摘要：
A power-receiving-side control circuit of a power reception device performs intermittent load modulation by causing an NMOS transistor to be turned ON/OFF during normal power transmission. A power-transmission-side control circuit included in a power transmission control device of a power transmission device monitors, an intermittent change in the load of the power reception device during normal power transmission. The power-transmission-side control circuit determines that a foreign object has been inserted between a primary coil and a secondary coil and stops power transmission when an intermittent change in load cannot be detected. The amount of power supplied to the load may be compulsorily reduced when the load state of the load is heavy.
