FIELD: electricity. ^ SUBSTANCE: invention can be used for uninterrupted electric power supply with high-resistant DC voltages 28.5 V and single-phase AC with frequency of 50 Hz 230 V of responsible consumers of various objects (movable and stationary) of industrial and military orientation, which have primary electric power supply from networks 3-50 Hz, 380 V. To the supply unit there introduced is the main and reserve alternating current network, inverters, three commutators, fan unit, fan control circuit, two air temperature sensors, power supply units, voltage sensors, filter of pulse-commutation overvoltages, three radio interference filters, the first, the second and the third transformers, unit of isolating diodes, from the first to the ninth control and indication panels, the first and the second information exchange bus, microcontrollers, filters, current sensors, isolating diode and units of drivers of power switches, from the first to the third group of AC voltage consumers, the first and the second group of stabilised uninterrupted direct current voltage and group of stabilised uninterrupted alternating current voltage. ^ EFFECT: providing continuity of guaranteed electric power supply to consumers with DC and AC voltage. ^ 6 cl, 1 dwg |
