FIELD: electricity. ^ SUBSTANCE: system comprises multiple units of power accumulation, line of power supply arranged with the possibility to supply and receive electric power between loading device and system of power supply. Multiple units of voltage transformation, between according units of power accumulation and specified power supply line, unit of operation mode selection, selecting mode of operation, in which operation of voltage transformation is permitted in single unit of voltage transformation, and operation of voltage transformation in other unit of voltage transformation is stopped. And unit of selection in unit of voltage transformation, which switches between units of voltage transformation, when output voltage of power transformation unit, corresponding to unit of voltage transformation, performing operation of voltage transformation, below output voltage of power accumulation unit, corresponding to unit of voltage transformation, operation of voltage transformation in which is stopped, by value that exceeds specified threshold voltage. ^ EFFECT: increased stability of power supply. ^ 13 cl, 16 dwg |
