<p><P>PROBLEM TO BE SOLVED: To provide a noncontact power transmission device which reduces magnetic flux leaks and makes power transmission more efficient when flat coils are employed as a primary coil and secondary coils. <P>SOLUTION: The noncontact power transmission device has the primary coil 1 and the secondary coils 2, which are physically separable from each other, and transmits electric power without any physical contact, utilizing electromagnetic induction induced between both coils 1, 2. The first coil 1 consist of a flat coil 11, and the secondary coils 2 consist of flat coils 21, 22. When the power transmission device is used, the flat coils 21, 22 are so arranged as to sandwich both faces of the flat coil 11 in between. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
