Abstract
There is provided an inductive heating device 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 to provide a DC supply voltage and a DC current; and power supply electronics including a DC/AC converter connected to the power supply, and an inductor connected to the converter to inductively couple to the susceptor when the article is received by the device, the electronics being configured to supply power to the inductor from the power supply, via the converter, for heating the susceptor when the article is received by the device, the supplied power being provided in a plurality of pulses separated by time intervals, and to control a duration of the time intervals between successive pulses based on measurements of the current provided by the power supply.
