Non-contact power transmission apparatus
First Claim
1. A method for controlling a power transmission in a non-contact power transmission device, the method comprising:
- receiving a header ID code from a non-contact power receiving apparatus;
transmitting a full ID requesting signal to the non-contact power receiving apparatus if the header ID code is received; and
transmitting a wireless power signal to the non-contact power receiving apparatus if a normal ID code is received in response to the full ID requesting signal.

Abstract
A non-contact power transmission apparatus accurately determines the kind of object that is placed on the charging deck of the non-contact power transmission apparatus, and, only when a non-contact power receiving apparatus is placed on the power transmission apparatus, allows power transmission and data communication to take place, thereby accurately determining the state of the receiver side and efficiently controlling the transmission of power. In the power transmission apparatus, the power supplied to the non-contact power receiving apparatus is measured, and the output power of the wireless power signal output from two different cores is controlled, thereby allowing the charging operation to be stably conducted even if the non-contact power receiving apparatus is moved anywhere on the power transmission apparatus. The power transmission apparatus improves both the reliability of operation of the non-contact charging system, and the competitiveness of related products, such as portable terminals, battery packs and the like.

11. A non-contact power transmission apparatus comprising:
-
a primary core configured to transmit a wireless power signal and a full ID requesting signal; an ID identifier configured to analyze and process an ID code from a non-contact power receiving apparatus; and a power transmission controller configured to transmit the full ID requesting signal to the non-contact power receiving apparatus if a header ID code is received from the non-contact power receiving apparatus, and transmit the wireless power signal to the non-contact power receiving apparatus if a normal ID code is received in response to the full ID requesting signal. - View Dependent Claims (12, 13, 14, 15, 16)
