Title:
POWER-TRANSMITTING DEVICE AND POWER-FEEDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/087399
Kind Code:
A1
Abstract:
By appropriately controlling the transmission or interruption of power from a power-transmitting device to a power-receiving device, this invention solves the problem of a power-transmitting circuit being damaged by an increase in the amount of current supplied thereto. This power-transmitting device contains the following: a power-transmitting circuit that has a power-transmitting coil (24) for supplying power to a power-receiving coil (34) in a power-receiving device; a magnetic body (26) that is magnetically coupled to the power-transmitting coil (24); and a movement device that changes the relative positions of the magnetic body (26) and the power-transmitting coil (24) so as to change the impedance of the power-transmitting circuit such that the aforementioned power is either interrupted or supplied.
