PURPOSE:To make it possible to increase a heating output according to an input setting value by comparing a value associated with the heating operation of a heating means with the input setting value, thereby controlling the on-time of a switching means according to the result of the comparison. CONSTITUTION:A heating means 7 for heating an object to be heated by causing an eddy current in the object to be heated by means of magnetic flux generated by electromagnetic induction heats the object to be heated with a heating output commensurate with the on-time of a switching means 13. A comparison means 25 for comparing an input value VSET related to the heating output for heating the object to be heated with the value VR1 associated with the heating operation of the heating means 7 controls the on-time of the switching means 13 according to the compared result of the comparison means 25. Thus the heating output can be increased according to the input setting value. |
