PURPOSE: A wireless power transmission device and a method thereof are provided to have an effect of improving the energy transmission efficiency by transmitting energy through a power transmitter. CONSTITUTION: A wireless power transmission device (60) comprises a power supply unit (11), plural power transmitters (20), and a control unit (15). The wireless power transmission device wirelessly transmits electricity to a receiver by using magnetic resonance. The power supply unit is composed to supply electricity. Plural power transmitters transmit electricity to the wireless power receiver. The control unit determines at least one power transmitter transmitting electricity to the receiver from the plural power transmitters. The power supply unit supplies electricity having at least one mutual combination coefficient determined among at least one power transmitter and the wireless power receiver.
