Description

Es sind Anordnungen bekannt. die unter Zuhilfenahme. gesteuerter Gas- oder Dampfentladungsstrecken Gleichstrom in Wechselstrom umformen. Solche bisher bekanntgewordenen Wec1iselrichterschaltungen liefern eine von der Eingangsspannung und den Schaltungskonstanten abhängige, im übrigen der Amplitude nach konstante Wechselspannung.' -Nach derErfndung wird ein;: derAmplitude nach veränderliche Wechselrichterausgangsspannung dadurch gewonnen, daß mehrere Wechselrichter, von denen einer selbstgeführt ist und die Steuerspannungen der anderen Wechselrichter bestimmt, über phasendrehende Mittel miteinander verbunden und ausgangsseitig in Reihe geschaltet sind. Die Erfindung ermöglicht auf diese Weise grundsätzlich eine Spaimungsamplitudenänderung, wie sie mit den bisher bekanntgewordenen, Wechselrichteratiordnungen nicht durchführbar ist.Arrangements are known. the with the help. controlled gas or vapor discharge paths convert direct current into alternating current. Such so far Inverter circuits that have become known supply one of the input voltage and the circuit constants dependent, otherwise the amplitude constant AC voltage. ' -According to the invention, the inverter output voltage is variable according to the amplitude obtained by having several inverters, one of which is self-guided and the control voltages of the other inverters are determined via phase-rotating Means are connected to one another and connected in series on the output side. The invention in this way basically enables a change in the relaxation amplitude, as she does not feasible with the previously known inverter regulations is.

Das in der Zeichnung veranschaulichte Ausführungsbeispiel besteht aus einem selbstg2steuerteiz und einem von diesem fremdgesteuerten Wechselrichter. Die Kathoden der beiden gitterg; steuerten Röhren des selbsterr;gten W@cliselrichters I sind miteinander sowie über den Gi tterableitungskreis k und die Gitterwiderstände R.r mit den Rö1irengittern v=erbunden. Anodenseitig sind die Röhren durch den Löschkond; nsator K und den Steuerzweig R, h.- überbrückt. Die Selbststenerung erfolgt durch indulztive übertragung der erzeugten Wechselspannung auf die Gltterkr@ise. Als Phasenschieber für die vom selbsterregten Wechselrichter erzeugte und dem Wechselrichter II als Steuerspannung über den Gittertransformator T, zugeführte Spannung dient hier ein veränderliches RL- , Glied mit einer durch Gleichstromvormagnetisierung veränderlichen Selbstinduktion, wobei der '#-ormagnetisi:rtingsstrom der gegebenen und umzuformenden Gleichspannung .über eine Drossel D,. und den Spannungsleiter P entnommen wird. Die Phasenverschiebung kann auch auf irgendeine andere Weise vorgenommen werden, z. B. durch ein in der Zeichnung nicht dargestelltes RC-Glied. Im iibrigz#n unterscheidet sich der Aufbau des Wechselrichters II von dem des Wechselricht; rs I nur durch den .Fortfall des Steuerzweiges RS IL.5.The embodiment illustrated in the drawing consists from a self-controlled unit and an externally controlled inverter. The cathodes of the two latticed; controlled tubes of the self-made judge I are with each other as well as via the Gi tter derivative circuit k and the grid resistances R.r tied with the pipe grids. On the anode side are the tubes through the quenching condenser; nsator K and the control branch R, i.e. bridged. The self-control takes place through Indulatory transfer of the generated alternating voltage to the smoothing circuit. As a phase shifter for the generated by the self-excited inverter and the inverter II as Control voltage via the grid transformer T, supplied voltage is used here Variable RL-, element with a variable by direct current bias Self-induction, where the '# -ormagnetization: rtingsstrom is given and to be transformed DC voltage. Via a choke D ,. and the voltage conductor P is removed. The phase shift can also be done in some other way, z. B. by an RC element not shown in the drawing. In the iibrigz # n differentiates the structure of the inverter II differs from that of the inverter; rs i just through the discontinuation of the RS IL.5 control branch.

Eine selbsttätige Spannungsregelung kann dadurch erreicht werden, daß die Phasenverschiebung zwischen den beiden N\'echselrichterspannungen in Abhängigkeit von Ausgangsspannung. Ausgangsstrom oder Ausgangsleistung geregelt wird.Automatic voltage regulation can be achieved by that the phase shift between the two N \ 'converter voltages as a function of of output voltage. Output current or output power is regulated.
