Title:
WIRELESS POWER SUPPLY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/128554
Kind Code:
A1
Abstract:
This wireless power supply apparatus is provided with: a first wire wound section (15); a second wire wound section (18), which is disposed at an interval between the first wire wound section and the second wire wound section, said second wire wound section being in the direction of the axis (17) of the first wire wound section; and a pair of magnetic material members (23, 14), which are disposed to sandwich the first wire wound section and the second wire wound section from the axis direction. The magnetic material member (23) is provided with protruding sections (22a, 22b), which protrude toward the other magnetic material member (14), and the magnetic material member (23) is held such that the magnetic material member can move forward to and backward from the other magnetic material member (14). Consequently, since a magnetic coupling coefficient between transmitting and receiving sections during charging is improved, charging efficiency can be improved.
