AUTONOMOUS POWER SUPPLY BASED ON LITHIUM CELLS Russian patent published in 2020 - IPC H02J7/00 H02J9/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used for autonomous power supply of electric receivers of electric energy from batteries based on lithium chemical current sources (LCCS). Device comprises parallel LCCS batteries connected via separating diodes, which in turn are connected to buses of electric receivers through two controllable parallel circuits. Besides, the second branch contains converter of voltage of type of converter, which performs function of voltage stabilization. Control circuit continuously measures voltage on battery LCCS, determines time intervals of converter switching on for voltage stabilization on buses of electric receivers or its disconnection at voltage matching on LCCS battery to allowable voltage deviation range. Both branches contain separating diodes, which provides their uninterrupted switching to operation through converter and back.

EFFECT: technical result consists in improvement of autonomous source power capacity and efficiency factor, as well as in creation of operating mode of self-contained power supply, which allows reducing heat release from voltage converters, which provides longer duration of power supply to consumers from an autonomous source.
