Power supplier and receiver and mobile device |
摘要 |
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. |

1. 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 low magnetic field strength, the coil module including: a resonance coil which is resonated with said another coil module; anda 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, the magnetic field space being formed at a predetermined position between or around said another coil module and the coil module to have a lower magnetic field strength than a magnetic field in parts around the predetermined position, by causing a magnetic field generated around the coil module and a magnetic field generated around said another coil module to cancel each other out. |
