1. An induction heat cooking apparatus comprising:
a rectifier configured to convert an alternating current (AC) voltage supplied from a power source into a direct current (DC) voltage;
a battery configured to store power;
a switch that is configured to connect to at least one of the rectifier based on the induction heat cooking apparatus operating in a wired mode and that is configured to connect to the battery based on the induction heat cooking apparatus operating in a wireless mode;
a charger that is configured to connect to the power source and charge the battery based on the induction heat cooking apparatus operating in the wired mode and that is configured to stop charging the battery based on the induction heat cooking apparatus operating in the wireless mode;
an inverter connected to the switch and configured to receive a first voltage from at least one of the rectifier or the battery and convert the first voltage to a second voltage; and
a heating coil configured to receive the second voltage from the inverter and generate magnetic fields, the heating coil being configured to heat a cooking device based on the generated magnetic fields.
