Abstract
L'invention améliore nettement un montage redresseur connu pour des signaux de courant alternatif en y adjoignant un circuit 18 qui mesure un déséquilibre de courant continu à la sortie et règle ensuite ce déséquilibre pour l'éliminer en renvoyant des courants de compensation au circuit redresseur 2. Un domaine de mesure dynamique de 1 sur 10.000 ou plus est alors possible. Le montage redresseur 2 fournit un courant dont la forme correspond à celle du signal alternatif d'entrée. Applications : mesures de la valeur efficaces de signaux alternatifs.
