Original Abstract Submitted

an induction-heating apparatus includes at least two heating coils configured to heat an object to be heated by induction heating, at least two inverter devices connected to the at least two heating coils, respectively, and configured to supply power to the at least two heating coils, respectively, and a controller configured to control the at least two inverter devices. the controller compares driving frequencies, which are frequencies of the power supplied to the at least two heating coils, with each other, and change a driving frequency of a high-frequency coil having a higher driving frequency to a driving frequency of a low-frequency coil having a lower driving frequency. the controller controls an inverter device corresponding to the low-frequency coil in a first control state, and control an inverter device corresponding to the high-frequency coil in a second control state, which is different from the first control state.
