STATIC CONVERTER TRANSFORMER Russian patent published in 1997 - IPC

FIELD: converter engineering; high-frequency voltage changers for output voltage regulation. SUBSTANCE: transformer has magnetic circuit built up of four toroidal ribbon cores made of narrow hyssteresis square loop magnetic material and simultaneously wound with primary winding turns; each core carries different number of turns according to expression W_p2≥2W_p1; , where is number of turns on cores k=1, 2, 3; it also has windings for separating cores according to magnetization reversal current interconnected cumulatively in series and connected to reactance. Voltage is regulated with reference to mean output voltage picked off output winding carried by first core and regulation accuracy is determined by flatness of hysteresis square loop sections. EFFECT: improved design. 4 dwg
