POWER TRANSFER APPARATUS AND METHOD FOR TRANSFERRING ELECTRIC POWER
First Claim
1. A power transfer apparatus, comprising:
- a first device having a primary coil, the first device being configured to produce primary power through the primary coil upon being supplied with external power and to be controlled by a provided control signal so that the primary power decreases and increases upon the control signal representing a first value and a second value, respectively; and
a second device having a secondary coil, the second device being configured to be joined with the first device so that the secondary coil is electromagnetically coupled with the primary coil, the second device being configured to produce secondary power upon the secondary coil being driven through the electromagnetic coupling, the second device being configured to provide the first device with the control signal representing the first value and the second value upon the secondary power being greater and smaller than a reference value, respectively.

Abstract
A power transfer apparatus including a first device and a second device having a first coil and a second coil, respectively, is provided. The first device is configured to produce primary power through the primary coil upon being supplied with external power and to be controlled by a provided control signal so that the primary power decreases and increases upon the control signal representing a first value and a second value, respectively. The second device is configured to be joined with the first device so that the secondary coil is electromagnetically coupled with the primary coil. The second device is configured to produce secondary power upon the secondary coil being driven through the electromagnetic coupling. The second device is configured to provide the first device with the control signal representing the first value and the second value upon the secondary power being greater and smaller than a reference value, respectively.

13. A method for transferring electric power from a first device to a second device, the first device and the second device including a primary coil and the secondary coil, respectively, comprising:
-
joining the first device and the second device with each other so that the primary coil and the secondary coil are electromagnetically coupled with each other; producing primary power through the primary coil by supplying the first device with external power; producing secondary power by driving the secondary coil through the electromagnetic coupling; providing the first device with a control signal representing a first value and a second value upon the secondary power being greater and smaller than a reference value, respectively; and controlling the primary power by means of the control signal so that the primary power decreases and increases upon the control signal representing the first value and the second value, respectively. - View Dependent Claims (14, 15, 16)
