An electronic induction heating cooker (200) is provided. The electronic induction heating cooker (200) includes a rectifier (210) that rectifies an input voltage into a direct current (DC) voltage and output the DC voltage, an inverter (220) including first, second and third switches (S1, S2, S3) 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 (230) driven by the AC voltage so as to heat a first cooking container, a second heater (240) connected in parallel to the first heater (230) and driven by the AC voltage so as to heat a second cooking container, and a switching controller (270) that generates a switching signal for controlling the first and second heaters (230, 240) in accordance with a set of operating conditions input thereto and adjusts a duty cycle of the switching signal. |
