Abstract
An induction heating cooker is provided. The induction heating cooker may include a rectifier to rectify an input voltage into a direct current (DC) voltage and output the DC voltage, an inverter to generate an alternating current (AC) voltage by switching the DC voltage, a first heater driven by the AC voltage so as to heat a first cooking container, a second heater connected in parallel to the first heater, and driven by the AC voltage so as to heat a second cooking container, and a switching controller configured to output a switching signal to the inverter for controlling the first and second heaters in accordance with a selected operation mode. The selected operation mode may be a first operation mode for driving only the first heater, a second operation mode for driving only the second heater, or a third operation mode for driving both the first and second heaters at the same time.
