Abstract:
In a non-contact power feeding system which is formed with a power transmission device having a power transmission-side resonant circuit including a power transmission-side coil and a power reception device having a power reception-side resonant circuit including a power reception-side coil and which can transmit and receive power by a magnetic field resonance method, when the power is transmitted, the power transmission device monitors the amplitude of a current flowing through the power transmission-side coil. Then, when a current amplitude detection value (V mFOD ) falls outside a predetermined normal range, it is determined that a foreign object is present, and thus the power transmission is stopped.

Claim (Index 7):
A non-contact power feeding system which comprises: a power transmission device having a power transmission-side resonant circuit including a power transmission-side coil that transmits power; and a power reception device having a power reception-side resonant circuit including a power reception-side coil that receives the power and which can transmit and receive the power by a magnetic field resonance method,\n wherein the power transmission device includes:\n a power transmission circuit which can supply an alternating current voltage to the power transmission-side resonant circuit; \n a detection circuit which detects an amplitude of a current flowing through the power transmission-side coil; and \n a control circuit which performs power transmission control on the power by controlling the power transmission circuit, and \n when the power is transmitted, the control circuit controls, based on an amplitude detection value of the detection circuit, whether or not continuation of the power transmission is allowed.
