Abstract: By supplying power from the power-supplying resonator to the power-receiving resonator by means of resonance, an electromagnetic space having a relatively low magnetic field strength is formed between the power-supplying resonator and the power-receiving resonator. In so doing, the position where the electromagnetic space is formed is changed by setting the frequency of the AC power supplied from an AC power source to the power-supplying module to an antiphase resonance mode or an inphase resonance mode, and the size of the electromagnetic space is changed by changing the distance between the power-supplying coil and the power-supplying resonator and the distance between the power-receiving resonator and the power-receiving coil.

Abstract: In the present invention, the power consumption of a power-supplying module is reduced in the case (standby state) that the power-supplying module and a power-receiving module are not in a power-suppliable region without providing a new device while suppressing the strength of a magnetic field generated in the vicinity of the power-supplying module and the power-receiving module. The wireless power transmission apparatus is such that the power-supplying module, which supplies power using a resonance phenomenon to the power-receiving module from the power-supplying module connected to an AC power source, is operated at a power source frequency such that the input impedance of the power-supplying module in a standby state in which a magnetic field space is not formed is greater than the input impedance of the power-supplying module and power-receiving module in a power-supplying state in which a magnetic field space is formed.

Abstract: A variable magnetic field in which a power-supplying coil and a power supplying resonator exist is generated only by the power-supplying coil. Power-supplying coils and each of which generates a variable magnetic field due to the supply of a variable current via a first current path on one coil end a side and a second current path on the other coil end side; resonance capacitors which are provided on the first current path and the second current path; and a power-supplying coil short-circuit mechanism which is able to cause at least one of the power-supplying coils and to function as a power supplying resonator by allowing the end portions and of the first current path and the second current path to short-circuit with each other are provided.

Abstract: A wireless power transmission device supplies power by means of a resonance phenomenon, from a power supply module equipped with at least a power-supply resonator to a power-receiving module equipped with at least a power-receiving resonator. For the power-supply resonator and the power-receiving resonator, a value for a transmission characteristic of a power source frequency for power is set so as to have two peak bands, and By setting the power source frequency for the power supplied to the power supply module to the power source frequency band corresponding to one of the two peak bands of the transmission characteristic, magnetic field spaces having a magnetic field strength less than the surrounding magnetic field strength are formed in the area near the power-supply resonator and the power-receiving resonator.
