INVERTER Russian patent published in 1994 - IPC

FIELD: electrodeposition. SUBSTANCE: device has transformer 4 and interphase reactor 5. Transformer secondary windings 7-9 and 10-12 are connected to direct and inverse three-phase stars, whose neutral conductors are connected to one of the output leads for connection with load 3. The neutral conductor of the direct star is formed by the phase beginnings, and that of the inverse star-by the phase ends. The reactor has magnetic circuit 14 and three three-phase windings 15-17, 18-20 and 20-23, the first winding being short-circuited. The beginnings of the reactor second winding are connected to the beginnings of the direct star. The ends of the reactor third winding are connected to the ends of the inverse star. Taps are made from the ends of the second and beginnings of the third windings of the reactor to connect the input of rectifier 2, whose output is connected to another tap. EFFECT: facilitated procedure. 1 dwg
