Abstract
An electronic device may include: a battery, a resonant circuit including a receiving coil, at least one capacitor and at least one switch, a rectifier circuit; a DC/DC converter, a charge control circuit; and a controller, wherein the controller may be configured to check the voltage outputted from the rectifier circuit, control the at least one switch so that the receiving coil and the at least one capacitor form a serial resonant circuit, if the voltage output from the rectifier circuit is greater than or equal to a threshold voltage, and control the at least one switch so that the receiving coil and the at least one capacitor form a parallel resonant circuit, if the voltage output from the rectifier circuit is less than the threshold voltage.
