Abstract

Spannungsgesteuerter Resonanzkreis nach Patent 10 2007 029 998, dadurch gekennzeichnet, dass die elektromechanischen Relais von spannungsgesteuerten elektronischen Schaltern mit elektrischer Entkopplung ersetzt werden.Voltage-controlled resonance circuit according to patent 10 2007 029 998, characterized in that the electromechanical relays are replaced by voltage-controlled electronic switches with electrical decoupling.

Description

Die Erfindung bezieht sich auf die Abstimmung von Resonanzkreisen und betrifft insbesondere die automatische Steuerung der Resonanzfrequenz. Die Erfindung ist Vervollkommnung der Erfindung nach dem Patent 10 2007 029 998.The invention relates to the tuning of resonant circuits and in particular relates to the automatic control of the resonant frequency. The invention is perfection of the invention according to the patent 10 2007 029 998.

Nachteil der bekannten Vorrichtung ist Trägheit der Durchstimmung, die von Trägheit der elektromechanischen Relais bedingt ist.Disadvantage of the known device is inertia of the tuning, which is due to inertia of the electromechanical relay.

Aus der DE 43 29 705 A1 ist ein Beispiel für einen diskontinuierlich abstimmbaren Resonanzkreis, bei dem die einzelnen Schwingkreiskapazitäten oder -induktivitäten mittels elektronischer Schalter zu- bzw. abgeschaltet werden, bekannt.From the DE 43 29 705 A1 is an example of a discontinuously tunable resonant circuit in which the individual resonant circuit capacitances or inductances by means of electronic switches on or off, known.

Zweck der Erfindung ist es, den erwähnten Nachteil zu beseitigen.The purpose of the invention is to eliminate the mentioned disadvantage.

Das Problem wird durch die Merkmale des Patentanspruchs gelöst.The problem is solved by the features of the claim.

Zweck der Erfindung dadurch gelöst, dass die elektromechanischen Relais von spannungsgesteuerten elektronischen Schaltern mit elektrischer Entkopplung ersetzt werden. Spannungsgesteuerte elektronische Schalter mit elektrischer Entkopplung sind in der technischen Literatur beschrieben (Elemente der angewandten Elektronik. E. Böhmer, D. Ehrhardt, W. Oberschelp. 15 Auflage, 2007, S. 127, Bild 2; Halbleiter-Schaltungstechnik. U. Tietze, Ch. Shenk. 11. Auflage, 1999, S. 1008, Tab. 17.1). Man macht den Ersatz laut Schaltbild (1).Purpose of the invention achieved in that the electromechanical relays are replaced by voltage-controlled electronic switches with electrical decoupling. Voltage-controlled electronic switches with electrical decoupling are described in the technical literature (Elements of Applied Electronics, E. Böhmer, D. Ehrhardt, W. Oberschelp, 15 Edition, 2007, p. 127, Figure 2, Semiconductor Circuit Technology, U. Tietze, Ch. Shenk. 11th Edition, 1999, p. 1008, Table 17.1). Man makes the replacement according to the diagram ( 1 ).
