Abstract (en)

[origin: US5805045A] PCT No. PCT/DE95/01230 Sec. 371 Date Mar. 20, 1997 Sec. 102(e) Date Mar. 20, 1997 PCT Filed Sep. 8, 1995 PCT Pub. No. WO96/09631 PCT Pub. Date Mar. 28, 1996The power supply conductor of a power transformer with foil winding is formed with a plurality of flag-shaped end pieces at one end due to slots running in the longitudinal direction of the foil, which flag-shaped end pieces are folded to form a stack kinked in relation to the longitudinal direction of the foil. The flag-shaped, folded end pieces of the conductor stack must be insulated at least in the area of the edge of the unslotted foil from one another, for example, using insulating foils.
