Abstract

Die beschriebene Stromquellenschaltung zeichnet sich dadurch aus, das die Stromquellenschaltung eine Steuervorrichtung (T2', T11', T12', T6, IQ1, IQ2) enthält, welche eine die Größe des von der Stromquellenschaltung abgegebenen Stromes bestimmende Komponente (T2) der Stromquellenschaltung steuert, und dass die Steuerung abhängig von den Verhältnissen erfolgt, die in der von der Stromquellenschaltung mit Strom versorgten Einheit herrschen. Dadurch kann erreicht werden, dass die Stromquellenschaltung ohne Beschränkung der Einsatzmöglichkeiten derselben stets einen konstanten Strom liefert.
