A loosely coupled inductive power transfer system suitable for transferring power to a mobile conveyer platform or a vehicle has pick-up coils wound on flux concentrator(s). One or more large flat horizontal ferrite cores 607, 608 are used to concentrate the horizontal component of magnetic flux from an extended volume into one or more secondary or pick-up coils 613. Each shock-resistant core comprises an array of many individual strips of ferrite held in close contact. One, more usually two, or perhaps more resonant pick-up windings are wound about each core and each winding has a shorting switch (within 602, 603 . . . ) placed across it. A controller 601 connects a controlled output voltage on to an output bus 605, 606 from the best-placed pick-up winding on any one core at any moment, while holding the others in a shorted hence inactive state.
Inductive power pick-up means comprising a plurality of pick-up coils mounted on a movable support, said coils being spaced apart from one another, each coil being adapted to pick-up inductive power from a primary conductor so that each coil acts as a secondary conductor when located relative to sai
Inductive power pick-up means comprising a plurality of pick-up coils mounted on a movable support, said coils being spaced apart from one another, each coil being adapted to pick-up inductive power from a primary conductor so that each coil acts as a secondary conductor when located relative to said primary conductor, and control means capable of identifying from time to time the pickup coil or coils in best alignment with said primary conductor, said control means including switching means capable of switching “on”the identified pickup coil or coils which are best placed to collect inductive power from said primary conductor, and to render functionally inactive the coil or coils which are remote from said primary conductor.
