Abstract

An object is to provide a power feeding device, a power feeding system, and a power feeding method which are more convenient for a power feeding user at the power receiving end. The power feeding device includes a means of controlling a frequency of a power signal transmitted to a power receiver, based on a proportion of signals, among power signals output to an antenna circuit, that return from the power receiver to the antenna circuit without feeding power to the power receiver.
