Abstract

The author describes the development of a novel induction cooking range for heating not only special iron vessels but also nonmagnetic and low-resistivity metal vessels such as aluminum pans, which cannot be heated by conventional induction ranges. Input resistances of exciting coils together with the various metal vessels were investigated, and the optimum characteristics of a high-frequency inverter were determined. The inverter has double-layer coils and two resonance-circuit capacitors. Proper coils and frequencies are automatically selected through the detection of the vessel material. The induction range can also prevent undesirable levitation of light aluminum vessels on the top plate by monitoring the variation of the resonance frequency
