THREE-PHASE AC-TO-DC VOLTAGE TRANSDUCER (VERSIONS) Russian patent published in 2017 - IPC H02M7/00 H02M7/06 H01F30/12 

FIELD: electricity.

SUBSTANCE: converter of the first embodiment includes a three-phase transformer with six groups of secondary phase windings and valves, the first group forms a star, the ends of which are connected to the ends of the second group in the left zigzag, and with the end of the third - to the right, the fifth group is connected to the beginnings of a beginning of the fourth group right zigzag and ends - with the beginnings of similar phases of the second group, the sixth group joined in a star, the ends of which are connected to one terminal of the load, the other terminal is connected to the cathodes of the first group of valves, to the anodes of which are connected the start of the second group of windings, to the third and the sixth group are connected through the valves of the second group on the left zigzag, the sixth group are connected to the gates of the third group anodes, cathodes of which are connected to the ends of similar phases of the fourth group, and the reduced numbers of windings of the winding groups in the order of increasing their numbering are: 0.66527; 0.6527; 1; 0.2227; 0.574; 0.3473. The transmitter of the second embodiment includes a three-phase transformer with six groups of secondary phase windings and valves, the first group forms a star, the ends of which are connected to the ends of the second into the left zigzag, and with the end of the third - to the right, the fourth group is connected in star connected beginnings to one conclusion load, the other terminal of which is connected to the cathodes of the first group of valves, to the anodes of which are connected beginning of the second group of coils, the fifth group are connected with the elements of the second group in the right zigzag, and the ends are connected to the cathodes of the valves of the third group, the anodes of which are connected to the ends of the fourth group, forming the fifth group of the compound through the vents on the right zigzag ends of the fourth group are connected to the anodes of valves of the third group, which cathodes are connected to the end of the sixth group, forming the fourth group with a connection through the valves in the left zigzag, the beginning of the third group are connected with the beginnings of the sixth group in the left zigzag, the reduced numbers of windings of the winding groups in order of increasing their numbering are: 0.6527; 0,6527; 0.426; 0.574; 0.574; 0.347.

EFFECT: reduction of rated capacity of the transformer without increasing the number of gates.
