Claims

[Scope of utility model registration request]

The switching element is turned on by the pulse signal of the control circuit,
The AC current is turned off to convert the direct current into an alternating current, and this alternating current is applied to the heating coil.The resonant circuit between the heating coil and the capacitor converts the alternating current into a high frequency current, and this high frequency electrode applies high frequency to the heating coil. In an electromagnetic cooker that generates a magnetic field to heat a cooking pot,
A detector for detecting the amount of output fluctuation of the heating coil that occurs depending on the material and size of the cooking pot, and a duty ratio of the pulse signal that is changed so as to suppress the amount of output fluctuation detected by the detector. An electromagnetic cooker characterized by being provided with a correction circuit.
