The present disclosure relates to an induction heating device and a control method thereof. In one embodiment, at a time of a simultaneous operation of a first working coil operating at a first driving frequency and a second working coil operating at a second driving frequency, control for removing interference noise is performed based on a difference between the first driving frequency and the second driving frequency. An induction heating device of one embodiment may adjust the duty ratio of a switching signal provided to a first inverter circuit after adjusting the first driving frequency to adjust the actual output value of the first working coil to a value the same as the required output value of the first working coil.
An induction heating device, comprising:
A control method of an induction heating device, which comprises a first working coil, a first inverter circuit configured to operate at a first driving frequency that corresponds to a first required output value of the first working coil and supplying electric current to the first working coil, a second working coil, and a second inverter circuit configured to operate at a second driving frequency that corresponds to a second required output value of the second working coil, the second driving frequency being greater than the first driving frequency and supplying electric current to the second working coil, the control method comprising:
