Abstract

La présente invention se rapporte à un agencement électromagnétique qui comprend un noyau ferritique (9a). Un enroulement de transformateur primaire (6a) est raccordé en série à un enroulement d'inducteur (23a). L'enroulement de transformateur primaire (6a) et l'enroulement d'inducteur (23a) sont chacun enroulés autour d'une partie du corps principal (13a) du noyau (9a). Un enroulement secondaire (10a) est fixé à une plaque de ferrite distincte (14a). Le connecteur électromagnétique est configuré pour coupler un courant dans un système de distribution électrique qui fonctionne avec un courant alternatif à haute fréquence.
