ELECTRONIC CIRCUIT FOR MULTIPLE INDUCTION ELEMENTS IN AEROSOL-GENERATING DEVICE Russian patent published in 2021 - IPC A24F47/00 

FIELD: electricity.

SUBSTANCE: invention relates to electronic circuit for multiple induction elements in aerosol generating device. Electronic circuit for multiple induction elements in aerosol generating device is developed. Each of induction elements is intended for inductive heating of one or several current collectors, which provide for use of aerosol-forming material heating. Electronic circuit comprises a plurality of drivers, each of which is configured to generate alternating current from the input DC for the corresponding induction element during operation. Each driver comprises one or more first transistors, each of which is controlled by a switching potential in order to allow passage of current through them during operation. Circuit also comprises a converter configured to increase the input voltage in order to form a switching potential during operation which is common for the entire plurality of drivers. Invention also relates to an aerosol generation device. Inductive heating of current collector is controlled and, consequently, control of aerosol-forming material heating, that is aerosol generation process control by the device as a whole.

EFFECT: use of converter for supply of switching potential required for switching of transistors of drivers, switching potential of which is higher than potential from accumulator, eliminates need to use separate direct current source or accumulator, and, consequently, reduces the cost and complexity of the chain, and hence the aerosol-generating device as a whole; since converter is common for all drivers, provides switching potential supply to each driver, eliminating the need to use a separate converter for each of the drivers to supply a switching potential thereto, which reduces the complexity and cost of the electronic circuit.
