Abstract
A planar, in particular intrinsically safe transformer, having: a sandwich-type layer structure having a plurality of layers extending horizontally and arranged vertically on top of one another, including a first and a second conductive layer and at least one insulating inner layer disposed between the two conductive layers, a plurality of electrical circuits, wherein a first electrical circuit and at least a second electrical circuit are galvanically isolated from each other; and at least one ring-type magnetic core having a hole, which acts at least on the first electrical circuit and the second electrical circuit. The core is arranged within the at least one insulating inner layer, a conductor of the first electrical circuit and a conductor of the second electrical circuit each have a winding with at least one winding turn, and the at least one winding turn of the first electrical circuit and the at least one winding turn of the second electrical circuit each run along the first conductive layer and along the second conductive layer and through the at least one insulating inner layer and through the hole of the core.
