Electronic device including resonant charging circuit

An electronic device comprising:

• a battery;
• and
• a power management module electrically connected to the battery and configured to manage a charging or a discharging of the battery;
• wherein the power management module includes:
• a first charging circuit configured to include a first switch group, a first capacitor, and a first inductor;
• a second charging circuit configured to include a second switch group, a second capacitor, and a second inductor;
• and
• a power path distributor configured to distribute power from a first external power supply device or a second external power supply device to the first charging circuit or the second charging circuit, and
• wherein the power management module is configured to:
• identify a connection between the power path distributor and one of the first external power supply device or the second external power supply device;
• determine a type of the connected power supply device;
• when the type of the connected power supply device is a first type, allow the first charging circuit and the second charging circuit to operate in a first mode that allows the first charging circuit and the second charging circuit to each have a fixed voltage conversion ratio such that the battery is charged;
• and
• when the type of the connected power supply device is a second type, allow the first charging circuit and the second charging circuit to operate in a second mode that allows a voltage conversion ratio to be changed corresponding to a charging ratio of the battery such that the battery is charged.
