Abstract: A power transmitting apparatus including a power supply to generate AC power; a power transmitting inductor to transfer the AC power to a power receiving apparatus through magnetic coupling with a power receiving inductor in the power receiving apparatus; a mutual coupling adjusting unit to adjust a relative position between the power transmitting inductor and the power receiving inductor; and a control unit to control the mutual coupling adjusting unit based on a mutual coupling coefficient between the power transmitting inductor and the power receiving inductor. The control unit controls the mutual coupling adjusting unit so that the mutual coupling coefficient falls within a predetermined range and an upper limit of the predetermined range is a value less than a maximum of the mutual coupling coefficient between the power transmitting inductor and the power receiving inductor.

Abstract: An electric power transmission device as an aspect of the present invention includes a plurality of power transmitters configured to respectively generate magnetic fields. Phases of the respective magnetic fields are set such that the respective magnetic fields cancel out each other. The power transmitters sequentially shift frequencies of the respective magnetic fields to the same value at the same timing. A shift width of each of the frequencies for one-time shifting is limited by an upper limit value.

Abstract: According to one embodiment, a mobile machine includes a mobile body and a plurality of power transmission resonators. The mobile body is capable of being tilted in a particular direction such that a distance between a particular part opposed to a travel surface and the travel surface is reduced. The plurality of power transmission resonators are arranged at portions of the particular part of the mobile body, heights of the portions with reference to the travel surface being approximately identical with each other in a state of the mobile body being tilted.
