摘要 |
A printed circuit board (10) including a layered transformer (1) has a stack of layers of a first magnetic layer (2), a first transformer coil (4), an insulating body (7), a second transformer coil (5) and a second magnetic layer (3), wherein each of the transformer coils (4, 5) is embodied as a two-dimensional pattern of conductive tracks. The insulating body may comprise one of more channels (8, 18, 28) containing a magnetic material. Instead of one printed circuit board (10), the transformer (1) may be embodied in two printed circuit boards (60) as well, each comprising a magnetic layer (2) and a transformer coil (4). Said printed circuit boards may be included in a charger device (71) and a user device (72).
