摘要： A system for wirelessly charging, via a medium, a device having a receiver coil comprises at least one relay configured to inductively transfer power to the receiver coil of the device and a transmitter configured to inductively transmit, to the at least one relay, power for charging the device. 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 transmitter may inductively transfer power to a device via a relay. The transmitter may comprise circuitry configured to measure a current or voltage and reconfigure the transmitter with an operating frequency or duty cycle based on a measured change in the current or voltage within a time period. The measured change in the current or voltage within the time period may be caused by a removal of the device or an addition of a new device. The time period may be 200 usec or less.

摘要： Aspects of the present invention relates to providing devices, a system and method for controlling wireless power transfer across an inductive power coupling. The system, particularly, relates to enabling selection of a wireless power outlet of a multi-outlet power transmission surface closest to the location of a power receiver connected to an electric load and placed upon the surface. Accordingly, the multi-outlet power transmission surface comprising two sub-systems, a power transmission system and a signal transfer system, each operable independently and continuously. Further, the signal transfer system controls the activation of wireless power, configured to analyze the signal-quality of each detected communication signal received from a power receiver and thereby to identify the wireless power outlet closest to the location of the power receiver.
