WIRELESS ELECTRICITY TRANSMISSION DEVICE AND WIRELESS POWER TRANSMISSION SYSTEM

Title:

WIRELESS ELECTRICITY TRANSMISSION DEVICE AND WIRELESS POWER TRANSMISSION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2015/015690

Kind Code:

A1

Abstract:

This wireless electricity transmission device is provided with: a self-excited oscillation circuit; a detection circuit that detects the output voltage of the oscillation circuit and/or the oscillation frequency of the oscillation circuit; and a control circuit that, on the basis of the detection results of the detection circuit and a detection resonator that outputs the energy output by the oscillation circuit in order to detect the position of an electricity reception device, detects the degree of propinquity of the electricity reception device to the detection resonator.
