  • the general idea on which the invention is based is the compensation of the interference of an electrical circuit (second sub-arrangement) on its surroundings by an arrangement of conductor elements, in which a first sub-arrangement of conductor elements is arranged and arranged according to position and shape and with a second sub-arrangement of conductor elements or an electrical subcircuit is connected in such a way that disruptive influences of the electromagnetic field caused by the arrangement on spatially adjacent third electrical circuits or components are as small as possible.
  • FIG. 1 schematically shows such an arrangement in which the interference (the stray field) of a first inductor L1 (in this case the second sub-arrangement) is to be compensated for by a second inductor Lk (in this case the first sub-arrangement), which has this first inductance is connected in series in the opposite winding direction.
  • This type of switching is intended to ensure that the stray field of the second inductor Lk is opposite to that of the first inductor L1.
  • the desired compensation effect can also be achieved in a good approximation.
  • FIG. 2 shows an exemplary embodiment of the present invention, in which the compensation coil Lk is designed as an approximately spiral air coil, in the center of which the second sub-arrangement is placed, which has an inductance L1.
  • This inductance L1 can also be the effective inductance of the second sub-arrangement in the sense of an equivalent circuit diagram. However, it can also be a discrete coil which is part of the second sub-arrangement, which consists of further components.
  • Such arrangements are particularly advantageous to implement on printed circuit boards or in several layers of the board (so-called multi-layer printed circuit board) of a multi-layer printed circuit or in several layers of an integrated circuit. Due to the availability of several horizontally running layers or layers arranged vertically one above the other in such arrangements, the conductor elements of the partial arrangements can also run vertically one above the other. The necessary electrical connections between the conductor elements can be implemented using suitably placed vias or via holes. Their mutual insulation is brought about by the substrate of the circuit board or suitable insulating layers in the integrated circuit.
  • the turns of the compensation coil Lk shown in FIG. 2 can, for example, run directly one above the other, so that all turns can have the same radius or the geometric properties of the compensation coil can be optimized in a different way without causing insulation or contacting problems would.
  • the first sub-arrangement Lk consists of an air coil with a few turns, which is connected in series with the main inductor Ll in the opposite winding direction.
  • the external magnetic field of the Lges system can be significantly reduced.
  • the invention has a significant reduction in expenditure / costs, simple implementation through space-saving arrangements with a wide range of uses as advantages.
  • the realization by accommodating the air coil on a PCB (printed circuit; printed circuit board) is particularly advantageous.
  • the compensation coil here consists of a few coils
  • Conductor loops Lk which can also run over several layers of the PCB.
  • the actual coil L1 with the opposite winding direction is arranged exactly above it.
  • An application example is the stray field compensation of a DC / DC converter coil using a coil arrangement on a PCB.

Abstract

L'invention concerne un agencement d'éléments conducteurs servant à compenser les influences perturbatrices d'un circuit électrique sur son environnement. Selon l'invention, un premier agencement partiel d'éléments conducteurs est placé et réalisé quant à sa position et à sa forme et est câblé à un deuxième agencement partiel d'éléments conducteurs ou à un circuit partiel électrique de sorte que des influences perturbatrices du champ électromagnétique provoqué par l'agencement sur des circuits ou composants électriques tiers voisins spatialement sont aussi faibles que possible.
