Regelbare Gleichspannungsversorgung für den Betrieb von GasentladungsstrahlernAdjustable DC voltage supply for the operation of gas discharge lamps

Gasentladungsstrahler, wie beispielsweise Quecksilberdampfstrahler, sind im Gegensatz zu üblichen Stromverbrauchern durch eine Strom-Spannungskennlinie gekennzeichnet, die je nach Strahlerstrom und Strahlerart sowohl positive als auch negative Steigung annehmen kann. Für ihren Betrieb sind also besondere Spannungsquellen erforderlich, die den negativen Strom-Spannungskennlinien Rechnung tragen. Als Spannungsquellen für solche Strahler sind Vorschaltspulen, Streufeldtransformatoren, Transduktoren und Thyristorsteller mit nachgeschalteten Transformatoren bekannt. Diese Stromversorgungen sind aufwendig an verschiedene Strahlerleistungen anzupassen und können nur in geringem Umfang veränderten Netzverhältnissen Rechnung tragen. Sie haben außerdem hohe elektrische Verluste, hohes Gewicht und großen Platzbedarf.Gas discharge lamps, such as mercury vapor lamps, In contrast to common electricity consumers, they are characterized by a current-voltage characteristic, which, depending on the lamp current and type, can have a positive as well as a negative slope. For their operation, special voltage sources are required that correspond to the negative current-voltage characteristics Take into account. The voltage sources for such radiators are ballast coils, stray field transformers and transducers and thyristor controllers with downstream transformers are known. These power supplies are expensive adapt to different emitter powers and can only change network conditions to a small extent Take into account. They also have high electrical losses, a high weight and a large space requirement.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt demnach die Aufgabe zugrunde, eine regelbare Spannungsversorgung für Gasentladungsstrahler zu schaffen, die verlustarm arbeitet, Netzschwankungen ausregeln kann, modular aufgebaut und einfach an wechselnde Strahlertypen angepaßt werden kann.The invention aims to provide a remedy here. The invention is therefore based on the object of a controllable voltage supply to create for gas discharge lamps that works with low loss, can regulate network fluctuations, modular structure and can be easily adapted to changing heater types.

Die Aufgabe wird dadurch gelöst, daß die Spannungsversorgung aus einer oder mehreren ungeregelten Spannungsquellen und einer mit diesen in Reihe geschalteten veränderlichen Spannungsquelle besteht.The object is achieved in that the voltage supply consists of one or more unregulated voltage sources and a variable voltage source connected in series with them.

In einer Ausgestaltung kann die veränderliche Spannungsquelle stufenlos durch Veränderung ihrer Amplitude oder Veränderung ihrer Einschaltdauer (Taktung) regelbar sein.In one embodiment, the variable voltage source can be steplessly changed by changing its amplitude or Change in their duty cycle (clocking) can be regulated.

Die Erfindung wird anhand der Figuren näher erläutert. Es zeigt:The invention is explained in more detail with reference to the figures. It shows:

Die starre (unregelbare) Gleichspannungsquelle U ist mit der veränderbaren (regelbaren) Gleichspannungsquelle U in Reihe geschaltet. Parallel zu U ist eine Freilaufdiode D angeordnet, über die der Strahlerstrom bei U=O fließt. S symbolisiert den Strahler und Z eine Vorsehaltimpedanz (Induktivität). Für eine stufenlose Regelung eignet sich die aus Figur 2 ersichtliche Spannungsquelle Up, bestehend z.B. aus den drei Phasen L-,, L2, Lo eines Drehstromnetzes und der Brückenschaltung aus denThe rigid (uncontrollable) direct voltage source U is connected in series with the variable (controllable) direct voltage source U. A free-wheeling diode D is arranged parallel to U, through which the radiator current flows when U = O. S symbolizes the radiator and Z a reserve impedance (inductance). The voltage source Up shown in FIG. 2 , consisting, for example, of the three phases L 1 , L 2, Lo of a three-phase network and the bridge circuit from the, is suitable for stepless regulation
