A two-part ferrite core 12 comprises core parts which can slide with respect to one another and are positively held together even when exposing one or more channels formed in one of the said parts. Also disclosed is a coupler with a locating mechanism which resists the movement of a part of the ferrite core with respect to a housing. Alternatively, a coupler housing comprises: a secondary winding on a two-part ferrite core where the secondary winding is retained within channels in the ferrite core, or a secondary winding is carried on a printed circuit board. There is also described a two-part ferrite core arrangement comprising a pair of channels formed along the axial direction of an elongate core. A two-part ferrite core, suitable for use in a transformer, where the cross-sectional area of the magnetic path divided by the length of the magnetic path is greater than 2 mm or where the core-sectional area of the magnetic path divided by the cross-sectional area of the core winding is greater than 1, are also described. Alternatively, there is a coupler or ferrite core comprising two ferrite parts arranged to be moved apart from each other in a transitional or rotational manner so as to expose at least one channel in at least one of the ferrite parts for the insertion of a current carrying wire. The coupler arrangements are intended to be used in inductive power transfer and/or high frequency distribution systems. |
