Abstract
An electronic device according to various embodiments may include: a coil configured to receive a signal for wirelessly obtaining power from an external electronic device; a wireless power circuit (MFC) configured to output the signal received by the coil as a DC signal; a first capacitive voltage divider circuit configured to adjust the voltage of, and to output, power according to a first voltage division ratio; a second capacitive voltage divider circuit configured to adjust the voltage of, and to output, power according to a second voltage division ratio; a controller configured to control the electronic device to provide the DC signal to at least one capacitive voltage divider circuit among the first capacitive voltage divider circuit and the second capacitive voltage divider circuit, based on a voltage value of the signal received through the coil; and a battery configured to receive another signal output from the at least one capacitive voltage divider circuit, based on the provided DC signal, thereby obtaining power.
