Effects of transverse displacement of induction devices on coupling coefficient in wireless power transmission system.

Aiming at the problem that how to locate the induction devices' position automatically in the wireless power transmission system, the influence of the transverse displacement of the induction devices on the coupling coefficient between the induction devices is analyzed, and the whole core coil simulation analysis is been done by the large-scale finite element software COMSOL, which have also been verified through experiments. The results show that the coupling coefficient between the induction devices decreases first, then increases, finally decreases with the increase of induction devices' transverse displacement. The theoretical result has positive effect on the efficiency measuring of the whole system, and which is helpful to the research on the automatic location of induction devices. [ABSTRACT FROM AUTHOR]
