NON-CONTACT POWER SUPPLY DEVICE

WIPO Patent Application WO/2016/016930

A1

This non-contact power supply device is provided with: a power supply-side coil that is provided in a power supply-side device; a high-frequency power supply circuit that applies a high-frequency voltage to the power supply-side coil; a power reception-side coil, which is provided in a power reception-side device that is disposed to face the power supply-side device, and which receives, by means of non-contact power supply, high-frequency power by being electromagnetically coupled to the power supply-side coil; a power reception circuit that supplies power to an electrical load of the power reception-side device by converting the high-frequency power received by the power reception-side coil; and at least one resonance member, which is connected to the power supply-side coil and/or the power reception-side coil, and forms a resonance circuit. The high-frequency power supply circuit uses a frequency deviated from a resonance frequency of the resonance circuit. Consequently, it is made possible to simplify device configuration and circuit configuration by suppressing fluctuation of a reception voltage, and to make a contribution to device cost reduction and installation space reduction.
