connections are done as a third step in assembling the module 21 of fig2 four connecting strap 23 25 27 and hidden but shown in fig5 29 may be soldered connecting respective windings 7 and 7 11 and 11 9 and 9 and 5 and 5 of modules 1 and 2 this will be further discussed and illustrated below the order of assembly suggested is for illustration only not a limitation the assembly may be made in any order or simultaneously and the resulting assembly 21 is the same the exposed ends of the metal foil windings 9 and 7 of module 2 may be the output terminations of the module 21 and may as an illustration not a limitation be soldered to leads of a rectifier package in a power converter fig3 shows the module 1 of fig1 partially assembled the magnetic core 3 is shown in phantom so that the internal configuration of the metal foil windings 5 and 7 may be seen each is a 90 degree helix and each has its respective ends bent to conform to the outside of the magnetic core 3 to be terminations of the respective metal foil windings the metal foil winding 5 may be made from copper foil as shown in fig6 in fig6 the dashed lines indicate bends as is further illustrated in fig7 a c fig7 a c show a metal foil winding 7 which is the same as the metal foil winding 5 of fig6 however the orientation of the formed winding 7 corresponds in position to the metal foil winding 7 of the other drawings all of the windings in this example are the same except for orientation.
