Innovative planar electromagnetic component structure

A transformer comprising:

• a primary circuit comprising a primary winding of N1 turns of an electrical conductor, the primary winding extending from an input primary terminal to an output primary terminal;
• and
• a secondary circuit comprising a secondary winding of N2 turns of an electrical conductor, the secondary winding extending from an input secondary terminal to an output secondary terminal, N1 and N2 being each an integer number greater than or equal to 1;
• the transformer comprising:
• a printed circuit board extending according to a first plane, and comprising a plurality of layers superposed on one another and forming an aperture through the plurality of layers centered around a first axis (Z1), the aperture having a perimeter;
• a ferromagnetic core, disposed around the primary and secondary windings, comprising a central part disposed in the aperture;
• a plurality of vias disposed at a center of the primary and secondary windings along a perimeter of the aperture, and extending through the plurality of layers, each on an axis parallel to the first axis (Z1), the plurality of vias being configured to interconnect the plurality of layers;
• in that one of the N1 turns or one of the N2 turns of the electrical conductor are disposed on each of the plurality of layers, according to any alternation of the N1 turns and the N2 turns,
• wherein each of the N1 turns and each of the N2 turns are wound partially around the plurality of vias from a first via of the plurality of vias to a second via of the plurality of vias to form a circular arc per layer;
• and
• in that each circular arc of one layer is distinctly oriented with respect to the circular arcs of the other layers.
