INDUCTION HEATING APPARATUS AND METHOD FOR CONTROLLING SAME

An induction heating apparatus is configured to determine a third driving frequency corresponding to a third required power value when the required power value of the first working coil or the second working coil is changed to the third required power value, to calculate a difference value between t...

Beschreibung
Zusammenfassung:	An induction heating apparatus is configured to determine a third driving frequency corresponding to a third required power value when the required power value of the first working coil or the second working coil is changed to the third required power value, to calculate a difference value between the driving frequency of the working coil (the required power value of which is not changed) and the third driving frequency, to change an operation mode or a power control mode of the first inverter circuit or the second inverter circuit when the difference value is included in a predetermined first reference range, and to change an output power value of the working coil (the required power value of which is changed) to the third required power value.
