Abstract

An induction heating apparatus according to one embodiment 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.
