Abstract
An apparatus for transmitting a high efficiency variable power includes a pulse generating unit configured to generate a pulse signal comprising a pulse having a duration corresponding to an amount of power transmitted; a pulse stream generating unit configured to convert the pulse signal to a pulse stream having pulse shape corresponding to the duration of the pulse and data to be transmitted; and a high frequency modulating unit configured to output a variable power by modulating a high frequency signal having a constant amplitude on a time axis by repeatedly outputting and not outputting the high frequency signal based on the pulse stream.
