CONTROL APPARATUS, WIRELESS POWER TRANSMISSION SYSTEM AND WIRELESS POWER TRANSMISSION APPARATUS
First Claim
1. A control apparatus for a first wireless power transmission apparatus and a second wireless power transmission apparatus, the first wireless power transmission apparatus including a first inductor and an alternating-current signal source that supplies an alternating-current power to the first inductor, and the second wireless power transmission apparatus including a second inductor that receives the alternating-current power wirelessly from the first inductor, comprising:
- a position controller which controls a phase relationship of current flowing in the first inductor and the second inductor such that attractive force or repulsive force is generated between the first and second inductors, and adjusts a relative position of the first inductor and the second inductor by use of the attractive force or the repulsive force.

Abstract
According to one embodiment, there is provided a control apparatus for a first wireless power transmission apparatus and a second wireless power transmission apparatus. The first wireless power transmission apparatus includes a first inductor and an alternating-current signal source that supplies an alternating-current power to the first inductor. The second wireless power transmission apparatus includes a second inductor that receives the alternating-current power wirelessly from the first inductor. The position controller controls a phase relationship of current flowing in the first inductor and the second inductor such that attractive force or repulsive force is generated between the first and second inductors, and adjusts a relative position of the first inductor and the second inductor by use of the attractive force or the repulsive force.
