  • Planar transformer
    Patent number: 8258910
    Abstract: A planar transformer suitable for intrinsically safe electronic circuits with a core, a first printed circuit board and a second printed circuit board. The first printed circuit board has a first winding and the second printed circuit board has a second winding. The planar transformer can be produced at a low cost and is compact, but is still suitable for connection to intrinsically safe operating circuits is implemented by at least one gap being asymmetrically split on the first printed circuit board and the second printed circuit board.
    Type: Grant
