摘要： A feeding coil circuit 120 feeds power by wireless from a feeding coil L2 to a receiving coil L3 based on a magnetic field resonance phenomenon between the feeding coil L2 and receiving coil L3. A transmission power control circuit 200 supplies AC power at a drive frequency to the feeding coil L2 to make the feeding coil L2 feed the AC power to the receiving coil L3. A phase detection circuit 114 measures a phase difference between a current phase of the AC power and a voltage phase thereof. The power transmission control circuit 200 adjusts the drive frequency in accordance with the phase difference. A protection circuit 122 adjusts the phase difference in an increasing direction when the current flowing in the feeding coil L2 increases.
