DEVICE AND METHOD FOR CONTROLLING AN ELECTRICAL HEATER TO LIMIT TEMPERATURE

摘要

There is disclosed a method of controlling an electrical heating element, comprising: maintaining the temperature of the heating element at a target temperature during a plurality of heating phases by supplying electrical power to the heating element; limiting the power supplied to the heating element during each heating phase to a threshold power level, such that a variable B, where B is equal to the threshold power level divided by the target temperature, is progressively reduced with increasing time following activation of the heating element. There is also disclosed a device for controlling a heating element and an aerosol-generating system including a heating element controlled in accordance with the method.
