Description

Einen tlbertrager enthaltender Vierpol Die Erfindung betrifft einen einen übertrager enthaltenden Vierpol zur Beseitigung von Störspannungen, welche die Nutzwechselspannungen wesentlich überschreiten.A quadrupole containing a transformer The invention relates to a a transformer containing four-pole to eliminate interference voltages, which the useful alternating voltages significantly exceed.

Erfindungsgemäß ist bei einer derartigen Anordnung zur Eingangsseite des Übertragers die Reihenschaltung eines mit wachsender Stromstärke fallenden Widerstandes und einer Impedanz, die gleichzeitig mit der Ausgangs-,vdcklung des Übertragers in Reihe liegt, parallel geschaltet und der Wicklungssinn des tibertragers so gewählt, däß die an der Impedanz auftretende Störspannung den im Verbraucherkreis noch vorhandenen Störspannungen entgegengesetzt gerichtet ist.According to the invention is with such an arrangement to the input side of the transformer is the series connection of a resistor that decreases with increasing current strength and an impedance that is simultaneous with the output coverage of the transformer is in series, connected in parallel and the direction of winding of the transformer is selected so that the interference voltage occurring at the impedance corresponds to that which is still present in the consumer circuit Interference voltages is directed in the opposite direction.

Es sind bereits Vierpole bekannt, bei denen die aus einem Querkreis abgeleitete Störspannung dazu benutzt ist, an einer mit dem Verbraucher in Reihe liegenden Impedanz eine Spannung hervorzurufen, die der dort noch vorhandenen Störspannung entgegengesetzt gerichtet ist. Dort handelte es sich aber nicht um Anordnungen, die zur Beseitigung von Störspannungen bestimmter Amplituden, sondern bestimmter Frequenzen dienen.Quadrupoles are already known in which those from a transverse circle derived interference voltage is used on one with the consumer in series lying impedance to produce a voltage that is the same as the interference voltage that is still present there is directed in the opposite direction. But there were no orders those for eliminating interference voltages of certain amplitudes, but rather certain ones Frequencies serve.

Bei dem Ausführungsbeispiel eines Vierpoles nach der Erfindung entsprechend der Abbildung ist als Nutzsystem ein Telefon g angenommen, dem über einen Transformator i i die Spannung eines Empfängers zugeführt wird. Die Primärseite dieses Transformators ist nun über die Reihenschaltung eines mit wachsender Stromstärke fallenden Widerstandes 12, z. B. eines Trockengleichrichters in einer Schaltung, in der der Strom vom neutralen Metall durch die Sperrschicht zum Halbleiter fließt, und einer Impedanz 15 überbrückt. Diese Impedanz wird vorzugsweise so ausgebildet, daß sie rein Ohmschen Charakter besitzt. Der Spannungsabfall an der Impedanz 15 wirkt infolge der Reihenschaltung dieser Impedanz mit der Sekundärwicklung des Übertragers' i i auf den Stromkreis des Telefons q ein. Bei richtiger Wahl der Polaritäten des Widerstandes 15 wirkt dessen Spannung der im Nutzsystem g enthaltenen Störspannung entgegen und kompensiert sie weitgehend.In the embodiment of a four-pole according to the invention accordingly In the figure, a telephone g is assumed to be the useful system, which has a transformer i i the voltage of a receiver is supplied. The primary side of this transformer is now via the series connection of a resistance that decreases with increasing current strength 12, e.g. B. a dry rectifier in a circuit in which the current from the neutral Metal flows through the barrier layer to the semiconductor, and an impedance 15 is bridged. This impedance is preferably designed so that it is purely ohmic in character owns. The voltage drop across the impedance 15 acts as a result of the series connection this impedance with the secondary winding of the transformer 'i i on the circuit of the telephone q a. With the correct choice of the polarities of the resistor 15 acts its voltage counteracts and compensates for the interference voltage contained in the useful system g they largely.

Statt eines Ohmschen Widerstandes 15 kann auch ein induktiver oder kapazitiver Widerstand verwendet werden, je nach der erforderlichen Phasenlage, die eine günstigste Kompensation der Störfrequenz bewirkt. Zwischen den Widerstand 15 und das Nutzsystem kann auch ein zusätzlicher Übertrager geschaltet werden, der den Widerstand 15 völlig ersetzen kann.Instead of an ohmic resistor 1 5, a inductive or capacitive resistance can be used depending on the required phase position, which causes a favorable compensation for the disturbance frequency. An additional transformer, which can completely replace the resistor 15, can also be connected between the resistor 15 and the useful system.
