Abstract

A highly linear photon-coupled isolation unit has been developed, so that output ramps of various slopes and step changes are reproduced with little error to be employed as stimuli. The design uses matched photocouplers where one is in a feedback configuration. The analysis, characteristics and method of measuring the isolation parameters are discussed.

Sommaire

On a mis au point un isolateur à accouplement de photons à forte linéarité afin de reproduire avec une marge d'erreur réduite les rampes de sortie de diverses pentes et changements d'échelons, ces produits devant être utilisés comme simulants. Pour cela, on a fait appel à des photo-coupleurs apariés dont l'un est en configuration de réaction. L'auteur examine l'analyse, les caractéristiques et la méthode de mesure des paramètres d'isolement.

Zusammenfassung

Ein hochgradic linearer, photongekoppelter Isolator wurde entwickelt, um Ausgangs sägezahnschwingungen verschiedener Steilheit und sprunghafte Änderungen, die als Reizgeber verwendet werden, mit nur geringfügiger Regelabweichung wiederzugeben. Bei dieser Konstruktion werden passende Fotokoppler verwendet, von denen einer eine rückgekoppelte Ausführung ist. Analyse, Eigenschaften und Meßverfahren für die Isolierparameter werden besprochen.
