Abstract:
A wireless power transmission device wirelessly transmitting power to a wireless power reception device using magnetic resonance according to an embodiment of the present invention comprises a power supply part; a transmission circuit part converting power supplied from the power supply part into power having a frequency for magnetic resonance; a transmission induction coil for coupling the converted power; and a transmission resonance coil disposed around the transmission induction coil and transmitting the coupled power from the transmission induction coil to the wireless power reception device using magnetic resonance, the transmission circuit part being separated from the transmission resonance coil vertically. The prevent invention maximizes power transmission efficiency by controlling a distance between components of the wireless power transmission device. Further, the present invention maximizes the power transmission efficiency by disposing the transmission resonance coil and a second substrate of the wireless power transmission device.
