摘 要：

<P>PROBLEM TO BE SOLVED: To provide a power transmission device

which can perform efficient energy power feeding, and is simple in constitution, in the power transmission device which

feeds power to an electronic apparatus in a non-contact manner.

<P>SOLUTION: A charging device 1 which is a power transmission device comprises: a primary coil 5 which can be magnetically coupled to a secondary coil 7 arranged at a camera 6; an AC-DC

conversion circuit which feeds a current to the primary coil 5; a voltage detection part which detects an induction voltage at the primary coil side which is generated

corresponding to a dummy current when the prescribed dummy current is fed to the secondary coil 7 by the magnetic coupling of the primary coil 5 and the secondary coil 7; an induction voltage setting part which controls the AC-DC conversion circuit by increasing a current

摘 要 附 图：

when the induction voltage is lower than a coupled induction voltage which is generated when the coils are most efficiently and magnetically coupled to each other so as to reach the coupled induction voltage; and a position

determination part which determines a positional relationship of the coils on the basis of a current value flowing through the primary coil 5. <P>COPYRIGHT: (C)2008,JPO&INPIT 主权项：
