Title:

非接触電力伝送機器

Document Type and Number:

Japanese Patent JP5857966

Kind Code:

B2

Abstract:

Provided is a non-contact power transmission apparatus that can be made thinner without any drop in power transmission efficiency. The non-contact power transmission apparatus includes: primary coil (2) generating a magnetic flux (Φ1); secondary coil (4) disposed facing primary coil (2) to receive power in a non-contact manner from primary coil (2) by electromagnetic induction; magnetic-substance layer (5) that covers a side opposite the side of secondary coil (4) facing primary coil (2) so that the magnetic flux (Φ1) can pass; magnet portion (7) disposed to be able to switch two magnetic poles and configured to generate a magnetic flux (Φ2) that is larger than the difference between the maximum value of the first magnetic flux (Φ1) and the saturated magnetic flux of magnetic-substance layer (5) and that passes through magnetic-substance layer (5) in a direction in which magnetic-substance layer (5) spreads; and magnetic pole switching unit (8) that detects the direction of the first magnetic flux (Φ1), and switches the magnetic pole of magnet portion (7) to generate a magnetic flux (Φ2) in a direction opposite the direction of the first magnetic flux (Φ1).
