A joint resonance frequencies of a transmitter resonance circuit and a relay resonance circuit have a main resonance frequency (MRF). The transmitter is configured to operate at an operational frequency (OPF) from a range of OPFs. The range of OPFs is different than the MRF. The at least one relay comprises a second relay coil connected in series to the first relay coil. One side of the second relay coil faces the device and a second side of the second relay coil is covered by a relay ferrite layer. The second relay coil is smaller than the first relay coil.

摘要： A method of detecting a foreign object presence between a wireless power transmitter and a wireless power receiver, the wireless power transmitter comprising a primary coil for transferring power wirelessly to a secondary coil of the wireless power receiver, comprises: transmitting a calibration ping signal; measuring and recording decay time of the calibration ping signal; transmitting test ping signal; measuring and recording decay time of the test ping signal; and determining the foreign object presence if the decay time of the test ping signal is smaller than decay time of the calibration ping signal and if an absolute value of a difference between them is above a threshold. In addition, or alternatively, a self-frequency of a decaying calibration ping signal is measured and recorded; a self-frequency of a decaying test ping signal is measured and recorded; and the foreign object presence is determined if a difference between the self-frequency of the decaying test ping signal and the self-frequency of the decaying calibration ping signal falls outside a predetermined value.
