Abstract
According to an embodiment, an aerosol generating device includes a reservoir storing an aerosol generating material, a vibrator generating ultrasonic vibration to atomize the aerosol generating material into an aerosol, a drive circuit applying an alternating current (AC) voltage to the vibrator, a feedback circuit outputting a voltage proportional to a current supplied to the drive circuit, and a processor controlling a pulse width modulation (PWM) signal applied to the drive circuit, such that a value corresponding to the voltage is in a preset range defined by a first upper limit and a first lower limit.
