  • Apparatus and method for transmitting wireless power
    Patent number: 9831719
    Abstract: The present invention relates to an apparatus and a method for transmitting wireless power, and more particularly, to an apparatus and a method for transmitting wireless power that rapidly and precisely adjusts impedance so as to transmit desired power. Disclosed an apparatus for transmitting wireless power that performs wireless power transmission, including: an oscillator; an amplifier; an impedance matcher including a matching network which adjusts impedance according to a digital control signal and an analog signal, a sensor, a digital controller which outputs a digital control signal, and generates an analog control start signal when adjustment of the impedance by the digital control signal is completed, and an analog controller which outputs the analog control signal, and a transmitting antenna which radiates the magnetic field by using the transmission power.
