Abstract

See full text

A wireless power feeding system includes a power transmission device and a power reception device. A power transmission circuit in the power transmission device switches high-frequency power supplied to a power transmission coil. When a reset IC in the power reception device detects switching of high-frequency power by the power transmission circuit, the power reception device changes an input impedance seen from the power transmission circuit to the side where a load circuit is disposed on the basis of the content of a signal to be transmitted to the power transmission device. The power transmission device detects the change in the input impedance and obtains the content of the signal.
