Title:
CONTACTLESS POWER-FEEDING SYSTEM, POWER TRANSMISSION DEVICE, AND POWER RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/103351
Kind Code:
A1
Abstract:
Provided is a contactless power-feeding system 1 that efficiently and stably feeds electric power from a power transmission device 10 to a power reception device 20 with use of a simple configuration. The contactless power-feeding system 1 comprises: a power transmission device 10 that has power transmission-side resonance circuits (power transmission circuits 11), each configured using a coil 111 and a capacitor 112, and performs magnetic field resonance-based contactless feeding of electric power; and a power reception device 20 that has power reception-side resonance circuits (power reception circuits 21), each configured using a coil 211 and a capacitor 212, and receives the electric power fed by the power transmission device 10 by means of the contactless feeding of electric power. The power transmission device 10 has a plurality of the power transmission-side resonance circuits, wherein the constituent coils 111 of the multiple power transmission-side resonance circuits are configured such that the winding axis directions of the coils are orthogonal to one another. In addition, the power reception device 20 has a plurality of the power reception-side resonance circuits, wherein the constituent coils 211 of the multiple power reception-side resonance circuits are configured such that the winding axis directions of the coils are orthogonal to one another.
