MULTIPHASE INDUCTION REGULATOR Russian patent published in 2003 - IPC

FIELD: electrical engineering; voltage regulation. SUBSTANCE: regulator has toroidal magnetic core incorporating star-connected multiphase primary winding . It is fixed in position relative to toroidal magnetic core incorporating three- phase secondary winding. Phase number of primary winding is a multiple of three to six or more. Starting phase leads of both windings are electrically connected to wiping contacts of switching unit enabling connection of respective primary phase leads to those of three-phase supply mains and to respective starting phase leads of secondary winding. Secondary winding phase leads are connected to load. EFFECT: simplified design, facilitated manufacture, reduced material input, enhanced operating reliability, reduced mass, size, and cost. 1 cl, 4 dwg
