Abstract

L'invention concerne un système (1) de transfert sans contact d'énergie électrique entre une source de courant (2) et un consommateur (4). Dans ce système (1), deux transformateurs (11, 21) pourvus chacun d'un convertisseur (15, 25), sont couplés sans contact à un conducteur (31) se présentant sous forme de boucle sans fin. Un (11) des transformateurs est un transformateur d'alimentation en énergie électrique et l'autre (21) est un transformateur capteur d'énergie électrique. Cette configuration permet de prélever sur le conducteur (31), de manière aisée sur une longue distance, de l'énergie électrique de puissance élevée et de la mettre à la disposition d'un ou de plusieurs consommateur(s) (4). L'alimentation comme le prélèvement de l'énergie électrique s'effectuent sans contact et les déperditions mécaniques et électriques sont de ce fait réduites.
