Publication number: 20240122252Abstract: A method for controlling the heating of a susceptor of an aerosol-generating device is described, the susceptor being inductively heated by an oscillating circuit driven by an inverter at an operating frequency. The method includes a power delivery mode of the aerosol-generating device, a step of updating the operating frequency being performed during the power delivery mode and including the following sub-steps: determining, using a controller, the resonant frequency of the oscillating circuit during heat of the susceptor; and setting, using the controller, the operating frequency at the determined resonant frequency. The updating step is continuously repeated during power delivery mode of the aerosol-generating device.Type: ApplicationFiled: February 4, 2022Publication date: April 18, 2024Applicant: JT International SAInventors: Branislav Zigmund, Stefan Lojek, Daniel Vanko, Petr Konvicný, Stanislav Sliva
