  • Galvanic isolation for isolation transformer
    Patent number: 10743406
    Abstract: The application relates to a galvanic separating apparatus, including a printed circuit board, the printed circuit board including a first soldering pad, a second soldering pad and a recess, whereby the pads are arranged on a lower side of the printed circuit board thereby defining a clearance and/or creepage distance between the pads, and the recess is arranged between the pads, a primary insulated winding layer connected to the first soldering pad and a second insulated winding layer connected to the second soldering part, whereby the winding layers are arranged on an upper side of the printed circuit board, and an insulating layer, whereby the insulating layer extends from the upper side through the recess and protrudes on the lower side beyond the printed circuit board thereby increasing the clearance and/or creepage distance.
    Type: Grant
