Abstract
An aerosol generating device includes: a cartridge including a liquid storage and an atomizer; and a main body including a battery, a puff sensor, and a controller configured to perform pulse width modulation (PWM) control for supplying power from the battery to the atomizer, wherein the controller performs the PWM control at a first duty ratio during a puff period and performs the PWM control at a second duty ratio lower than the first duty ratio during a non-puff period between puff periods.
