CONTACTLESS POWER SUPPLY DEVICE AND CONTACTLESS POWER SUPPLY SYSTEM PROVIDED THEREWITH, CONTACTLESS POWER SUPPLY METHOD, AND CONTACTLESS POWER SUPPLY PROGRAM

摘要

This contactless power supply device (10), which communicates with a power receiving device (20) and supplies power to the power receiving device (20), is provided with a power supply coil (13), a wireless communication unit (16), and a power supply control unit (15). The power supply coil (13) supplies power to the power receiving device (20). The wireless communication unit (16) communicates with the power receiving device (20). Once reception of data transmitted from the power receiving device (20) has been started in the wireless communication unit (16), if the magnitude of the field intensity contained in the data is less than a prescribed threshold value, then the power supply control unit (15) performs correction to increase the output value of the power supplied from the power supply coil (13) to the power receiving device (20).
