11. A non-contact power transfer device comprising:
-
a power transmitter configured to transmit power to a power receiver in a non-contact manner; a foreign object detection device configured to detect a foreign object located on or near a power transfer path from the power transmitter to the power receiver; and a power controller configured to control the power transmitted from the power transmitter, depending on whether a foreign object is detected by the foreign object detection device, wherein the foreign object detection device comprises; a foreign object detector configured to detect the foreign object, the foreign object detector being arranged between the power receiver and the power transmitter; and a power control signal generator configured to generate a power control signal which controls the power transmitted from the power transmitter when the foreign object is detected by the foreign object detector. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
