Abstract: A pulse transformer arrangement (100) is built from an uncut pulse transformer core (110) and at least one foil winding (120-A, 120-B) (each) comprising multiple insulated conducting strips arranged around the core and ending in foil winding terminals to form multiple independent primary windings. This new design principle has several advantages. Making the winding(s) of foil eliminates the need to cut the core, because of the ease of insertion of the foil winding(s) onto the core. The work to set up a plurality of primary windings is significantly reduced. In addition to the elimination of the costs for cutting the core, this also brings the further advantages of reduced DC  reset current, reduced risk for electrical shorts and avoidance of excessive losses due to potential high frequency AC resistance problems.
