Classification: CPC H | IPC H

Claim 7:
8. A control method of a cooking apparatus on which a vessel is placed, the method comprising:
detecting a magnitude of an input current applied differently according to a type of the vessel and a magnitude of an input voltage of the cooking apparatus;
determining a type of the vessel placed on the coil according to a power value calculated based on the detected input current and input voltage; and
determining a heating mode of the cooking apparatus based on the determined type of vessel,
wherein the cooking apparatus includes:
a coil on which the vessel is placed, and configured to form a magnetic field upon application of a current,
a first switch and a second switch connected to the coil and serially connected to each other,
a first capacitor and a second capacitor connected between one end of the first switch and the second switch and the coil, and connected in parallel to each other, and
a relay switch connected to one end of the second capacitor, and the determining a heating mode includes:
determining the heating mode as a first mode for turning off the relay switch based on the determination that the type of the vessel placed on the coil is a non-ferromagnetic cell, and
determining the heating mode as a second mode for turning on the relay switch based on the determination that the type of the vessel placed on the coil is a non-ferromagnetic vessel.
