier-4 is supplied, which from the high-frequency voltage a voltage curve generated according to the dashed curve 5. Between the rectifier 4 and the transmitter 2 is a smoothing capacitor 6.
Normalerweise ist ein derartiger Kondensator derart bemessen, daß ein vollständiger Gleichstrom entsteht, der bei den bekannten Anordnungen zur Polarisation des Senders diente. Hierbei war daml eine besondere Herstellung der Hochfrequenzspannung notwendig, die dem Sender über eine Weiche besonders zugeführt werden mußte. Erfindungsgemäß wird dies dadurch überflüssig, daß der Kondensator 6 derart unvollständig glättend bemessen ist, daß sich ein Spannungsverlauf gemäß der ausgezogenen Kurve 7 ergibt. Hierdurch erhält man eine Hochfrequenzspannung doppelter Frequenz, die den Sender unmittelbar erregt, mit einer Gleichstromkomponente P, die. zur Polarisation dient.Usually such a capacitor is dimensioned such that a complete direct current arises, which in the known arrangements for polarization of the transmitter served. At that time there was a special production of high frequency voltage necessary, which had to be specially fed to the transmitter via a switch. According to the invention this becomes superfluous because the capacitor 6 is so incompletely smoothing is dimensioned so that a voltage curve according to the solid curve 7 results. This gives a high-frequency voltage twice the frequency that the transmitter immediately excited, with a direct current component P, the. serves for polarization.
Es ist zu beachten, daß sich der in Abb. 2 dargestellte Spannungsverlauf entsprechend ab ändert, wenn der Generator I übersteuert und dadurch als Impulsgenerator benutzt wird. It should be noted that the voltage curve shown in Fig. 2 changes accordingly when the generator I overdrives and thus as a pulse generator is used.
