Title:
NON-CONTACT POWER SUPPLY SYSTEM, RELAY DEVICE, AND NON-CONTACT POWER SUPPLY METHOD
Document Type and Number:
WIPO Patent Application WO/2016/079830
Kind Code:
A1
Abstract:
A non-contact power supply system 1 includes: a power transmission device 10 that performs magnetic field resonance type non-contact power supply by having a power transmission coil 111 and a capacitor 112, which constitute a resonance circuit; one or more power reception devices 30 which receive power supply from the power transmission device 10 by having a power reception coil 311 and a capacitor 312, which constitute a resonance circuit; and a relay device 20 that relays power to the power reception devices 30, said power having been transmitted from the power transmission device 10. The relay device 20 is provided with: a plurality of coils 21 that are connected in series by being provided such that the directions of the winding axes thereof are different from each other; and a capacitor 22 that constitutes the resonance circuit by being connected in series to the coils 21. One of the coils 21 of the relay device 20 is provided such that the winding axis thereof is in the direction to the power transmission device 10, and at least one of other coils is provided such that the winding axis thereof is in the direction to the power reception device 30.
