CONTACTLESS POWER SUPPLYING SYSTEM

摘要

The position and orientation of a power receiving coil are estimated based on a presence detection level of each power supplying coil. A power supplying pattern in which an output of the power receiving device becomes maximal is selected for the position and orientation and power is supplied in the power supplying pattern. Accordingly, power can be supplied to the power receiving device with high efficiency regardless of the position and orientation of the power receiving coil.
