Abstract

A method of controlling an aerosol-generating system, and aerosol-generating system, and an aerosol-generating device for an aerosol-generating system. The aerosol-generating system comprises: an inductive heating arrangement configured to heat an aerosol-forming substrate; and a power supply configured to supply power to the inductive heating arrangement. The inductive heating arrangement comprises: an inductive heating element (10) including at least one susceptor (12, 14) that is heatable by penetration with a varying magnetic field to heat the aerosol-forming substrate; a first inductor coil (32); and a second inductor coil (34). The method comprises: driving a first varying current in the first inductor coil to generate a first varying magnetic field for heating a first portion of the inductive heating element, and controlling the first varying current such that the temperature of the first portion of the inductive heating element increases from an initial temperature to a first operating temperature. The method further comprises: driving a second varying current in the second inductor coil to generate a second varying magnetic field for heating a second portion of the inductive heating element, and controlling the second varying current such that the temperature of the second portion of the inductive heating element increases from an initial temperature to a second operating temperature. The second varying current is not driven when the first varying current is driven, and the first varying current is not driven when the second varying current is driven.
