Aerosol-generating device and system comprising an inductive heating device and method of operating the same

An aerosol-generating device, comprising:

• a power source configured to provide a DC supply voltage and a DC current;
• and
• power supply electronics connected to the power source, wherein the power supply electronics are configured to inductively heat a susceptor based on calibration values associated with the susceptor, the power supply electronics comprising:
• a DC/AC converter,
• an inductor connected to the DC/AC converter and being configured to generate an alternating magnetic field when energized hy an alternating current from the DC/AC converter, the inductor being couplable to the susceptor, wherein the susceptor is configured to heat an aerosol-forming substrate, and
• a controller configured to:
• perform a preheating process associated with the susceptor, and
• in response to detecting a control signal associated with an end of the preheating process, perform a calibration process for measuring the calibration values associated with the susceptor.
