Document Type and Number:
WIPO Patent Application WO/2013/114576
Kind Code:
A1
Abstract:
In the present invention, a power transmission device comprises a power supply circuit and a power reception circuit, a first coil that is connected by a cable to the power supply circuit and the power reception circuit, a plurality of resonance coils having mutually different diameters and selectively coupled to the first coil using an electromagnetic conductor, and a position control device for controlling the positions of the plurality of resonant coils. The position control device causes the axial direction of one resonant coil from among the plurality of resonant coils to selectively match the axial direction of the first coil.
