AC-TO-DC VOLTAGE TRANSDUCER Russian patent published in 2008 - IPC H02M7/08 

FIELD: electricity.

SUBSTANCE: AC-to-DC voltage transducer provides AC-to-DC voltage transformation for power supply of high-demanding consumers with exclusive standards for rectified voltage quality. It contains two three-phase transformers (1) and (2), forming two phase-shifted relatively to each other at 30 electrical degrees six-phase voltage system expressed with phase leads a, z, b, x, u of six-phase star and with leads a', z,' b', x', c', u' of the second six-phase star, as well as twenty four isolators (3...26) used to form two six-isolator stars, anode of isolators (3), (7), (12), (15), (20), (23) and cathodic of isolators (5), (6), (9), (14), (17), (22) and twelve-isolator ring (isolators (4), (8), (10), (11), (13), (16), (18), (19), (21), (24), (25), (26) so that power electrodes of similar isolators. And each phase of secondary windings of transformer (1) (2) is connected to integrated anodes (cathodes) of two isolators through which it is connected to two phases of secondary windings of transformer (2) (1), having relative phase shift electrical degrees relative to this phase. Common points (27) and (28) of isolator connection of anode and cathodic six-isolator stars respectively form output leads of transducer with connected loading (29). Each connection point of twelve-isolator ring isolator electrodes has connected electrode of the other name and attached to one isolator of six-isolator stars. Thus numbers of secondary phase winding turns of both stars (back stars), comprising six-phase stars are equal, while ratio of numbers of stars secondary phase windings turns (back stars) to numbers of secondary phase winding turns of back stars (stars) is .

EFFECT: twenty-four-fold ripple frequency of rectified voltage.
