Definitions
- the invention relates to an inductor with at least one core, the core at least partially enclosing a volume of space with an at least partially concave shape, the inductor having power connections.
- inductance to be an electrical or electronic component with a fixed or adjustable inductance value.
- inductance refers not only to the physical quantity with the unit Henry, but also to the inductive electrical and electronic component.
- inductors are built as passive components to limit currents in electrical lines, temporarily store energy in the form of a magnetic field, and are used to adjust the impedance or for filtering.
- These components known as inductors, include in particular coils, transformers, baluns, chokes and transformers.
- inductance, coil and choke are used synonymously.
- the invention is based on the object of increasing the power density of an inductor.
- connection technology When developing inductors, optimization has so far focused on two main areas. One focus is the area of the choke core and the choke winding. The other focus is connection technology. Depending on performance and depending on Currents, a conventional connection technology can take up to 25% of the total throttle volume.
- the invention solves the problem of increasing the power density for an induction of the type defined at the outset in accordance with the characterizing features of claim 1.
- the invention leads to a higher integration of all throttle components.
- the power connections are arranged at least partially in the spatial volume that is at least partially enclosed by the throttle. This primarily results in a relocation of the connection technology into a previously dead space of the components and also a reduction in the volume of the connection technology as a result of the shortening of the connection paths.
- the invention relates not only to the inductance itself but also to arrangements which have this inductance according to the invention - also according to an advantageous development of the invention.
- a corresponding arrangement with an inductance according to the invention can in particular be a filter assembly or a transformer, each comprising an inductance according to the invention.
- a particularly preferred embodiment of the invention provides that the core of the inductor is designed as a partial ring or as a closed ring.
- the ring or partial ring can have any shape, in particular other than a circular shape, for example oval, egg-shaped, rectangular or polygonal.
- the power connections are elongated, in particular as bolts or power bolts, for electrical contacting of, for example, a circuit board.
- the power connections can have two ends and can be conductively connected to a winding of the inductance in the area of the first end and prepared or provided at a second end for connection to adjacent components.
- the inductor is composed of at least two individual inductors, in which the core at least partially encloses a volume of space with an at least partially concave shape, arranged adjacently in such a way that these individual volumes of space are arranged adjacent to one another, that a common spatial volume is formed from the adjacent spatial volumes of the individual inductors, the power connections of the individual inductors being arranged in the common spatial volume.
- installation space is very advantageously saved with two or more inductors, since several current-conducting connections, e.g. current bolts, can be implemented in a space-saving manner through the two toroidal core chokes in the common volume. This creates an internal wiring of both inductors and the volume of the arrangement is not unnecessarily increased.
- At least one holder element attached to the inductor is arranged in the spatial volume and is mechanically connected to at least some of the power connections in order to hold the power connections in a specific spatial position. It is particularly useful to produce the holding element from injection molding or to produce it as an insulating glass fiber reinforced plate (GRP). Furthermore, the current bolts can be overmolded in a molding process, so that all current bolts and the holder element can be formed into a mechanical unit. It makes sense here if the holder element consists of a non-electrically conductive material or is attached in an electrically insulated manner to at least some of the power connections to be held.
- the holder element can be electrically conductively connected to at least some of the power connections as a component-equipped conductor element or as a component-equipped circuit board. This design not only saves space above the inductance, but also reduces the impedance of the connecting line, since the components, such as capacitors, can be connected for very short periods.
- a particularly preferred application of the invention results from installing the inductor according to the invention from one or more individual inductors in a filter device or filter-integrated frequency converter.
- An advantageous development provides a computer-implemented method for simulating a machine according to the invention or one of its developments.
- a computer system comprising at least one computer is preferably designed and prepared for simulation according to the method.
- the computer or the computer system can advantageously be prepared for this purpose by means of a corresponding computer program product for carrying out a method according to the invention or one of its developments.
- the Figures 1 - 4 each show schematic, simplified, three-dimensional variants of an inductor according to the invention.
- the Figures 2 , 3 and 4 are shown partially sectioned in order to enable a view into the interior - the enclosed volume - of the inductor ID0 according to the invention shown.
- the inductance ID0 of the Figure 1 has an annular core CRE, which has a concave Contour or shape encloses a spatial volume CVT.
- the inductor has power connections TRM.
- the power connections TRM are arranged in the spatial volume CVT, but can also partially protrude from the spatial volume CVT in a manner not shown or be arranged completely in the spatial volume CVT.
- the inductance ID0 uses the space volume CVT, which is always present in, for example, toroidal core/oval and rectangular core chokes and integrates the electrically conductive three-phase connection technology or the TRM power connections into this space. If an order is made in accordance with Figure 4 Further components, for example filter capacitors, are integrated into the CVT, CVC room volume.
- an inductor ID0 according to the invention is shown, the inductor ID0 being composed of two individual inductors ID1, ID2.
- the two individual inductors ID1, ID2 are arranged adjacently in such a way that the spatial volumes CVC are arranged adjacent to one another.
- a common spatial volume CVC is created, formed from the adjacent spatial volumes CVT of the individual inductors ID1, ID2.
- the current connections TRM of the individual inductors ID1, ID2 are arranged in the common spatial volume CVC.
- a holder element CRR attached to the inductance ID0 is clearly visible in the spatial volume CVT.
- the holder element CRR is mechanically connected to the power connections TRM in such a way that the power connections TRM are held in a specific spatial position.
- the holder element CRR is made of a non-current-conducting material or is electrically insulating and is fastened to the power connections TRM to be held.
- the holder element CRR ensures that windings, cores CRE and the power connections TRM or power bolts are held in their position.
- This holder element CRR can be made, for example, from injection molding or an insulating glass fiber reinforced (GRP) plate.
- the current bolts can be overmolded in a molding process so that all power bolts and the insulation holder can become one unit.
- FIG 3 is the inductance ID0 Figure 2 shown in an exemplary combination with adjacent components NEE.
- the connection situation saves space.
- Some power connectors TRM directly contact a printed circuit board PCB and others connect to a separate conductor metal CMT.
- FIG. 4 shows an embodiment or an arrangement ARR with an inductance according to the invention, in which the holder element CRR as a component-equipped circuit board PCB is electrically conductively connected to at least some of the power connections TRM.
- This connection technology enables filter capacitors FCD to be connected, for example, to the midpoint of the two chokes, with a short distance. This is very useful so that no parasitic inductances arise on the filter capacitors.
- the filter capacitors FCD can, for example, be soldered onto the circuit board, which means that the entire system can be assembled much more quickly.
- the filter capacitors can also be connected without a circuit board, for example using wire lines from filter capacitors directly to the current bolts or to the inductors. Further connections of the throttle assembly (input and output of the filter device) are made, for example, using three-phase busbars or flexible or rigid CDC power lines.
- FCD filter capacitors can be integrated into the gap in such a way that they are connected directly to the center of the inductors with short cables.
- FIG. 5 shows a schematic representation of a CMP on one computer - here a CMP on several computers Network WWB comprising a Cloud CLD - running simulation SIM of the inductance ID0 according to the invention.
- the software installed on the CMP computers is a CPP computer program product which, when executed on at least one CMP computer, enables the user to influence or configure and gain knowledge based on the executed SIM simulation using interfaces, for example using a screen and keyboard, so that in particular technical Design decisions can be supported and verified using simulation.

Description
Die Erfindung betrifft eine Induktivität mit mindestens einem Kern, wobei der Kern mit einer zumindest abschnittweisen konkaven Form ein Raumvolumen zumindest teilweise umschließt, wobei die Induktivität Stromanschlüsse aufweist.The invention relates to an inductor with at least one core, the core at least partially enclosing a volume of space with an at least partially concave shape, the inductor having power connections.
Unter einer Induktivität versteht die Erfindung ein elektrisches oder elektronisches Bauelement mit festem oder einstellbarem Induktivitätswert. Der Begriff Induktivität bezeichnet nicht nur die physikalische Größe mit der Einheit Henry, sondern auch das induktive elektrische und elektronische Bauelement. In der Leistungselektronik werden Induktivitäten als passive Bauteile aufgebaut, um Ströme in elektrischen Leitungen zu begrenzen, Energie in Form eines Magnetfeldes zwischenzuspeichern, zur Anpassung der Impedanz oder zur Filterung verwendet. Zu diesen als Induktivitäten bezeichneten Bauelementen zählen insbesondere Spulen, Übertrager, Baluns, Drosseln und Transformatoren. In der Folge werden die Begriffe Induktivität, Spule und Drossel synonym benutzt.The invention understands an inductance to be an electrical or electronic component with a fixed or adjustable inductance value. The term inductance refers not only to the physical quantity with the unit Henry, but also to the inductive electrical and electronic component. In power electronics, inductors are built as passive components to limit currents in electrical lines, temporarily store energy in the form of a magnetic field, and are used to adjust the impedance or for filtering. These components, known as inductors, include in particular coils, transformers, baluns, chokes and transformers. In the following, the terms inductance, coil and choke are used synonymously.
Wie alle anderen Bauteile in der Leistungselektronik werden auch bei den Induktivitäten immer größere Leistungsdichten gefordert, um noch kompaktere Filterkomponenten oder filterintegrierte Frequenzumrichter zu entwickeln.Like all other components in power electronics, ever greater power densities are required for inductors in order to develop even more compact filter components or filter-integrated frequency converters.
Der Erfindung liegt die Aufgabe zugrunde, die Leistungsdichte einer Induktivität zu erhöhen.The invention is based on the object of increasing the power density of an inductor.
Bei der Entwicklung von Induktivitäten wird bisher an zwei Schwerpunkten optimiert. Ein Schwerpunkt ist der Bereich des Drosselkerns und der Drosselwicklung. Der andere Schwerpunkt ist die Anschlusstechnik. Je nach Leistung und je nach Strömen kann eine herkömmliche Anschlusstechnik bis zu 25% von Gesamt-Drosselvolumen annehmen.When developing inductors, optimization has so far focused on two main areas. One focus is the area of the choke core and the choke winding. The other focus is connection technology. Depending on performance and depending on Currents, a conventional connection technology can take up to 25% of the total throttle volume.
Die Erfindung löst die gestellte Aufgabe, die Leistungsdichte zu erhöhen, für eine Induktion der eingangs definierten Art gemäß den kennzeichnenden Merkmalen des Anspruchs 1. Die Erfindung führt zu einer höheren Integration aller Drosselbauteile.The invention solves the problem of increasing the power density for an induction of the type defined at the outset in accordance with the characterizing features of claim 1. The invention leads to a higher integration of all throttle components.
Im Einzelnen ist vorgesehen, dass zumindest einige der Stromanschlüsse zumindest teilweise in dem Raumvolumen, das von der Drossel zumindest teilweise umschlossen ist, angeordnet sind. Dadurch ergibt sich vor allem eine Verlagerung der Anschlusstechnik in einen bisherigen Totraum der Bauteile und außerdem eine Verringerung des Volumens der Anschlusstechnik infolge der Verkürzung der Verbindungswege. Die Erfindung betrifft nicht nur die Induktivität selbst sondern auch Anordnungen, die diese erfindungsgemäße Induktivität - auch gemäß einer vorteilhaften Weiterbildung der Erfindung - aufweisen. Eine entsprechende Anordnung mit einer erfindungsgemäßen Induktivität kann insbesondere eine Filterbaugruppe oder ein Transformator jeweils umfassend eine erfindungsgemäße Induktivität sein.In detail, it is provided that at least some of the power connections are arranged at least partially in the spatial volume that is at least partially enclosed by the throttle. This primarily results in a relocation of the connection technology into a previously dead space of the components and also a reduction in the volume of the connection technology as a result of the shortening of the connection paths. The invention relates not only to the inductance itself but also to arrangements which have this inductance according to the invention - also according to an advantageous development of the invention. A corresponding arrangement with an inductance according to the invention can in particular be a filter assembly or a transformer, each comprising an inductance according to the invention.
Eine besonders bevorzugte Ausführungsmöglichkeit der Erfindung sieht vor, dass der Kern der Induktivität als Teil-Ring oder als geschlossener Ring ausgebildet ist. Hierbei kann der Ring oder Teil-Ring eine beliebige Form aufweisen, insbesondere abweichend von einer Kreisform, zum Beispiel auch oval, eiförmig, rechteckig oder vieleckig sein.A particularly preferred embodiment of the invention provides that the core of the inductor is designed as a partial ring or as a closed ring. The ring or partial ring can have any shape, in particular other than a circular shape, for example oval, egg-shaped, rectangular or polygonal.
Eine vorteilhafte Weiterbildung sieht vor, dass die Stromanschlüsse länglich ausgebildet sind, insbesondere als Bolzen oder Strombolzen, zur elektrischen Kontaktierung von zum Beispiel einer Leiterplatte. Insbesondere können die Stromanschlüsse zwei Enden aufweisen und im Bereich des ersten Endes mit einer Wicklung der Induktivität leitend verbunden sein und an einem zweiten Ende zum Anschluss an benachbarte Bauelemente vorbereitet oder vorgesehen sein.An advantageous development provides that the power connections are elongated, in particular as bolts or power bolts, for electrical contacting of, for example, a circuit board. In particular, the power connections can have two ends and can be conductively connected to a winding of the inductance in the area of the first end and prepared or provided at a second end for connection to adjacent components.
Eine andere besonders vorteilhafte Weiterbildung sieht vor, dass die Induktivität aus mindestens zwei Einzel-Induktivitäten, bei denen der Kern mit einer zumindest abschnittweisen konkaven Form ein Raumvolumen zumindest teilweise umschließt, derart benachbart angeordnet zusammengesetzt ist, dass diese einzelnen Raumvolumina zueinander angrenzend angeordnet sind, dass ein gemeinsames Raumvolumen gebildet aus den angrenzenden Raumvolumina der Einzel-Induktivitäten gebildet ist, wobei die Stromanschlüsse der Einzel-Induktivitäten in dem gemeinsamen Raumvolumen angeordnet sind. Auf diese Weise wird bei zwei oder mehreren Induktivitäten sehr vorteilhaft Bauraum eingespart, da mehrere stromleitende Verbindungen z.B. Strombolzen, durch die beiden Ringkerndrosseln im gemeinsamen Raumvolumen platzsparend durchgeführt werden können. Somit entsteht eine interne Verdrahtung von beiden Induktivitäten und das Volumen der Anordnung wird nicht unnötig vergrößert.Another particularly advantageous development provides that the inductor is composed of at least two individual inductors, in which the core at least partially encloses a volume of space with an at least partially concave shape, arranged adjacently in such a way that these individual volumes of space are arranged adjacent to one another, that a common spatial volume is formed from the adjacent spatial volumes of the individual inductors, the power connections of the individual inductors being arranged in the common spatial volume. In this way, installation space is very advantageously saved with two or more inductors, since several current-conducting connections, e.g. current bolts, can be implemented in a space-saving manner through the two toroidal core chokes in the common volume. This creates an internal wiring of both inductors and the volume of the arrangement is not unnecessarily increased.
Zur Verbesserung der mechanischen Integrität ist es besonders vorteilhaft, wenn in dem Raumvolumen mindestens ein an der Induktivität befestigtes Halterelement angeordnet ist, dass mit zumindest einigen der Stromanschlüsse mechanisch verbunden ist, um die Stromanschlüsse in einer bestimmten räumlichen Position zu halten. Besonders zweckmäßig ist es, dass Haltelement aus Spritzguss herzustellen oder als eine isolierende glasfaserverstärkte Platte (GFK) herzustellen. Weiterhin können die Strombolzen in einem Molding-Verfahren umspritzt werden, so dass alle Strombolzen und das Halterelement zu einer mechanischen Einheit ausgebildet werden können. Hier ist es sinnvoll, wenn das Halterelement aus einem nicht stromleitenden Material besteht oder elektrisch isoliert an zumindest einigen der zu halternden Stromanschlüssen befestigt ist.To improve the mechanical integrity, it is particularly advantageous if at least one holder element attached to the inductor is arranged in the spatial volume and is mechanically connected to at least some of the power connections in order to hold the power connections in a specific spatial position. It is particularly useful to produce the holding element from injection molding or to produce it as an insulating glass fiber reinforced plate (GRP). Furthermore, the current bolts can be overmolded in a molding process, so that all current bolts and the holder element can be formed into a mechanical unit. It makes sense here if the holder element consists of a non-electrically conductive material or is attached in an electrically insulated manner to at least some of the power connections to be held.
Alternativ kann das Halterelement als Bauteil-bestücktes Leiterelement oder als Bauteil-bestückte Leiterplatte elektrisch leitend mit zumindest einigen der Stromanschlüsse verbunden sein. Diese Ausbildung spart nicht nur Platz oberhalb der Induktivität, sondern reduziert auch die Impedanz der verbindenden Leitung, da die Bauteile, beispielsweise Kondensatoren, sehr kurz angeschlossen werden können.Alternatively, the holder element can be electrically conductively connected to at least some of the power connections as a component-equipped conductor element or as a component-equipped circuit board. This design not only saves space above the inductance, but also reduces the impedance of the connecting line, since the components, such as capacitors, can be connected for very short periods.
Eine besonders bevorzugte Anwendung der Erfindung ergibt sich bei einem Einbau der erfindungsgemäßen Induktivität aus einer oder mehreren Einzel-Induktivitäten in ein Filtergerät oder filterintegrierten Frequenzumrichter.A particularly preferred application of the invention results from installing the inductor according to the invention from one or more individual inductors in a filter device or filter-integrated frequency converter.

- 2) Zwei oder mehrere Induktivitäten können; aufeinandergestapelt und mit z.B. innengeführten Stromanschlüssen bzw. Strombolzen untereinander platzsparend verschaltet werden;
- 3) Eine derartig neuartig verknüpfte Baugruppe bzw. Induktivität ermöglicht ein direktes Anschließen von benachbarten Bauelementen z.B. Filterkondensatoren mit einer kurzen Distanz ohne parasitäre Induktivitätsanteile
- 4) Die Herstellung so einer erfindungsgemäßen Induktivität kann in einer halb- oder vollautomatisierten Montage; erfolgen, da die Stromanschlüssen bzw. Strombolzen ideal zueinander ausgerichtet sind;
- 5) Im Innenraum eingesetzte Halterelemente isolieren die Stromanschlüsse zueinander und halten die Wicklung der Induktivität in einem definierten Abstand zu den Kernen;
- 6) Die erfindungsgemäße Gestaltung ermöglicht eine Anbindung weiterer Bauteile, z.B. Filterkondensatoren, im Zwischenraum an die Drossel.
- 1) Applications with internal power connections enable more compact connection technology than with usual power connections placed outside the inductors
- 2) Two or more inductors can; stacked on top of each other and interconnected to save space using, for example, internal power connections or power bolts;
- 3) Such a newly linked assembly or inductance enables neighboring components, such as filter capacitors, to be connected directly over a short distance without parasitic inductance components
- 4) The production of such an inductor according to the invention can be carried out in a semi- or fully automated assembly; occur because the power connections or power bolts are ideally aligned with one another;
- 5) Holder elements used in the interior isolate the power connections from each other and keep the inductance winding at a defined distance from the cores;
- 6) The design according to the invention enables additional components, such as filter capacitors, to be connected to the choke in the gap.

Alternativ können in dem Zwischenraum die Filterkondensatoren FCD so eingebunden werden, dass sie direkt mit kurzen Leitungen an den Mittelpunkt der Induktivitäten angebunden sind. Diese Anordnungen sparen nicht nur Platz oberhalb der Induktivität ID0 sondern reduzieren auch die Impedanz der Verbindungsleitungen, da die benachbarten Bauelemente sehr kurz angeschlossen sind.Alternatively, the FCD filter capacitors can be integrated into the gap in such a way that they are connected directly to the center of the inductors with short cables. These arrangements not only save space above the inductance ID0 but also reduce the impedance of the connecting lines because the neighboring components are connected very briefly.
