Abstract

A planar transmitter having a vertical extent and a horizontal extent, having a layer structure with a plurality of electrical circuits, wherein a first electrical circuit and a second electrical circuit are electrically conductively disconnected from one another. The transmitter also has at least one magnetic core which at least partially surrounds the layer structure and acts at least on the first electrical circuit and on the second electrical circuit, wherein the first electrical circuit and the second electrical circuit lie substantially in one plane and form one layer of the layer structure. Provision is further made for at least the first electrical circuit or the second electrical circuit to be subdivided into a plurality of electrical circuits which are electrically conductively disconnected from one another.

Claims

1. A planar transmitter having a vertical extent and a horizontal extent having:

a layer structure with a plurality of electrical circuits, wherein a first electrical circuit and a second electrical circuit are electrically conductively disconnected from one another,

at least one magnetic core, which at least partially surrounds the layer structure and acts at least on the first electrical circuit and on the second electrical circuit,

wherein the first electrical circuit and the second electrical circuit lie substantially in one plane and form one layer of the layer structure,

characterized in that at least the first electrical circuit or the second electrical circuit is subdivided into a plurality of electrical circuits which are electrically conductively disconnected from one another.

2. The transmitter as claimed in claim 1, wherein the transmitter is integrated into a main printed circuit board.

3. The transmitter as claimed in claim 1, wherein the transmitter is designed as a dedicated component.

4. The transmitter as claimed in claim 3, wherein the transmitter is formed on an auxiliary printed circuit board.

5. The transmitter as claimed in claim 4, wherein the auxiliary printed circuit board can be arranged on a main printed circuit board.

6. The transmitter as claimed in claim 1, wherein a printed circuit board is designed as a carrier on which tracks and/or turns and/or wires are arranged.

7. The transmitter as claimed in claim 1, wherein at least one electrical circuit has one or more center taps.

8. The transmitter as claimed claim 1, wherein the transmitter has a plurality of cores.

9. The transmitter as claimed in claim 8, wherein individual or a plurality of electrical circuits at least partially surround a plurality of cores.

10. The transmitter as claimed in claim 1, wherein a minimum distance between the first electrical circuit and a second electrical circuit provides intrinsically safe electrically conductive disconnection.
