Abstract: An aerosol generating device includes an accommodator for accommodating a cigarette through an opening formed at an end of the accommodator, a first susceptor located in the accommodator, a second susceptor disposed a predetermined distance away from the first susceptor, a coil that generates an alternating magnetic field for the first and second susceptors to generate heat, and a temperature sensor arranged proximate to the second susceptor to measure a temperature profile of the second susceptor. The temperature profile of the second susceptor corresponds to a temperature profile of the first susceptor, and a temperature of the first susceptor is determined based on the temperature profile of the second susceptor.

Abstract: An aerosol generating device includes a battery, a heater for heating an aerosol generating material, a voltage converter, and a controller. An aerosol generating device is provided with a voltage converter that is arranged between a battery and a heater, and converts a voltage applied from the battery to a constant voltage to output a preset fixed voltage that is applied to the heater. A controller controls electric power supplied to the heater such that the preset fixed voltage is applied to the heater in a preheating mode.

Abstract: According to some embodiments, an aerosol generating device may include a battery, a first control circuit configured to convert power received from the battery into a pulse width modulation (PWM) signal, a heater configured to heat an aerosol generating article based on the PWM signal received from the first control circuit, and a second control circuit configured to transmit an instruction for causing the first control circuit to generate the PWM signal, in response to a user input to the first control circuit. The first control circuit may determine abnormal operation of the second control circuit, and the second control circuit may determine abnormal operation of the aerosol generating device. Accordingly, the aerosol generating device may determine a more specific operation state and prevent abnormal operation of the heater.
