Embodiment Construction

[0012] The invention is described in more detail below with reference to the accompanying drawings. It should be noted here that the different aspects described can each be used individually or in combination with each other. That is, each aspect can be used in conjunction with the different embodiments of the invention, as long as it is not explicitly stated as a pure alternative.

[0013] Also, for simplicity below, only one entity is generally used. But as long as there is no explicit note, the present invention can also have more relevant entities respectively. In this respect, the use of the words "a", "an" and "an" should only be understood as meaning that at least one entity is used in a simple embodiment.

[0014] Whenever a process is described below, the various steps of the process can be arranged and / or combined in any order, unless the context clearly dictates otherwise. Furthermore, the described sequences - (unless otherwise expressly indicated) - can be comb...

Abstract

The invention relates to a current sensor (S1) having a carrier (PCB), wherein a first patterned electrical plane (E1) is arranged on or in the carrier, and wherein a second patterned electrical plane(E2) is arranged on or in the carrier, wherein a first patterned section (L1) of the first patterned electrical plane is connected to a second patterned section (L2) of the second patterned electrical plane by means of electrical contact, such that a loop (S) is formed, with the result that a current flow change of an electrical conductor (M), which is arranged substantially parallel to the carrier and is arranged substantially perpendicular to the loop, causes an induction voltage in the loop formed in this manner.

Description

technical field [0001] The invention relates to a current sensor. Background technique [0002] Current sensors are known prior art. A current sensor measures the current as a shunt, but alternatively by measuring the magnetic field surrounding the current. [0003] Resistance-based current measurements require access to the running system, while indirect measurements via surrounding magnetic fields can also be added. [0004] These indirect measuring devices are often based on the principle of air-core coils. The air-core coil can be realized, for example, on a circuit board or as a discrete component such as a Rogowski coil. [0005] Rogowski coils consist of air-core coils in which the conductors of the sensor are wound onto a ring-shaped structure through which the conductor to be measured is guided. This arrangement has the advantage that it is very insensitive to changes in the position of the current-carrying conductor and can therefore be used independently of th...
