Problems solved by technology

However, even if the heaters are made of the same size and the same material, resistance variations may occur between the heaters due to various factors including manufacturing tolerances, so the heaters may may also be heated to different temperatures depending on its electrical resistance
This is a problem because the desired smoking experience may not be consistently provided to users of aerosol-generating devices

Abstract

Provided is an aerosol generating device including a heater that heats an aerosol-generating material and a controller that controls power supplied to the heater. The controller may measure a resistance value of the heater by using at least one electrical characteristic associated with the heater, select any one power profile from among a plurality of pre-stored power profiles including values ofpower to be supplied to the heater, such that a temperature of the heater reaches a target temperature within a predetermined time from a time point at which power supply to the heater is initiated regardless of variation in the resistance value of the heater, and control power supplied to the heater according to the selected power profile.

Description

technical field [0001] One or more embodiments relate to aerosol-generating devices and methods of operating aerosol-generating devices. Background technique [0002] Recently, demand for cigarette substitutes to replace ordinary cigarettes has increased. There is an increasing need for methods of generating aerosols not by burning cigarettes but by heating aerosol-generating substances in cigarettes. Therefore, studies on heated cigarettes or heated aerosol generating devices are actively being conducted. [0003] A heater included in the aerosol-generating device heats the aerosol-generating substance. In order to generate aerosol uniformly at an appropriate level, it is very important to control the power supplied to the heater according to the desired temperature profile. However, even if the heaters are made of the same size and the same material, resistance variations may occur between the heaters due to various factors including manufacturing tolerances, so the hea...
