Abstract
Dispositif de mesure d'un paramètre électrique dans un circuit flottant à une tension de mode commun relativement élevée. Une fonction du paramètre à mesurer est appliquée à la diode électroluminescente D1 d'un premier isolateur optique F1 dont le phototransistor T1 fournit en un point éloigné un signal indépendant de la tension de mode commun. Ce signal amplifié Io est ajouté dans un amplificateur différentiel A1 à un signal de contre-réaction If fourni par un deuxième isolateur optique F2 de même caractéristique que le premier, pour compenser la non-linéarité des composants du premier isolateur. Application particulière à la mesure de fortes intensités de courant sous tension continue à composantes ondulatoires.
