Abstract
An electronic device includes a plurality of coils, power conversion circuits, demodulation switches, and a processor. The power conversion circuits convert DC power into AC power, and output the AC power to the plurality of coils, respectively. The demodulation switches selectively connect the plurality of coils to ground. The processor selects at least one coil from among the plurality of coils, and controls an on/off state of the demodulation switches to connect or disconnect at least one remaining coil except for the selected at least one coil among the plurality of coils to the ground. The processor controls the power conversion circuits to output the AC power to the selected at least one coil and demodulates a signal of the selected at least one coil to identify information from an external electronic device disposed adjacent to a selected at least one coil based on the demodulation.
