Original Abstract Submitted
An induction heating device according to an embodiment comprises: a working coil which is disposed at a position corresponding to a heating area where an object to be heated is placed, and forms a load together with the object to be heated; a resonant capacitor which forms a resonant circuit together with the working coil; an inverter circuit which includes a plurality of switching elements and supplies a current to the working coil; a first voltage sensor which measures a voltage value applied to the resonant capacitor; a second voltage sensor which measures a supply voltage value supplied to the resonant circuit through the inverter circuit; and a controller which, when the working coil is in operation, calculates at least one of the resistance value of the load and the inductance of the load on the basis of the voltage value of the resonant capacitor and the supply voltage value.
