Abstract
The invention concerns a planar transformer winding comprising primary and secondary coils with wire turns produced in the form of strip conductors formed on the surfaces of an insulting base and electrically connected with one another by means of conducting holes bored in the insulating base. The primary and secondary winding portions borne by one common surface of the insulating base are joined together by winding, along two distinct overlapping zones, spiral in shape, one of the zones joining side by side turns or portions of turns of the primary coil and the other zone joining together the turns or portions or turns of the secondary coil. Such an arrangement enables to obtain primary and secondary coils with a different number of turns on one single insulating base with two surfaces.
