Abstract
An arrangement place for a device such as a rectifier and a power storage device is easily secured. At the time of power supply using a resonance phenomenon, a power-receiving device generates a magnetic field space having a lower magnetic field strength than other parts at or around the inner side of the power-receiving module, and this magnetic field space is used as the arrangement place of an electronic component. The power-receiving module includes a power-receiving resonance coil which is resonated with a power-supplying module and a power-receiving coil which partly overlaps the power-receiving resonance coil in a coil diameter direction and receives and supplies power from and to the power-receiving resonance coil.
Claims4
A power-receiving/supplying device comprising:
- a coil module configured to receive and supply power from and to another coil module by a resonance phenomenon;
- and
- an electronic component provided in a magnetic field space which is formed by the resonance phenomenon to have a lower magnetic field strength than other parts,
- the coil module including:
- a resonance coil which is resonated with said another coil module;
- and
- a power-receiving/supplying coil which partly overlaps the resonance coil in a coil diameter direction and is configured to receive and supply power from and to the resonance coil.
