Description
Gleichrichter mit Gegenkopplung auf einen vorgeschalteten Verstärker Die Erfindung betrifft einen Gleichrichter mit Gegenkopplung auf einen vorgeschalteten Verstärker. Gemäß der Erfindung enthält der Ausgang des Verstärkers zwei parallele Wege mit entgegengesetzt gepolten Gleichrichterelementen. Der Differenzstrom beider Wege oder der Strom eines Weges speist den Gleichstromverbraucher, und der Summenstrom beider Wege ist zur Gegenkopplung auf eine oder mehrere Stufen des Verstärkers benutzt.Rectifier with negative feedback to an upstream amplifier The invention relates to a rectifier with negative feedback to an upstream one Amplifier. According to the invention, the output of the amplifier contains two parallel Paths with oppositely polarized rectifier elements. The differential current of both Paths or the current of one path feeds the direct current consumer, and the total current Both ways are used for negative feedback on one or more stages of the amplifier.
Bei der Anordnung nach der Erfindung ist der erfindungsgemäß zusammengesetzte Gleichrichter mit einer oder mehreren vorgeschalteten Verstärkerstufen zu einem Gegenkopplungskreis derart zusammengeschaltet, daß Gleichrichter und Verstärker gleichzeitig durch eine gemeinsame Gegenkopplung entzerrt werden. Es ist zwar bereits ein Röhrengleichrichter bekannt, dessen gleichgerichteter Strom auf den Eingang des Gleichrichters gegengekoppelt ist. Diese bekannte Anordnung enthält jedoch keinen vorgeschalteten Verstärker, der durch die Gegenkopplung des Gleichrichters gleichzeitig linearisiert wird. .In the arrangement according to the invention, the one according to the invention is composite Rectifier with one or more upstream amplifier stages to one Negative feedback circuit interconnected in such a way that rectifier and amplifier be equalized at the same time by a common negative feedback. It is already a tube rectifier known whose rectified current to the input of the rectifier is fed back. However, this known arrangement does not include one upstream amplifier, which by the negative feedback of the rectifier at the same time is linearized. .
Bei der Anordnung nach der Erfindung besteht der Gleichrichter aus zwei parallel geschalteten Gleichrichterelementen oder -elementengruppen, die entgegengesetzt gepolt sind. Der Gleichrichter ist dadurch in beiden Richtungen, also für Wechselströme, durchlässig, so daß der den Gleichrichter durchfließende Verstärkerausgangsstrom zur Gegenkopplung auf eine vorhergehende Verstärkerstufe benutzt werden kann, z. B. indem man den Spannungsabfall an einem von ihm durchflossenen Widerstand zur Steuerung einer vorhergehenden Verstärkerröhre benutzt. Der Gleichstromverbraucher wird dabei von dem Strom einer Gleichrichtergruppe oder von dem Differenzstrom beider Gleichrichtergruppen gespeist. Durch die Gegenkopplung des den Gleichrichter durchfließenden Summenstroms werden die durch Inkonstanz des Gleichrichterwiderstands hervorgerufenen und die im Verstärker entstehenden Verzer rungen herabgesetzt.In the arrangement according to the invention, the rectifier consists of two rectifier elements or groups of elements connected in parallel that are opposite are polarized. The rectifier is thus in both directions, i.e. for alternating currents, permeable, so that the amplifier output current flowing through the rectifier can be used for negative feedback to a previous amplifier stage, e.g. B. by having the voltage drop traversed by one of it resistance used to control a previous amplifier tube. The direct current consumer is based on the current of one rectifier group or on the differential current of both Rectifier groups fed. Due to the negative feedback of the flowing through the rectifier Total currents are those caused by the inconsistency of the rectifier resistance and the distortions generated in the amplifier are reduced.
Bei der Aufteilung des Summenstroms in die beiden entgegengesetzt gerichteten Teilströme können neue Verzerrungen nur auftreten, wenn die benutzten Gleichrichterelemente nicht rückstromfrei sind.Opposite when dividing the total current into the two directed partial currents, new distortions can only occur if the used Rectifier elements are not free of reverse current.
