A magnetic structure for wireless power transfer has a plurality of pieces of magnetically permeable material arranged along a first dimension. Each piece is separated from a neighbouring piece by a gap defining a separation distance which is selected to prevent partial saturation of a region of the structure.

Current distribution and thermal regulation in inductive power transfer coupling structures

A method of detecting a wirelessly powered vehicle on a roadway uses detection of induced voltages or currents in coils provided in the roadway. Once the vehicle has been detected the appropriate coils can be energised to power the vehicle.

Electric vehicle detection for roadway wireless power transfer

Techniques for wirelessly transferring energy to a vehicle are disclosed. An example method for wirelessly transferring energy to a vehicle according to the disclosure includes detecting a ripple frequency on a transmitter coil circuit, such that the ripple frequency is associated with a vehicle switch mode controller frequency of a switch mode controller in the vehicle, and providing an electrical current to a coil in the transmitter coil circuit based at least in part on the ripple frequency.
