Induktivitätsarmes LeitungspaarLow-inductance line pair

Die Erfindung betrifft ein induktivitätsarmes Leitungspaar.The invention relates to a low-inductance line pair.

Parasitäre Induktivitäten von elektrischen Leitungsverbindungen sind oft schädlich und bewirken Probleme bei höherfrequenter Elektronik, wie z.B. bei Pulswechselrichtern oder Choppern.Parasitic inductances of electrical cable connections are often damaging and cause problems in higher frequency electronics, such as pulse inverters or choppers.

Es sind mehrlagige Schienen- oder Rlattenverbindungen mit Zwischenisolation bekannt,' die aufgrund ihrer nahezu koaxialen Lage zueinander kaum parasitäre Induktivitäten aufweisen. Dafür ergeben sich relativ hohe parasitäre Kapazitäten. Nachteilig ist der erforderliche Raumbedarf derartiger Leiter, der die praktische Anwendung in den modernen Geräten stark einschränkt. Aufgabe der Erfindung ist es, ein induktivitätsarmes Leitungspaar zu schaffen, das kompakt ist und den begrenzten EinbaumMöglichkeiten in modernen Geräten entgegenkommt.Multi-layer rail or batten connections with intermediate insulation are known, which, due to their almost coaxial position relative to one another, have hardly any parasitic inductances. However, relatively high parasitic capacitances result. The disadvantage is the space required for such conductors, which severely limits their practical use in modern devices. The object of the invention is to create a low-inductance pair of conductors that is compact and meets the limited installation options in modern devices.

Diese Aufgabe wird gemäß den kennzeichnenden Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.This object is achieved according to the characterizing features of claim 1. Advantageous embodiments can be found in the subclaims.

Anhand der Zeichnungsfiguren wird die Erfindung näher erläutert.The invention is explained in more detail with reference to the drawing figures.

Fig. 1 zeigt zwei deckungsgleich übereinander angeordnete, elektrisch voneinander isolierte Plattenleiter 1 und 2. Zwischen den Plattenleitern befindet sich eine Isolierschicht entweder Luft oder ein spezielles Isoliermaterial 3. Von dieser an sich bekannten Anordnung wird ausgegangen ;Fig. 1 shows two plate conductors 1 and 2 arranged congruently one above the other and electrically insulated from each other. Between the plate conductors there is an insulating layer, either air or a special insulating material 3. This arrangement, which is known per se, is assumed;

sie bildet praktisch einen Kondensator. Die elektrischen Anschlüsse sind mit 5 bezeichnet. Werden diese Plattenleiter 1, 2 nach der Erfindung paarweise einschließlich Isolation mäanderförmig so zusammengefaltet, wie es Fig. 2 zeigt, dann entsteht ein Paket aus mehreren Lagen übereinander angeordneter Streifen 4 aus elektrischen Leitern. Die elektrischen Anschlüsse 5 sind seitlich an den Rändern der Leiter 1, 2 des obersten und untersten Streifens herausgeführt. Das Paket kann eng gepreßt eine kompakte Schiene bilden. Es finden zweckmäßig dünne isolierte Cu-Platten oder -Folien Verwendung. Im vorliegenden Fall sind die Anschlüsse 5 der Leiter mehrfach mit gleicher Polung (+ oder -) diagonal an den Rändern des obersten und untersten Streifens herausgeführt. Die elektrische Schaltung ist der Fig. 3 nochmals entnehmbar. Die Herstellung einer induktivitätsarmen Leiterschiene aus einem mehrlagigen Faltleiter mit 2 &khgr; &eegr; parallel geschalteter Leiterfolien (für z.B. &eegr; = 2 oder 3) ist möglich.it practically forms a capacitor. The electrical connections are designated 5. If these plate conductors 1, 2 are folded together in pairs including insulation in a meandering shape according to the invention as shown in Fig. 2, then a package is created from several layers of strips 4 of electrical conductors arranged one above the other. The electrical connections 5 are led out laterally at the edges of the conductors 1, 2 of the top and bottom strips. The package can be pressed tightly together to form a compact rail. Thin insulated copper plates or foils are expediently used. In the present case, the connections 5 of the conductors are led out diagonally several times with the same polarity (+ or -) at the edges of the top and bottom strips. The electrical circuit can be seen again in Fig. 3. The production of a low-inductance conductor rail from a multi-layer folded conductor with 2 × η parallel connected conductor foils (e.g. for &eegr; = 2 or 3) is possible.

Durch die Erfindung kann ein kompakter Schienenblock zum Einsatz kommen, der durch seine kapazitiven Eigenschaften vorzüglich zur Kompensation weiterer parasitärer Induktivität einsetzbar ist.The invention enables the use of a compact rail block, which, due to its capacitive properties, is ideal for compensating for further parasitic inductance.
