| 摘要 |
An apparatus for determining a relative position of a wireless power transmitter from a wireless power receiver is provided. The apparatus comprises a driver circuit configured to generate a first signal and a second signal. At least one of the first signal and the second signal oscillates at two frequencies. The apparatus comprises a first generator coil configured to generate a first alternating magnetic field when driven by the first signal. The first generator coil is also configurable to wirelessly transfer charging power from the wireless power transmitter. The apparatus comprises a second generator coil configured to generate a second alternating magnetic field when driven by the second signal. |
