PROBLEM TO BE SOLVED: To control the temperature of a pan correctly and easily by providing a high linearity relation between a power instruction and an output power by a simple circuit structure. SOLUTION: This inverter device makes a pan 19 generate heat by means of electromagnetic induction heating by virtue of a high frequency magnetic field which is generated by supplying power to a magnetic field generation coil 12 at switching period of the on-time Ton obtained based on a power instruction Pr, and generating the high frequency magnetic field corresponding to the output power of the magnetic field generation coil 12. This device has an on-time determination circuit 40 to obtain the on-time Ton so as to make the output power shown by the power instruction Pr coincide with the output power of the magnetic field generation coil 12. |
