MAGNET-THYRISTOR FREQUENCY MULTIPLIER (OPTIONS) Russian patent published in 1998 - IPC

FIELD: electrical engineering; static power supplies. SUBSTANCE: output transformer is provided, in addition, with taps from primary windings and with secondary winding, and ferromagnetic phase converter has (n+3)/2 phases for factor-of-five frequency multiplication or (n+1)/2 phases for factor-of-nine frequency multiplication, where n is conversion ratio; it also has additional pairs of thyristors connected on one end to output terminals of output transformer primary windings and on other end, to common points of main thyristor pairs; primary winding taps of output transformer are connected to common points of main thyristor pairs. EFFECT: reduced mass and size and improved reliability of frequency multiplier due to simplified design. 2 cl, 8 dwg
