摘要： A measured value of an output voltage may be obtained by rectifying power received through a resonance circuit including a reception coil that receives power from a transmission coil of a power transmission device and a resonance capacitor connected in series with the reception coil. When the measured value becomes equal to or larger than an upper limit threshold value, a power reception device of a non-contact power supply device short-circuits a resonance suppression coil provided so as to be electromagnetically couplable with the reception coil. The power transmission device and the power reception device are provided such that power is transmitted from the transmission coil to the reception coil, and the reception coil and the resonance suppression coil are provided such that a coupling degree between the resonance suppression coil and the transmission coil becomes higher than a coupling degree between the reception coil and the transmission coil.
