Abstract:
It is an object of the present invention to provide an induction heating apparatus that can enable a plurality of heating coil to perform heating by sharing a inverter having semiconductor switches in use, thereby adjusting a power without increasing losses of the semiconductor switches so much with respect to the respective heating coils, the present invention being configured such that the inverter alternately outputs drive signals respectively having each of two operating frequencies to the plurality of heating coils in every predetermined operation lapse of time and the plurality of heating coils are respectively connected to capacitance circuits in the inverter to have the different frequency characteristics.
