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.

Induction heating device and method for controlling induction heating device

An induction heating apparatus may include first/second working coils, first/second inverter circuits, and a controller. When a user changes a required power value of a first working coil or a second working coil to a third required power value, a controller determines a third driving frequency corresponding to the third required power value. The controller calculates a difference value between a driving frequency of the working coil, the required power value of which is not changed, and the third driving frequency, and compares the calculated difference value with a first reference range. When the calculated difference value is included in the first reference range, the controller changes an operation mode of a first inverter circuit from a full bridge mode to a frequency doubler mode, and changes an output power value of the working coil, the required power value of which is changed to the third required power value.

Induction heating apparatus and method for controlling same

Disclosed herein is an induction heating device capable of reducing interference noise. The induction heating device includes a first power module supplying power for driving to at least one of a first working coil and an inner coil, a second power module supplying power for driving to at least one of a second working coil and an outer coil, and a control unit controlling supply of power by the first power module and the second power module. In an embodiment, the control unit may cut off supply of power to the outer coil when an instruction for heating to at least one of a first heating area and a second heating area, and an instruction for heating to a third heating area are input.

Induction heating device capable of reducing interference noise

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.
