CONTACTLESS POWER RECEIVING DEVICE, AND CONTACTLESS CHARGING SYSTEM

摘要

A contactless power-receiving device, which is connected to equipment via a connection terminal and which supplies power to the load for the equipment, provided with: a secondary coil which intersects the alternating magnetic flux generated from a primary coil to which an alternating power is supplied; and a control unit which supplies induced electromotive force of the secondary coil to the load. The control unit determines the amount of charge in the load and determines whether or not to supply power to the load on the basis of the determined amount of charge.
