UNINTERRUPTED POWER SUPPLY MODULE FOR DC LOADS Russian patent published in 2013 - IPC H02J9/04 

FIELD: electricity.

SUBSTANCE: invention contains utility power converter and molecular energy accumulator connected through isolation diodes to uninterrupted power supply lines of direct current to which the leak-proof cycled accumulator battery is connected through a normally open contact of power contactor of the leak-proof cycled accumulator battery and an isolation diode while charging circuit of molecular energy accumulator is connected through a charging resistor and isolation diode directly to uninterrupted power supply lines of direct current.

EFFECT: simplification of operating mode for leak-proof cycled accumulator batteries, maintenance of guaranteed capacitance and permitted number of charging-discharging cycles for accumulator batteries in compliance with specifications, improvement in reliability of power supply for crucial DC loads for which interruption of power supply is unacceptable.
