Abstract

An electromagnetic arrangement comprises a ferrite core (9a). A primary transformer winding (6a) is connected in series with an inductor winding (23a). The primary transformer winding (6a) and the inductor winding (23a) are each wound around part of the main body (13a) of the core (9a). A secondary winding (10a) is attached to a separate ferrite plate (14a). The electromagnetic connector is configured to couple power in an electrical distribution system that operates with a high frequency alternating current.
