Claim 0:
1. An aerosol-generating device in which an accommodation space for accommodating an aerosol-generating substrate is formed, wherein a susceptor included in the aerosol-generating substrate is heated in an induction heating method, the aerosol-generating device comprising:
a battery for supplying direct current (DC) power;
a power converter including at least one switching element and configured to convert the DC power into alternating current (AC) power;
a coil that is wound along the accommodation space, extends in a lengthwise direction of the aerosol-generating device, and is configured to heat the susceptor by applying an alternating magnetic field, of which a direction periodically changes, to the susceptor included in the aerosol-generating substrate according to the AC power converted by the power converter; and
a controller configured to control a time to supply a current to the coil in a state where a duty and a frequency of the current are fixed so that a temperature of the susceptor reaches a target temperature that is preset.
