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.
