TRANSFORMER Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: transformer is built on flexible tape divided into sections which house n-start flat spirals, where n= 1, 2, 3 . . . . In centers of spirals there made holes with inner termination pads located on their edges with junction metallized holes connected to inner turns of n-start spirals. Cuter turns of corresponding n-start spirals are linked to outer termination pads having metallized holes made in them, n-strap spirals are connected into m (m m(m≥n) n) series but electrically isolated chains forming windings of transformer. proper outer termination pads are outputs of transformer. Flexible tape is folded zigzag-like in sections with matching of centers of holes. Central rod of ferromagnetic core is placed into formed through hole coaxial to all n-start spirals. EFFECT: facilitated manufacture. 7 dwg
