Abstract:
PURPOSE: A wireless power transmitting device and a transmitting method thereof are provided to prevent instantaneous discharging by sequentially supplying power to multiple power receiving devices depending on the order of priority. CONSTITUTION: A power transmitting part(410) wirelessly transmits power. The transmission uses multiple power transmission coils. A power receiving device(500) charges the transmission power of the power transmission part. A power transmission control part determines the order of priority when the number of power receiving devices exceeds one. The power transmission control part transmits the power depending on the order of priority.

Abstract:
PURPOSE: A power transmission device for a wireless power communication system is provided to remove electric charge accumulated in a parasitic capacitor by grounding a coil and a metal layer. CONSTITUTION: A circuit board(170) comprises an insulation layer and a ground. The ground is formed on the insulation layer. A core of a magnetic material is arranged on the circuit board and comprises recessed portions(152,153). Wire coils(110) are received in the recessed portions. One end of the wire coils receives power through the circuit board. A metal layer is arranged between the core and the insulation layer and is grounded on the ground.
