Abstract: The disclosure relates to an induction heating device and a method of controlling the induction heating device. The induction heating device includes a first working coil and a second working coil. According to an embodiment of the disclosure, a driving start time of the first working coil and a driving start time of the second working coil are determined based on a driving scheme of the first working coil, a driving scheme of the second working coil, and a predetermined driving period. According to an embodiment of the disclosure, an eccentricity determination period of the first working coil and an eccentricity determination period of the second working coil are determined based on the driving scheme of the first working coil, the driving scheme of the second working coil, the driving period, a duty cycle of the first working coil, and a duty cycle of the second working coil.

Abstract: The method for controlling an induction heating device according to the present disclosure may include receiving a driving command for a second working coil when a first working coil is being driven at a first target frequency, stopping driving of the first working coil and driving the second working coil at a preset first adjustment frequency, determining a second target frequency of the second working coil corresponding to the driving command for the second working coil, determining a final driving frequency of the first working coil and a final driving frequency of the second working coil based on the first target frequency and the second target frequency, respectively, driving the first working coil and the second working coil simultaneously at a second adjustment frequency, and adjusting a driving frequency of the first working coil and a driving frequency of the second working coil to the final driving frequency, respectively.
