ABSTRACT:
A primary coil and N secondary coils of insulated electrically conductive wire are wound side-by-side about a ferrite core. Every T turns, the wire forming the secondary coils is wound over a separator strip forming an array of loops. A pair of spaced parallel conductors, for displacing the separator strip, are inserted in the array of loops and are soldered to the loops. The loop portion in the space between the conductors is removed. The assembly is covered with a layer of insulating material. The windings are repeated in a second or more layers over the first layer until the desired number of primary and secondary turns is formed.
