NON-CONTACT POWER SUPPLY SYSTEM, POWER TRANSMISSION DEVICE, AND POWER RECEPTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power supply system for efficiently and stably supplying power from a power transmission device to a power reception device, with a simple configuration.SOLUTION: A non-contact power supply system 1 is configured so as to comprise: a power transmission device 10 including a power transmission side resonant circuit (power transmission circuit) configured using power transmission coils 111a, 111b and a capacitor to perform non-contact power supply of a magnetic field resonance system; and a power reception circuit 20 including a power reception side resonant circuit (power reception circuit) configured using power reception coils 211a, 211b and a capacitor to receive power from the power transmission device 10 by the non-contact power supply. The power transmission device 10 includes a plurality of power transmission side resonant circuits constituted by power transmission coils whose winding axis directions are configured so as to be orthogonal to each other; the power reception device 20 includes a plurality of power reception side resonant circuits constituted by power reception coils whose winding axis directions are configured so as to be orthogonal to each other.SELECTED DRAWING: Figure 8
