Abstract: PURPOSE: A power transmission method and apparatus thereof are provided to effectively offer power to a power reception apparatus by solving power supply problems. CONSTITUTION: A control unit(18) senses load conversion states which is more than the threshold value set by a voltage and current measurement unit.
