POWER SUPPLY UNIT FOR AEROSOL INHALER Russian patent published in 2021 - IPC A24F47/00 H01M14/00 

FIELD: electrical engineering.

SUBSTANCE: power supply unit for the aerosol inhaler contains two consecutive circuits connected to each other in parallel. The non-inverting input of the first operational amplifier is connected to the one of the first node between the load and the first element in the first circuit and to the one of the second node between the second element and the third element in the second circuit, and the inverting input is connected to another one of the first node and the second node. The control circuit is connected to the first operational amplifier and is designed to prevent its differential input value from becoming equal to the potential of its negative power supply input. The potential of the node connected to the non-inverting input has a value lower than the potential of the node connected to the inverting input.

EFFECT: increased accuracy of determining the load temperature used for aerosol formation.
