Title:
POWER SUPPLY DEVICE AND POWER RECEIVING DEVICE USED IN CONTACTLESS POWER TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2013/001810
Kind Code:
A1
Abstract:
In the present invention, a power supply device (2) is provided with: a primary coil (12) for generating a magnetic flux from an inputted alternating current; a cover (29) for covering the primary coil (12); and a sheet-shaped thermosensitive sensor (28) for detecting the temperature of an object (30) on the cover (29). This makes it possible to use the sheet-shaped thermosensitive sensor (28) during power transmission to detect a temperature rise on the cover (29) of the power supply device (2) and accurately detect the presence of the object (30) on the cover (29). The use of the sheet-shaped thermosensitive sensor (28) also makes it possible to easily and accurately detect a broad region on the cover (29) where the temperature of a foreign object may rise.
