Abstract
An inductive power transmitter 2 comprising: a plurality of transmitter coils 7; a controller 8 configured to selectively energise the coils 7 in order to couple a receiver 3, the coils 7 selected being dependent on an orientation of the receiver 3, a power transfer optimisation algorithm, or a lookup table.
Claims13
An inductive power transmitter comprising:
- a plurality of transmitter coils;
- and
- a controller configured to selectively energize one or more transmitter coils of the plurality of transmitter coils to transmit wireless power to a receiver, the one or more transmitter coils selected being dependent on an orientation of the receiver,
- wherein the one or more transmitter coils are arranged into a planar array, wherein the one or more transmitter coils are selected in order to generate a flux, wherein a substantial component of the flux couples to the receiver, and wherein the substantial component is substantially perpendicular to the receiver.
