Abstract (en)
A printed circuit board (1) having: at least one insulating plate (3) provided with a plurality of conductive tracks (4) defining respective electrical conductors; and an inductor device (2), which is supported by the insulating plate (3), is electrically connected to the conductive tracks (4) and has a toroidal magnetic core (6) and at least one coil (8) arranged around the toroidal magnetic core (6). The inductor device (2) has a plurality of conductive rigid bars (9), which are "U"-shaped, are arranged astride the toroidal magnetic core (6) and each have two straight legs (10) connected to one another by a cusp (11). The insulating plate (3) has a plurality of through holes (5), each engaged by an end of a corresponding leg (10) of a conductive bar (9). The insulating plate (3) has conductive tracks (4), which connect the legs (10) of the conductive bars (9) so as to create an electrical circuit, which is part of the inductor device (2) and closes the conductive bars (9) around the toroidal magnetic core (6) so as to define respective turns of the coil (8).
