摘要： Wireless power transfer systems, disclosed, include one or more circuits to facilitate high power transfer at high frequencies. Such wireless power transfer systems include a damping circuit, configured to dampen a wireless power signal such that communications fidelity is upheld at high power. The damping circuit includes at least a damping transistor that is configured to receive, from the transmitter controller, a damping signal for switching the transistor to control damping during transmission of the wireless data signals. Utilizing such systems enables wireless power transfer at high frequency, such as 13.56 MHz, at voltages over 1 Watt, while maintaining fidelity of in-band communications associated with the higher power wireless power signal.

摘要： An electrically conductive material configured having at least one opening of various unlimited geometries extending through its thickness is provided. The opening is designed to modify eddy currents that form within the surface of the material from interaction with magnetic fields that allow for wireless energy transfer therethrough. The opening may be configured as a cut-out, a slit or combination thereof that extends through the thickness of the electrically conductive material. The electrically conductive material is configured with the cut-out and/or slit pattern positioned adjacent to an antenna configured to receive or transmit electrical energy wirelessly through near-field magnetic coupling (NFMC). A magnetic field shielding material, such as a ferrite, may also be positioned adjacent to the antenna. Such magnetic shielding materials may be used to strategically block eddy currents from electrical components and circuitry located within a device.

摘要： The present application relates to an apparatus which comprises a wireless power transfer system. This system comprises features which allow it to transfer more power wirelessly at extended distances than other systems operating in the same frequency range. The system possesses heat dissipation features; these features allow it to operate effectively in elevated-temperature environments, and to transfer power at higher levels and/or greater distances than a typical power-transfer system. The system also might include design features to withstand mechanical shocks, stresses, and impacts for use in a rugged environment. The system can also comprise adaptations to reduce electromagnetic interference, and can comprise specially shaped components with magnetic/ferrimagnetic properties that enhance performance. Other potential features include power conditioning by combining, within one circuit or one board, multiple elements that protect against excessive current, over-voltage, and/or reverse voltage.
