FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering. Proposed circuit comprises input interface (5) to receive power from power source (6) and output interface (11) to feed preset electric power to load (4), and multiple capacitors (2), multiple control thermistors and multiple switches (3), each being connected to appropriate capacitor (2). Each switch (3) is wired to switch from 1st operating state, whereat it closes the circuit connecting load (4), appropriate capacitor (2) and power supply circuit (6) to 2nd operating state whereat it does not close aforesaid circuit. Control unit (12) changes the state of switches (3) between aforesaid 1st and 2nd states to control power fed to load (4), and determines condensance connected in between source (6) and load (4).
EFFECT: higher accuracy and reliability.
