  • Abstract A half-bridge series resonant inverter is implemented to recognize the parameters of the equivalent circuit model of an induction coil loaded with steel pots for induction cookers. When a steel pot is loaded on the induction coil, the circuit parameters and thus the resonant frequency vary with the shape and material of the pot. The effects of the inverter switching frequency and the position between the pot and the induction coil are analyzed from experimental tests with seven pots of different shapes and materials. Accordingly, the parameters of the equivalent circuit can be expressed as equations with functions of the switching frequency. The derived circuit model can be used for determining the operating ranges of the output power and the switching frequency of the resonant inverter loaded by specified pots with similar operating characteristics. The parameter derivation method to two exemplar design cases of 2.5-kW and 3.3-kW inductor cookers has been validated by experimental tests.
