INTEGRATION OF SOLENOID POSITIONING ANTENNAS IN WIRELESS INDUCTIVE CHARGING POWER APPLICATIONS

摘要

An apparatus for determining a position between a wireless power transmitter and a wireless power receiver is provided. The apparatus comprises a ferrite structure. The apparatus further comprises a plurality of detection loops formed from metallic traces on a flexible printed circuit wrapped on or around the ferrite structure. Each of the plurality of detection loops comprises a solenoid detection loop. The ferrite structure comprises a first ferrite block and a second ferrite block disposed adjacent to the first ferrite block. A first wireless power transfer coil is wrapped on or around the first ferrite block. A second wireless power transfer coil is wrapped on or around the second ferrite block. Each detection loop of the plurality of detection loops is configured to sense an amount of magnetic flux flowing in a direction normal to a winding plane of the detection loop.
