Abstract
Provided is a contactless power supplying system which is efficient and can be built of small coils by appropriately limiting power to be inputted into a transmitting coil. In the contactless power supplying system, power transmitted from a transmitting coil is received by a receiving coil by means of magnetic coupling, and the contactless power supplying system includes a power control unit configured to cause power from a power source to flow through the transmitting coil and a control unit configured to perform power limiting control of limiting the power flowing through the transmitting coil by controlling the power control unit.

6. A contactless power supplying system comprising:
-
a transmitting coil configured to transmit power; a power control unit configured to cause power from a power source to flow through the transmitting coil; a receiving coil configured to receive the power transmitted from the transmitting coil by means of magnetic coupling; a load to which power outputted from the receiving coil is inputted; and a control unit configured to perform power limiting control of limiting the power flowing through the transmitting coil by controlling the power control unit, wherein the control unit selects a control mode to be employed for the power limiting control based on a coil coupling condition between the transmitting coil and the receiving coil and a magnitude relationship between an induced current and a receiving coil current. - View Dependent Claims (7, 8, 9, 10)
