Patent
Wireless power supply system and wireless power supply method
TL;DR: In this article, a wireless power supply apparatus includes a transmitting coil configured to transmit power in the form of magnetic field energy using magnetic resonance; and a power transmitter configured to supply power at a resonant frequency that produces magnetic resonance between the transmitting coil and a receiving coil.
Patent
Wireless power apparatus and wireless power-receiving method
TL;DR: In this paper, a wireless power apparatus includes a power receiver coil which receives power, as magnetic field energy, from a power transmitter coil by magnetic field resonance produced between the power transmitter coils and the power receiver coils.
Patent
Wireless power supply system
TL;DR: In this article, a wireless power supply system with a power sending resonance coil, a power receiving resonance coil and a relay resonance coil is described, which transmits power wirelessly with a magnetic field resonance mode generated by synchronization of the resonance frequency.
Patent
Power transmission apparatus
TL;DR: A power transmission apparatus includes a cover part attached to one of a power transmitter and an electronic apparatus, the power transmitter including a primary-side coil connected to an alternating-current power supply, and a secondary-side resonant coil configured to receive power from the primary side coil by electromagnetic induction as discussed by the authors.
Patent
Resonance frequency control method, power transmission device, and power reception device for magnetic-resonant-coupling type power transmission system
TL;DR: In this article, the phase difference between the phase of the voltage of the AC power supply and the current flowing through the power-transmission resonance coil is controlled to become a target value.
