Abstract
A non-contact power charging, in which power transmission can be interrupted when foreign materials are deposited on a charge plate of the non-contact power charging system. A charging operation can be continuously maintained at a stable voltage even if a non-contact power receiving apparatus moves by touching or displacement on the charge plate of the non-contact power charging system in the charging operation. Charging efficiency is improved.

6. A method of controlling a non-contact power charging system, comprising:
-
generating a power transmission signal in a non-contact power transmission apparatus and transmitting the power transmission signal to a non-contact power receiving apparatus to charge the receiving apparatus; receiving charging information from the receiving apparatus; and adjusting a level of the power transmission signal transmitted to the receiving apparatus by adjusting a frequency of the power transmission signal, based on the charging information received from the receiving apparatus. - View Dependent Claims (7, 8, 9, 10, 11, 12)
