Short distance wireless power transmitting apparatus which enchances wireless power transmitting capability regardless of a relative arrangment with respect to a wireless power receiving apparatus
First 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.

Abstract
Disclosed herein are a coil resonant coupler for short distance wireless power communication and a short distance wireless power transmitting apparatus comprising the same. The coil resonant coupler for short distance wireless power communication comprises a first coil installed perpendicularly to a first axis; a second coil installed perpendicularly to a second axis perpendicular to the first axis; and a third coil installed perpendicularly to a third axis perpendicular to each of the first and second axes. The short distance wireless power transmitting apparatus comprises a primary side core comprising the above-described coil resonant coupler, a position sensing unit which senses a position of the wireless power receiving apparatus to generate position information, and a transmission controlling unit which controls the primary side core based on the position information.
