THREE-PHASE RECTIFIER Russian patent published in 2017 - IPC H02M7/06 

FIELD: electricity.

SUBSTANCE: invention relates to field of conversion equipment. Three-phase rectifier consists of transformer with two secondary windings (1) and (2), each connected in triangle, gates (3–8) connected in closed ring, wherein secondary winding (1) each phase winding is connected to secondary winding 2 opposite phases through two gates. Thus, phase winding ax is via gates (3) and (8) is connected by two phase windings b'y' and c'z' of secondary winding (2). Between similar clamps a and a' of phase windings ax and a'x' load (9) is connected. Rectified voltage at load (9) generation takes place as result of secondary windings (1) triangle phase EMF summation with triangle (2) EMF through gates (3–8). Thus, "ax" phase EMF together with "zc" phase EMF causes passage of current through each of gates (3–8) for 60 el. degrees, which will close through clamp x' and load (9). Similarly, from winding "by" clamp "b" current flows for 60 electrical degrees through gate (7) of winding c'z'; y'b' to load (9). Phase winding cz together with ax winding causes current flow for 60 electrical degrees through gates (4) and (5) windings of c'z'; y'b' to load (9). Thus, voltage at load has six-fold pulsation frequency, and current flow duration via gate makes 60 electrical degrees. Leaking to gates triangles linear currents have duration of 120 electrical degrees.

EFFECT: invention can be used in DC consumers supply.
