Abstract
The present invention relates to an induction heating apparatus. In order to cope with various types of containers without increasing an operating frequency of an induction heating apparatus, the present invention compares a resistance value of a container with a predetermined reference resistance value, and determines an operating mode of a switching device according to a result of the comparison. According to the present invention, it is possible to use various types of containers without increasing an operating frequency of an induction heating apparatus, by adjusting a resonance frequency of a working coil according to a resistance value of a container used in the induction heating apparatus.
