Abstract
An inductive heating device, an aerosol-generating system, and a method of operating the device are provided. The device is configured to receive an aerosol-generating article including an aerosol-forming substrate and a susceptor, and to heat the susceptor when the article is received by the device, the device including a DC power supply; and power supply electronics configured to supply power to the inductor in a plurality of pulses separated by time intervals, for heating the susceptor when the article is received by the device, the pulses including two or more heating pulses and one or more probing pulses between successive heating pulses, and to control a duration of a time interval between the successive heating pulses based on one or more measurements of the current supplied from the DC power supply in one or more of the one or more probing pulses.
