Beschreibung
Zusammenfassung:	A method for controlling an induction heating device includes acquiring a temperature value of a high-power working coil, when an absolute value of a difference between a first final driving frequency of a first working coil and a second final driving frequency of a second working coil is equal to or greater than a predetermined noise avoidance value and when a final driving frequency of a low-power working coil differs from a target frequency of the low-power working coil, determining whether the temperature value satisfies a predetermined output change condition, setting a required power value of the high-power working coil to a predetermined minimum power value when the temperature value satisfies the output change condition, and determining the first final driving frequency of the first working coil and the second final driving frequency of the second working coil again.
