Claims17
An aerosol-generating device comprising:
- a heating element configured to heat an aerosol-generating substrate;
- a battery configured to supply power to the heating element;
- a harvest device configured to generate power;
- and
- a controller configured to control conversion of power generated by the harvest device and control charging of the battery by using converted power,
- wherein the controller is further configured to determine a power generation characteristic of the harvest device based on an operation of the aerosol-generating device and to perform zero-crossing switching control to maximize transmission of the power generated by the harvest device.
