Abstract
The present disclosure relates to a cooking apparatus and a method of controlling the same, and more particularly, to a technology for reducing stress caused by a current flowing through a diode included in the cooking apparatus. The cooking apparatus includes a coil on which a vessel is mounted, configured to form a magnetic field upon application of a current; a first switch and a second switch configured to change a direction of the current flowing through the coil; a first diode connected in parallel to the first switch or a second diode connected in parallel to the second switch; and a controller configured to alternately control a turn-on operation of the first switch and the second switch, and when a maximum value of the current flowing through the first diode or a maximum value of the current flowing through the second diode exceeds a predetermined value, to increase an operating frequency of turning on the first switch and the second switch to limit the maximum value of the current flowing through the first diode or the second diode to less than or equal to the predetermined value.
