POWER SUPPLY UNIT OF INHALATION COMPONENT GENERATION APPARATUS AND METHOD FOR SELECTING VALUE OF ELECTRICAL RESISTANCE OF KNOWN RESISTOR IN POWER SUPPLY UNIT OF INHALATION COMPONENT GENERATION APPARATUS Russian patent published in 2021 - IPC A24F40/51 A24F40/90 H02J7/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, particular to power supply units. The technical result is achieved by the fact that the power supply unit includes a power source connected with the first resistor, a second resistor connected in series with the first resistor, a connecting part electrically connectable to an external unit, wherein said unit includes a first electrical lead connected with a first assembly between the first resistor and the second resistor, and a second electrical lead connected with a second assembly located on the side opposite from the first assembly relative to the first resistor, a first switch connected with the first assembly and forming an electrical branch in parallel with the second resistor, and a detecting part detecting connection of the external unit to the connecting part by the value of the voltage drop at the second resistor. The first switch includes a body diode so that the current flow direction is a reverse direction when the external unit is not connected to the connecting part.

EFFECT: ensuring reliable and efficient use of the power supply.
