Description of the Related Art An electromagnetic induction heating cooker receives an output of a rectifying / smoothing circuit by a commercial power source, a rectifying / smoothing circuit for rectifying / smoothing the commercial power source, and a resonance capacitor and a heating coil forming a resonance circuit. It consists of an inverter circuit configured by connecting the output of the resonance circuit to a switching element, and a control device that controls the oscillation of the switching element as a whole. It is generated and induces an eddy current in the load that is magnetically coupled to the heating coil, and the Joule heat causes the load itself to generate heat. In the field of commercial cookers, it does not generate heat itself, but the pan directly generates heat. So
Demand is growing as an alternative to cookers that use gas burners and electric heaters.
