Abstract
An electronic induction heating cooker is provided. The electronic induction heating cooker may include a rectifier that rectifies an input voltage into a direct current (DC) voltage and output the DC voltage, an inverter including first, second and third switches connected in series between a positive power source terminal and a negative power source terminal 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 that generates a switching signal for controlling the first and second heaters in accordance with a set of operating conditions input thereto and adjusts a duty cycle of the switching signal.
