PLANAR MAGNETIC ELEMENT FOR NON-CONTACT CHARGER |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To remarkably thin a planar magnetic element loaded on a non-contact charger and to improve charging efficiency. <P>SOLUTION: In the planar magnetic element, a spiral planar coil is embedded in one face of a magnetic layer. A magnetic window is given in a center of the planar coil and a part of the magnetic window is composed of a magnetic material whose relative permeability is not less than 100. <P>COPYRIGHT: (C)2004,JPO</p> |
