Abstract
A non-contact power transmission apparatus includes a non-contact power reception device, and a non-contact power supply device. The non-contact power supply device includes a power transmission coil, a power transmission circuit configured to transmit electric power by the power transmission coil, and a first control circuit configured to drive the power transmission circuit by using electric power of either a first voltage or a second voltage lower than the first voltage. The non-contact power reception device includes a power reception coil electromagnetically coupled with the power transmission coil, and a load circuit to which the electric power received by the power reception coil is supplied when connected to the power reception coil. The first control circuit carries out an authentication processing and a foreign object detection processing for detecting a foreign object before the load circuit and the power transmission coil are connected in the non-contact power reception device.
