Abstract: An aerosol-generating device controls power supplied to a heating unit based on a first target temperature during a first preheating section and control the power based on a second target temperature higher than the first target temperature during a second preheating section, such that the heating unit is stably heated to a target preheating temperature without carbonizing the aerosol generating substrate.
