Claim:
1. A short distance wireless power transmitting apparatus, comprising: a primary side core including: a first coil installed perpendicularly to a first axis; a second coil installed perpendicularly to a second axis perpendicular to the first axis; a third coil installed perpendicularly to a third axis perpendicular to each of the first and second axes; a magnetic focusing plate formed on a same plane as that of the first coil and installed at an inner side of the first coil to focus a magnetic field for improving transmission efficiency; and a fixing bar configured to fix the magnetic focusing plate to the second coil and consisted of a non-conductive material; a position sensing unit sensing a 3-D position of the wireless power receiving apparatus to generate 3-D position information of the wireless power receiving apparatus by using a response signal received from the wireless power receiving apparatus; and a transmission controlling unit controlling the primary side core based on the 3-D position information received from the position sensing unit.
