Description

Anordnung zur- Glät'tung der Strom- und Spannungskurve bei Umrichtern Es ist bekannt, bei Umrichtern den um-_ treformten Wechselstrom zü glätten, bevor er dem Verbraucher zugeführt wird. ' Diesem Zweckdienende Glättungsdrosselspulen können entweder zwischen Umrichter und Verbraucher liegen oder auch innerhalb der Umrichterschaltung, d. h. ohne galvanische Verbindung mit dem Verbraucherkreis, geschaltet sein. Die letztgenannte- Schaltung hat den Vorteil; daß die Glättungsdrösseln an einer solchen Stelle in die Umrichterschaltung eingefügt werden k_ önnen, an der die Spannung verhältnismäßig klein ist. Bei; einer bekannteil Schaltung -dieser Art liegt beispiefswese je eine. Drosselspule zwischen einer Kathode eines an der UmrichtunZ beteiligten Entladungsgefäßes und den Endklemmen der Primärwicklung des Ausgangstransformators.Arrangement for smoothing the current and voltage curve in converters It is known to smooth the converted alternating current in converters before it is fed to the consumer. Smoothing reactors used for this purpose can either be between the converter and the consumer or within the Converter circuit, d. H. without galvanic connection with the consumer circuit, be switched. The latter circuit has the advantage; that the smoothing rods can be inserted into the converter circuit at such a point which the voltage is relatively small. At; a well-known circuit - this one Type is for example one each. Choke coil between a cathode one to the UmrichtunZ involved discharge vessel and the end terminals of the primary winding of the Output transformer.

Gegenstand der Erfindung ist eine Verbesserung der innerhalb der Umrichterschaltwng eingefügten Glättimgsmittel. Erfindungsgemäß sind die Wicklungen der Glättungsdrosseln derart ,geschaltet, daß der ihnen gemeinsanie Eisenkreis von den beiden Halbwellen des umgeformten Wechselstromes im entgegengesetzten Sinne erregt wird. Da shat zur Folge, daß der Magnetkreis der Drosselspule genau so erregt wird wie eirie in einem normalen Wechselstromkreis liegende Drosselspule. Die -Drosselspule wird bei dieser Schaltung bei gleicher Wirkung wesentlich kleiner und daher billiger.The subject of the invention is an improvement in the converter circuit inserted smoothing agent. According to the invention, the windings of the smoothing chokes switched in such a way that the iron circle common to them is formed by the two half-waves of the converted alternating current is excited in the opposite sense. Da shat for As a result, the magnetic circuit of the choke coil is excited exactly as it is in one normal AC circuit inductor. The choke coil is used in this Circuit much smaller and therefore cheaper with the same effect.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die beiden Enfadungsstreckengruppen eines Umrichters sind mit r und 2 bezeichnet. Die Kathoden 3 und 4 sind an die Klemmen der Primärwicklung 5 des Ausgangstransformators 6 angeschlossen.An exemplary embodiment of the invention is shown in the drawing. The two discharge path groups of a converter are denoted by r and 2. The cathodes 3 and 4 are connected to the terminals of the primary winding 5 of the output transformer 6 connected.

In jeder Kathodenleitung ist ein Teil der Glättt%ngsinduktivität 7 eingefügt, und zwar derart, daß die beiden Spulen. von den beiden Halbwellen des umgeformten Wechsels.tromes des Umrichters in entgegengesetztem Sinne durchflassen bzw. erregt werden.Part of the smoothing inductance 7 is in each cathode line inserted in such a way that the two coils. of the two half-waves of the The converted alternating currents of the converter flow through in the opposite direction or are excited.

Soweit bei bekannten Stromrichterschaltungen ,die beyden Spulen einer Drosselspule in entgegengesetztem Sinne von. Strömen durchflossen werden dienen diese- Spulen einem anderen Zweck als bei der Erfindung. Die Drosselspule der bekannten Gleichrichterscbaltungen mit Saugdrosselspule soll beispielsweise die Stromführung benachbarter Anoden verlängern. Es handelt sich demnach nicht um eine wechselstromerregte Drosselspule in einer Umrichterschaltung im Sinne der-Erfindung.As far as known converter circuits, the two coils one Choke coil in the opposite sense of. Streams flowed through will serve these coils have a different purpose than that of the invention. The inductor of the well-known Rectifier circuits with suction throttle coil should, for example, conduct the current of neighboring anodes. It is therefore not an AC excited Choke coil in a converter circuit within the meaning of the invention.
