Description
Es ist bekannt, daß als Stetterspannungien für gittergesteuerte Dampf- oder ■Gasentladungsstrecken vorteilhaft Spannungein spitzer Kurvenform, verwendet werden, und es ist ferner bekannt, zur Erzeugung derartiger Kurvenformen eine Reihenschaltung einer ungesättigten Drossel (3 in Abb. 2) mit einem hochgesättigten, die eigentlichen Steuerspannungen liefernden Transformator (4 in Abb. 2) zu benutzen. Die Drossel erzwingt dabei einen sinusförmigen, verlauf des Stromes im Transformatorprimärkreis. Dieser eilt der angelegten Gesamtspannung tun rund 900 nach, und entsprechend sind auch die ausgangsseitig entnommenen spitzen Spannungsimpulse um 90° in der Phase gegen die NuIldurchgünge der angelegten Primärspannung verschoben.It is known that a pointed waveform voltage is advantageously used as Stetter Voltage for grid-controlled vapor or gas discharge paths, and it is also known to connect an unsaturated choke (3 in Fig. 2) in series with a highly saturated choke, the actual one, to generate such waveforms Use the transformer supplying control voltages (4 in Fig. 2). The choke forces a sinusoidal course of the current in the transformer primary circuit. This hastens the applied total voltage do around 90 to 0, and accordingly the output side taken sharp voltage pulses are shifted by 90 ° in phase from the NuIldurchgünge the applied primary voltage.
Soll daher eine derartige spitze Spannung zum Zweck der Regelung auch in der Phase verschiebbar ausgebildet werden, z. B. in einer der bekannten Brücken- oder Spannungsteilerschaltungen nach Abb. 1, so ergibt sich die Schwierigkeit, daß eine' stetige Steuerung der angeschlossenen Entladungsstrecken nur in einem Teilbereich möglich ist. Wird beispielsweise in der Anordnung der Abb. 1 der veränderliche Widerstand 1 zu Null, so ist die Ausgangsspannung der Spannungsteilerschaltung gleichphasig mit der Eingangsspannung. Speist diese Ausgangsspannung eine Anordnung zur Erzeugung spitzer Spannungen nach Abb. 2,. so treten die Spannungsspitzen infolge des nacheilenden Stromes jeweils im Scheitelwert der Sinusspannung auf. Die gesteuerte Entladungsstrecke wird also erst etwa im Scheitelpunkt der Anodenspannung freigegeben (Abb. 3). Durch Erhöhung des Widerstandes ι bei konstanter Kapazität 2 läßt sich leicht eine Vierschiebung des Zündeinsatzes der Entladungsstrecke zwischen 90 und i8o° erzielen, bezogen auf den Nulldurchgang der Anodenspannung. In dem Bereich zwischen 90 und 0° kann jedoch nur geregelt werden, wenn die Eingangs spannung der Gesamtan-Ordnung umgepolt und dann der Kondensator 2 vergrößert wird. Dies bedingt jedoch einen besonderen Umschalter, also erhöhten Aufwand; außerdem kann auf diese Weise keine wirklich stetige Regelung der Entladungsstrecke über die ganze Halbwelle hinweg erzielt werden.Should therefore such a peak voltage for the purpose of regulation also in the phase be designed to be displaceable, e.g. B. in one of the known bridge or voltage divider circuits according to Fig. 1, the difficulty arises that a 'continuous control of the connected discharge paths is only possible in a partial area. For example in the arrangement of Fig. 1 the variable resistance 1 to zero, so is the Output voltage of the voltage divider circuit in phase with the input voltage. This output voltage feeds an arrangement for generating acute voltages Fig. 2 ,. so the voltage peaks occur due to the lagging current in each case in the peak value of the sinusoidal voltage. The controlled The discharge path is therefore only released approximately at the apex of the anode voltage (Fig. 3). By increasing the resistance ι at constant capacitance 2 can slightly shifting the ignition insert of the discharge path by four between 90 and 180 ° achieve, based on the zero crossing of the anode voltage. In the area between However, 90 and 0 ° can only be controlled if the input voltage is in the overall arrangement reversed polarity and then the capacitor 2 is increased. However, this requires a special switch, i.e. increased Expenditure; in addition, no really continuous regulation of the discharge path can be achieved in this way can be achieved over the entire half-wave.
