摘要： There is provided an inductive heating assembly to inductively heat an aerosol-forming substrate to an operating temperature, the assembly including an induction source connected to a DC power supply to generate an alternating electromagnetic field to inductively heat a susceptor assembly including a first susceptor and a second susceptor having a Curie temperature below the operating temperature, and a controller operatively connected to the induction source and the DC power supply, to determine an actual apparent resistance of the susceptor assembly indicative of the actual temperature of the susceptor assembly, to determine a minimum value of the apparent resistance occurring during pre-heating of the susceptor assembly, and to control operation of the induction source such that the actual apparent resistance corresponds to the determined minimum value of the apparent resistance plus a pre-determined offset value of the apparent resistance to control heating of the substrate to the operating temperature.
