DETECTING DEVICE, POWER SUPPLY SYSTEM, AND DETECTING DEVICE CONTROL METHOD |
| 摘要 |
A detecting device includes: a measurement coil made up of a first partial coil to which current in a particular direction is induced by a magnetic field to be supplied to a power reception coil configured to receive power, and a second partial coil to which the current in the opposite direction of the particular direction is induced by the magnetic field; a measurement unit configured to measure the voltage of the measurement coil as measurement coil voltage; and a foreign object detecting unit configured to detect a foreign object within the magnetic field based on the measurement coil voltage. |
