Abstract:
Disclosed herein is an induction heat cooking apparatus including a power supply configured to supply an alternating current (AC) voltage, a rectifier configured to rectify the supplied AC voltage into a direct current (DC) voltage, first and second switching units configured to control switching such that the DC voltage from the rectifier is alternately applied to a working coil, a comparison unit configured to sense current flowing in the working coil and to compare the sensed current with a predetermined reference value to output pulses, and a controller configured to determine whether a cooking vessel is present on the working coil based on the output pulses.
