Abstract

L'invention concerne selon un premier aspect un coupleur puissance/données (20, 30) destiné à être relié à une ligne électrique (3) mutualisée pour la transmission de puissance en basse fréquence et la transmission d'un signal numérique de données en haute fréquence, comprenant un circuit magnétique (5, 15) dans lequel en utilisation la puissance génère un flux magnétique dans la partie basse du spectre et le signal numérique génère un flux magnétique dans la partie haute du spectre, caractérisé en ce qu'il comporte des moyens (8-13, 21-25) pour générer dans le circuit magnétique un flux magnétique de basse fréquence, dit flux démagnétisant, de sens opposé au flux magnétique généré par la puissance.
