FIELD: electricity.
SUBSTANCE: to network 1 m converting units 2 are connected. Units contain switches 3, transformers 4, converting bridges 5. Number of bridges in each unit is n. Units 2 are connected to line wire 7 through reactors 6. Second output of units 2 is connected to grounding 9 through earthing line wires 8. Substation converts one type of current (DC, AC) to other and connects so AC network 1 to DC line 7. Novelty is that transformer of one branch is shifted relative to transformer of another unit at angle of 60/mn electric degrees. Reduction of higher harmonics at direct and alternating current sides.
EFFECT: reduction of noise and energy losses, higher reliability.
