Document Type and Number:
WIPO Patent Application WO/2014/115949
Kind Code:
A1
Abstract:
The present invention relates to a method and a system for wirelessly transmitting electric power, and a computer-readable recording medium. According to an aspect of the present invention, provided is a system for wirelessly transmitting electric power, the system including a transmission antenna, a reception antenna spaced apart from the transmission antenna by a changing distance, and a source consisting of a D type power amplifier for supplying electric power to the transmission antenna. According to the present invention, even in an environment in which an operation frequency of a wireless power transmission system is fixed and the distance between the transmission antenna and the reception antenna changes, a high power transmission efficiency can be maintained only through a simple control of the D type power amplifier or load impedance.
