INPUT AND OUTPUT POWER UNITS CONFIGURED TO ENSURE SELECTIVE POWER FOR UNINTERRUPTED POWER SUPPLY Russian patent published in 2016 - IPC H02J9/06 

FIELD: electricity.

SUBSTANCE: invention can be applied to electrical engineering. Uninterrupted power supply ("UPS") has input unit with multiple inputs (L1, L2, L3, B1, B2; B3) and at least one connecting element (100, 102, 104, 106), configured for selective connection of at least one input of plurality of inputs and at least one other input of plurality of inputs. Multiple inputs and at least one connecting element can be made and arranged to selectively obtain following configurations: single energy supply, single-phase input and single-phase output; double energy supply, single-phase input and single-phase output; single energy supply, three-phase input and single-phase output; double energy supply, three-phase input and single-phase output; single energy supply, three-phase input and three-phase output; and double energy supply, three-phase input and three-phase output. Additionally other versions of implementation are disclosed, as well as methods of selective production of various energetic configurations.

EFFECT: providing metering of varying power requirements of uninterrupted power supply.
