Description
Einrichtung zur Umwandlung von Gleichstrom in solchen anderer Spannung Zusatz zum Patent 436 825 Gegenstand des Patents 436 825 isst eine Anordnung zur Umformung von Gleichstrom in solchen anderer Spannung. Dabei wird der Gleichstrom mittels gittergesteuerter Entladungsstreck.-n in Wechselstrom umgewandelt. Die Spannung dieses Wechselstromes wird durch einen Transformator entsprechend dem gewünschten Spannungsverhältnis geändert und der so erhaltene Wechselstrom mit Hilfe zweier ungesteuerter Entladungsstrecken in Gleichstrom zurückverwandelt. Die in üblicher Weise in den primären. und sekundären Gleichstromkreis ;geschalteten Drosseln sind dabei derart miteinander gekoppelt, daß die die Drosselspülen durchfließenden Gleichströme in ihnen entgegengesetzte, einander aufhebende Magnetisierumgen hervorrufen.Device for converting direct current into other voltage Addendum to Patent 436 825 The subject of patent 436 825 is an arrangement for Conversion of direct current into such a different voltage. This is the direct current converted into alternating current by means of grid-controlled discharge paths. The voltage this alternating current is supplied by a transformer according to the desired Changed voltage ratio and the alternating current thus obtained with the help of two uncontrolled discharge paths are converted back into direct current. The in usual Way in the primary. and secondary DC circuit; switched reactors are coupled with one another in such a way that the direct currents flowing through the throttle coils cause opposing, mutually canceling magnetizations in them.
Gegenstand der vorliegenden Erfindung ist eine Weiterbildung obiger Erfindung, und zwar wird erfindungsgemäß jede Phasenwicklung des Wechselstromkreises über Paare gegensinnig parallel geschalteter, gesteuierter Entladungsgefäße an das primäre bzw. sekundäre Gleichstromnetz angeschlossen. Es ist bereits ,an.anderer Stelle darauf hingewiesen worden, daß sich durch die Anwendumg von Paaren gegensinnig parallel geschalteter Entladungsgefäße bei Umformungseinrichtungen verschiedene Vorteile :ergeben. So lassen, sieh z. B. die Blindleistungsverhältnisse besser beherrschen. Es wird bemerkt, daß, die Frage der Blindleistungsverhältnisse eine besondere Rolle spielt, wenn der Wechselstromkreis entsprechend belastet wird. Ferner ist auch beim Energierichtungswechsel kein Umpolen der Gleichstromzuleitung notwendig. In der Zeichnung ist ein Ausführungsbeispiel .der Erfindung .dargestellt. Dem Gleichstromnetz i sind die Paare gegensinnig parallel geschalteter Entladungsgefäße i i', I I" und 12', 12", dem Gleichstromnetz 3 tdie Paare 31' , 31" und 32', 32" zugeordnet. Die Anordnung enthält ferner die Komrnutierungskondensatoren 14 und 34 und die @entsprechend den Anordnungen des Hauptpatents geschalteten Drosseln 13 und 33. Grundsätzlich. kann man an Stelle von Paaren gegensinnig parallel geschalteter Entladungsgefäße mit eindeutiger Durchlaßrichtung auch Entladungsgefäße mit zwei iemitti@erenden Hauptelektröden verwenden. Es hat sich aber bei den. Un-, tersuchungen ergeben, daß die Trennung der Entladungswege für Gleichrichter- und Wechselrichterbetrieb eine Vereinfachung der Steuerungsmaßnahmen @ermöglicht. In der Zeichnung ist .angenommen, daß. der Wechselstromzwisc!henkreis, nur einphasig ist. Es wird aber bemerkt, d;aß .unter Umständen ein mehrphasiger Betrieb trotz der erhöhten Anzahl von Entladungsgefäßen günstiger sein kann.The subject of the present invention is a further development of the above Invention, according to the invention, each phase winding of the alternating current circuit via pairs of controlled discharge vessels connected in parallel in opposite directions to the primary or secondary direct current network connected. It is already, to another It has been pointed out in my place that by using pairs, one another is opposite to one another Discharge vessels connected in parallel in transforming devices are different Advantages: surrender. So leave, see z. B. master the reactive power ratios better. It is noted that the question of the reactive power ratios plays a special role plays when the AC circuit is loaded accordingly. Furthermore is also with Change of energy direction no need to reverse the polarity of the direct current supply line. In the The drawing shows an exemplary embodiment of the invention. The direct current network i are the pairs of discharge vessels connected in parallel in opposite directions i i ', I I "and 12 ', 12 ", the direct current network 3 t the pairs 31', 31" and 32 ', 32 "assigned The arrangement also includes the communication capacitors 14 and 34 and the corresponding the arrangements of the main patent switched chokes 13 and 33. Basically. can be used instead of pairs of discharge vessels connected in parallel in opposite directions with a clear direction of passage also discharge vessels with two emitting ends Use main electrodes. But the. Investigations result that the separation of the discharge paths for rectifier and inverter operation a simplification of the control measures @ enables. In the drawing it is assumed that. the AC intermediate circuit is only single-phase. It is noted, however, that ate .possibly a multi-phase operation despite the increased number of discharge vessels can be cheaper.
Die Wirkungsweise von Anordnungen gemäß der vorliegenden Erfindung ist im wesentlichen dieselbe wie bei den im Patent 436 825 beschriebenen Anordnungen.The operation of arrangements according to the present invention is essentially the same as the arrangements described in patent 436,825.
