Abstract

Circuit de mesure de tension flottante isolée La présente description concerne un circuit de mesure d’une première tension (VIN) comprenant : une première branche (40) reliée entre un premier nœud (48) et un deuxième nœud (30b), la première branche comprenant un premier condensateur en céramique (44), la première tension étant appliquée aux bornes du premier condensateur en céramique ; et une deuxième branche (42) reliée entre le premier nœud (48) et un troisième nœud (30a), la seconde branche comprenant un deuxième condensateur en céramique (46), identique au premier condensateur en céramique, une deuxième tension (VSNS) étant appliquée aux bornes du deuxième condensateur en céramique, le circuit étant configuré pour modifier la valeur de la deuxième tension jusqu’à ce qu’un premier courant traversant le deuxième nœud soit sensiblement égal à un deuxième courant traversant le troisième nœud. Figure pour l’abrégé : Fig. 3
