Eine auch als Burst-Signal bezeichnete getaktete Wechselspannung wird für Auswertungs- und Meßzwecke üblicherweise in gleichgerichtete Impulspakete umgeformt. Derartige Umformungen mittels Gleichrichterschaltung sind für diverse sehr unterschiedliche Anwendungsfälle gebräuchlich. Als Beispiel sei die Auswertung beziehungsweise Überwachung blinkender Signallampen in Eisenbahn-Stellwerken genannt. Bei den meisten Anwendungsfällen kommt es darauf an, möglichst kurze Ein- und Ausschwingzeiten der Gleichrichtung zu erreichen, um auch höhere Taktfrequenzen und variable Tastverhältnisse präzise meßtechnisch erfassen zu können.A Also called burst signal clocked AC voltage is for evaluation and measuring usually transformed into rectified pulse packets. Such transformations By means of rectifier circuit are for various very different use cases common. An example is the evaluation or monitoring of flashing signal lamps called in railway signal boxes. For most applications comes it is important, if possible achieve short ringing and decay times of the rectification, even higher Clock frequencies and variable duty cycles to be able to capture precise metrology.

Die Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Die Eingangswechselspannung wird in einem positiven und einem negativen Gleichrichterteil getrennt bearbeitet und im nachfolgenden Differenzverstärker zur Vollwellengleichrichtung zusammengesetzt. Danach wird in einem Spitzenwertgleichrichter die pulsierende Gleichspannung mittels Ladekondensator gespeichert und über einen Bufferverstärker zur Messung bereitgestellt. Vom positiven und vom negativen Gleichrichterteil wird je ein Steuersignal abgeleitet und in einer einfachen Logikschaltung so aufbereitet, dass mit dem letzten Nulldurchgang der Eingangswechselspannung der Ladekondensator sehr rasch entladen wird.The The object is achieved with the characterizing features of claim 1. The AC input voltage is in a positive and a negative Rectifier part processed separately and in the following differential amplifier for Full wave rectification composed. After that, in a peak rectifier the pulsating DC voltage stored by means of a charging capacitor and over a buffer amplifier provided for measurement. From the positive and the negative rectifier part is ever derived a control signal and in a simple logic circuit prepared so that with the last zero crossing of the input AC voltage the charging capacitor is discharged very quickly.
Durch diese Schaltung werden gegenüber der oben beschriebenen bekannten Schaltung sowohl eine verbesserte Glättung der Eingangswechselspannung als auch kürzerer Ein- und Ausschwingzeiten erreicht.By this circuit will be opposite the The known circuit described above both improved smoothing of the Input AC voltage as well as shorter settling and decay times reached.
