WIRELESS POWER SUPPLY SYSTEM USING A MAGNETIC RESONANCE AND NOTEBOOK USING THE SAME

摘要

PURPOSE: A wireless power supply system using magnetic resonance and a notebook computer cooler using the same are provided to enable a user to safely use a notebook computer and improve the charging convenience by inducing power supply to the notebook computer. CONSTITUTION: A power transmission device (210) comprises a power supply unit (211), a drive circuit part (213), a source coil (215), and a transmission resonant coil (217). The power supply unit receives the AC power supply, and converts into the rated DC power supply to drive the circuit. The drive circuit part oscillates the DC power supply to a resonance frequency. The source coil performs the AC oscillation based on the voltage and the resonance frequency. The transmission resonant coil is installed to be closed to the source coil, and induces magnetic resonance. A notebook computer cooler (220) comprises a reception resonant coil (221), a device coil (223), and a DC converter (225). The reception resonant coil performs the magnetic resonance. The device coil produces electricity by magnetically binding with the reception resonant coil. The DC converter supplies the rated DC power to a notebook computer. The notebook computer cooler is installed to be separated from the power transmission device, supplies the electric energy to a notebook computer and charges the computer.
