Description

Anordnung für die Speisung von vorzugsweise Gleichstromver- brauchern größerer leietung aus Wechselatromquellen unter Verwendung von tastbaren Stromriohterventilen. Ausscheidung aus L 43 369 Wie bereits vorgeschlagen wurde! können elektrische Verbraucher beliebiger Art, d. h. Ohm'sche, induktive, kepa$itive, solche mit und ohne Gegenspannung und Kombinationen daraus über steu- erbare Halbleiterelemente dadurch gesteuert und geregelt werden, daß die Ein- und Ausschaltzeit, d. h. ihr Tastbetrieb variiert wird. Tastbar sind solche elektronischen Verstärkerelemerite, die von Heue aus ein Ein- oder Ausschelten des Leistungsstromes ermöglichen, wenn ihr gteue"trom entsprechend ein- oder auege- schaltet wird. Tastbar sind ferner Stromriahtervantile, vorznge- geisa auf der Ralbleiterbeais, die ein Lia- und Auseobalten er' ßöslichen x: . *ena der ateuerstroa, In der einen-oder anderen Rfch- tung verändert wird (Traneswitch). Ebenfalls tastbar sind Strom- richterventile, die Sperrspannungen in. beiden Richtungen auf- nehmen können und deren Einschalt ea in der Durchlaßrichtung zu beliebiger Zeit erfolgen kann, die aber durch einen kurzzei- tigen Gegenstromstoß - im allgemeinen einen Kondensator entnom- men - gelöscht werden müssen. Ist die freiwerdezeit solcher Ven- tile sehr niedrig,in der Größenordnung von einigen Mikrosekunden, wie das z. B. bei steuerbaren Siliziumzellen der Fall ist, dann kann die zu installierende Kondensatc-:`-istung sehr klein gehal- ten werden, wenn insbesondere bei iswR,rtiven Verbrauchern Prex- laußventile vorgesehen Werden, auf welche der Verbraucherstrom kominutiert Wird. Der Vorteil solcher tastbaren Anordnungen ist, daß der Strom eines beliebigen Verbrauchers nach Vorgabe eiLaß beliebigen Soll- wertes in einfacher Weise geregelt werden kann, indem eine Zwei- punktregelung in der Weise erfolgt, daß das tastbare Stromrich- terventil bei Unterschreitung eines Stromminimalwertes ein- und bei Überschreitung eines Strowmazimalwertes ausgeschaltet wird. Aufgrund der bei tastbaren elektronischen Stronriehterventilen erreichbaren hohen Schaltfrequenz ergeben sich keine Stabilioie- rwngsprobleme. Der forliegbnden .t@rfixung liegt die Aufgabe wigrunde Schaltung&- anordnungen emzugeben, dig es egiiohen, eima bellebigen Vor- braucher, inebaaondere einen'Gleichstromverbraucher größerer leietung in verschiedenen Quadranten des Strom-Hp»=ungs-Kenn- linienfeldes unter Verwendung von testbaren und nicht tastbaren Stromrichtervontilen zu betreiben, wobei besonderer Wert darauf gelegt wird, den Aufwand an zu installierender Ventilleistung so klein wie möglich zu halten. Demzufolge betrifft die Nrfindung eine ScheltungsanoxdnunS für die Speisung, Steuerung und Regelung von vorzugsweise Gleich- stromverbrauchern gröt?erer Leistung aua Wechselstromquellen un- ter Verwendung von vorzugsweise nicht steuerbaren (Dioden), steu- erbaren (Trioden) und tastbaren (ein- und vorzugsweise durch Kon- densatorstromstoß ausschaltbare Trioden) Btromrichterventilend Sie ist dadurch gekennzeichnet, daß zwecks BinBparung an Strom-- ricbterventilen und; oder Löscheinrichtungen und Blindleiatungs- bedarf Brückenschaltungen mit ungleichem lufbau der Brickenzwelge vorgesehen sind. - . fig. 1 zeigt eine einphasige Brückenschaltung für einen Sinstrorr- richtungebetrieb, FG. 2 zeigt eine Brückenanordnung für einen Vierquedrantenbetrieb und _ . Fig. 3 ebenfalls eine Brückenanordnung für einen Vierquadranten- betrieb, bei der jedoch im Gegensatz zu der Anordnung in Fig. 2 nur ein Transformator erforderlich ist.

Der Motorstrom wird beispielsweise über einen Gleich- .. strorävandler 13 erfnßt und einem Stromregler 45 als Strowistwert zugeführt. dieser Stromregler enthUlt gleichzeitigouch die ZInd- und -T;iscbeinrichtimg für die tastbaren Stromrichtorventile 43a urid 43b, ac@fern diese nicht andereweitig löschbar sind (Transstitcb; Entsprechend der Differenz zwischen - Stromist- und Strowollwert werden die tastbaren Sttomrichterventile 43,9 und 43b vorzugsweise im Sinne einer ZReipunktregelung gezündet und gelöscht.

Mit der Brückenanordnung gemäß Fig. 1 .ist eine Gleicbspannungeen-- derung von 0. bis zum vollen Wert .nüglic&. Der Westbetrieb hat den besonderen Vorteil, daß anstelle ' der unter Uxständen aufwendigen Steuergeräte für die Phaeanverschiebunder. Steuerimpulse ein Ai.n-- Aue-Verstärker für die Steuerung der tastbaren StromrichterventilE verwendet werden tann. Parallel zud Treneformator 31 ist in üb- rigen zur Kompensation der Tnduktivität der Wechseletronquelle etn-Kondensator 32 vorgesehen,: dessen Kapazität um so kleiner , sein kann je höher die Taetfrequena ist.-Diese wiederum ist da- ,rozL abhängig, wie genau der eingetastete Motorstrom geragelt Wird. Eine sinngemäße Abwandlung ist auch bei einer drei- und mebrphanigen Schaltung möglich, wenn in der einen Brockenhälfte .n.chteteuerbare und in der anderen HXückenhälfte tastbare Strom- riehterventile vorgesehen sind, wobei die tastbaren gtronrich- terventile bei entsprechender Aussteuerung auch den freilsufstrom führen können. . an sei noch darauf hingewiesen, daß getastete Stromrichter einah gOnstigeren Leistungsfaktor beben eis durch Anschnitt gesteuerte, weil keine Steuerblindleistung benötigt wird und die Komrautie- .rungeblindleietung mit einest Kondensator 32 kompensiert wird. Um die zu installierende Kondensstork&pezität so klein wie m@glieh zu halten, wird vorgeschlagen, die Stromriohtertrafsformatoren türderartige Schaltungen nit blichet kleiner mr:echluespan- nung ausaufabsrn. . ..In 74. 2, ist eine Anordnung dsfsfellt, die einen. Yierquadran- teibetrieb ernöglicht. Dabei sind swti BAskeeepbaituoWn mit i'@gleichea Aufbau der Brückenzweige antiparallel geschaltet, wobei die beiden jeweils derart aufgebaut sind, daß die Stronrichterventile mit gemeinsamer Kathode 33a .33b bzw. 33a, 33d tastbar und die Stromrichterventile mit ge- meinsamer hnode 42a, 42b bzw. 42c, 42d steuerbar -sind. Natiirlict3 könntenatatt der Ventile mit gemeinsamer Kathode auch die VenR- tile mit gemeinsamer Anode tastbar sein. Nr jede der BrüokeL-- echeltungen ist ein gesonderter, durch einen Kondensator 32a bzw. 32b 4iberbrUckter Transformator 3'1a bsß, 31b vorgesehen. Die tastbaren Stromrichterventile werden sowohl -für die Rege hing des dem Motor 9 zu3aführten Gleichstromes als auch für d.t' Übernahme des Freilaufstromes verwendet. Die inkerinduktivittif: des Gleichstrommotors 9 ist nicht gesondert dargestellt, mute aber in Falle-einer echten Riickorbeit bis auf die Verbraucüer- opNU vorhanden sein. Wird den Anker 9 z.

Der I Al, fließt dann über Stromrichterventil 33a, Anker 9 und. )trom-- riohterventil 42b wieder zum Transformator 31a. Der F'reilaui-- atron fließt bei der ange3ebenen Polarität über die ßtrontricha terventile 35b und 42b, die wahrend dieser HslbIwelle dauernd offen gehalten werden. Während der anderen -itslbwelle (eingektam-- nerte Polarität) übeznimzt des tastbare Stronrichtervent i Z 33b die Stromregelung: Dar Strom. IlTfließt dann also aber strr.,.-- richtexventil 33b, Anker 9 und. Stronrichtezventil 42a wiec'sr zum Transformator 31a. Die Stromrichterventile 33a und 42a werden während dieser Halbwelle für den Freilaufstrom dauernd offen gehalten. Soll die Drehrichtung des Gleichstromotore 9 umgekehrt werden, dann ist eine : tromrichtungsumkehr erforder- lich. Dazu werden, nachdem die linke Brückenschaltung gesperrt ist, die Stromrichterventile 33c und 42c geöffnet, so daß die hnkerinduktivität aufgeladen wird, das bedeutet, daß über den Anker 9 und Über die Ventile 42c und 33c ein ansteigender Strom 1A,3 fließt. Bei löachung des tastbaren Stromriahterven- tilen 33c fließt der Strom IAB tlber die Traüeformatorwieklung 31b und über das tastbare Stromrichterventil 33d gegen die Spannung (gezeichnete Polarität) weiter, Es findet also eine Nutzbremsung-statt. Während der Halbwelle mit umgekehrten Vor- wichen (eingeklammert) wird mit dem Stromrichterventil 33d getastet, während das steuerbare Stromrichterventil 42d und das tastbare Stromrichterventil 33c deuerud offen bleiben. Ist der Motor 9 abgebremst, denn wird die rechte Brückenanordnung in gleicher Leise wie vorher die linke Brückenanordnung ausge- steuert, so daß sich die Drehrichtung des Motors nunmehr um- kehrt, In gleicher Meise Wise die in Fig. 2 dargestellte Anordnung funk- tioniert die in F.ig. 3 dargestellte Anordnung, die im Gegensatü zur Fig. 2 jeCoch mir einen einzigen Transformator besitzt.

The advantage of such tactile arrangements is that the current of any consumer according to specifications, any desired value can be easily controlled by a Zw egg point control takes place in such a way that the tactile current direction valve on and off when the current falls below a minimum value is switched off when a maximum current value is exceeded.

Accordingly, the finding concerns a circuit arrangement for the supply, control and regulation of preferably equal power consumers of greater power from AC power sources and using preferably non-controllable (diodes), controllable detectable (triodes) and palpable (one and preferably by con- Triodes that can be switched off by a capacitor surge) Btromrichterventilend It is characterized by the fact that in order to save electricity ricbterventilen and; or extinguishing devices and blind ventilation requires bridge circuits with an uneven structure of the brickwork are provided. -. fig. 1 shows a single-phase bridge circuit for a Sinstrorr- directional operation, FG. 2 shows a bridge arrangement for four-quantum operation and _ .
