Abstract

Die Erfindung lehrt eine Schaltungsanordnung zum Erzeugen einer Versorgungsgleichspannung in Abhängigkeit von einer - nicht konstanten Eingangsgleichspannung in drei Spannungsintervallen, wobei im mittleren Spannungsintervall die Versorgungsspannung auf einem konstanten Nennbetrag gehalten und in den beiden anderen Spannungsintervallen zur Aufrechterhaltung von Notfunktionen die Versorgungsspannung um konstante Differenzbeträge reduziert wird, indem mittels einer Diodenanordnung der erste Differenzbetrag, mittels einer ersten Zenerdiodenanordnung die Konstanthaltung und mittels einer zweiten Zenerdiodenanordnung eine Überbrückung der Diodenanordnung realisiert wird. Außerdem wird ein Verfahren zum Erzeugen einer Ausgangsspannung für eine Stromimpulse aufgeprägte Signalgebereinheit beschrieben, das eine derartige Versorgungsspannung über einen Regelkreis zuführt. Zur Durchführung des Verfahrens eignet sich die erfindungsgemäße Schaltungsanordnung besonders gut.

The invention teaches a circuit arrangement for generating a DC supply voltage as a function of a non-constant DC input voltage in three voltage intervals, the supply voltage being kept at a constant nominal amount in the middle voltage interval and the supply voltage being reduced by constant difference amounts in the other two voltage intervals in order to maintain emergency functions. in that the first difference is realized by means of a diode arrangement, the constant is maintained by means of a first Zener diode arrangement, and the diode arrangement is bridged by means of a second Zener diode arrangement. In addition, a method for generating an output voltage for a signal generator unit impressed by a current pulse is described, which supplies such a supply voltage via a control circuit. The circuit arrangement according to the invention is particularly suitable for carrying out the method.
