ABSTRACT:
In an induction heat cooking apparatus of the invention, an electromagnetic field is generated by a heating coil, and the generated electromagnetic field is supplied to a load so that the load is inductively heated. The cooking apparatus includes an exciter circuit for exciting the heating coil to generate the electromagnetic field; a temperature set circuit for providing a temperature set signal which designates a given target temperature of the load; and a temperature measure circuit for measuring the temperature of the load to generate a temperature measure signal which represents the measured temperature of the load. The cooking apparatus further includes a difference detector circuit for detecting a difference between the temperature set signal and the temperature measure signal and generating a difference signal. The exciter circuit receives the difference signal so as to control heat power for the heating coil.
