Definitions
- the invention relates to a high-voltage ignition transformer for igniting and operating AC high-pressure gas discharge lamps in motor vehicles, with a core, with a primary winding surrounding the core, which consists of a film and with a secondary winding surrounding the core, which consists of a film, an insulating film being arranged between the individual layers of the primary winding and the secondary winding.
- a high-voltage ignition transformer for igniting and operating high-pressure gas discharge lamps is known, the primary winding and the secondary winding of which are wound from a film.
- the material of the core of the high-voltage ignition transmitter consists of air.
- the exemplary embodiment shown relates to a high-pressure gas discharge lamp for use in the home, the high-pressure gas discharge lamp having a socket for screwing into commercially available lamps.
- the turns of the high voltage ignition transformer are wound on the end part of the glass bulb of the lamp.
- Such a high-voltage ignition transformer is not suitable for use in motor vehicles because, on the one hand, the high-pressure gas discharge lamps used in the home and in the motor vehicle area differ and, on the other hand, the dimensions for the efficiency that can be achieved using an air core and the required dielectric strength for the previously known embodiment are too large for an application in the motor vehicle.
- the invention is therefore based on the object of creating a high-voltage ignition transformer for AC high-pressure gas discharge lamps in motor vehicles, which has a current-independent secondary inductance, which has the smallest possible dimensions and which has a simple and inexpensive, high-voltage-compatible winding structure with the highest possible efficiency.
- the core is designed as a stretched core, that the stretched core consists of a soft magnetic ferrite material and that the core has a cross-sectional area and the secondary winding has a number of turns in which the core is unsaturated in all operating conditions .
- the core is designed as an elongated core, because thus the secondary inductance of the high-voltage ignition transformer can be dimensioned almost independently of current and thus irregularities in the operating current, which, for. B. complicate the control of a constant light output, as well as sudden changes in the large starting currents can be safely and reliably avoided, since the core can not go into saturation.
- the high-voltage ignition transformer can have the smallest possible dimensions and a breakdown-proof high-voltage-compatible winding structure is achieved with the highest possible efficiency.

- the primary winding and the secondary winding each have one turn per layer of the film, because thus the very high winding voltage is at the same time the layer voltage, which is isolated by the insulating film and the Primary winding is automatically evenly distributed over the entire winding width, even with a minimum number of turns, so that there is an optimal coupling between the primary winding and the secondary winding and, in addition, partial saturations of the ferrite core are avoided.
- the insulating film arranged between the individual layers of the primary winding and the secondary winding is wider than the film of the primary winding and the secondary winding, because this results in a particularly high security against flashovers with a simple and inexpensive construction.

- the core is a rod core, which results in a particularly simple and inexpensive embodiment in which there is no saturation of the soft magnetic ferrite core.
- the core has the shoulders supporting the windings results in the advantage that the field lines do not emerge as far from the end regions of the stretched soft magnetic ferrite core as in the case of a stretched core which does not have such shoulders, as a result of which eddy current losses in adjacent metal parts such as B. a housing can be reduced.

Abstract
Description
Die Erfindung betrifft einen Hochspannungs-Zündübertrager zum Zünden und Betreiben von Wechselstrom-Hochdruck-Gasentladungslampen in Kraftfahrzeugen, mit einem Kern, mit einer den Kern umgebenden Primärwicklung, die aus einer Folie besteht und mit einer den Kern umgebenden Sekundärwicklung, die aus einer Folie besteht, wobei zwischen den einzelnen Lagen der Primärwicklung und der Sekundärwicklung eine Isolierfolie angeordnet ist.The invention relates to a high-voltage ignition transformer for igniting and operating AC high-pressure gas discharge lamps in motor vehicles, with a core, with a primary winding surrounding the core, which consists of a film and with a secondary winding surrounding the core, which consists of a film, an insulating film being arranged between the individual layers of the primary winding and the secondary winding.
Aus der europäischen Patentanmeldung 0 391 470 A1 ist ein Hochspannungs-Zündübertrager zum Zünden und Betreiben von Hochdruck-Gasentladungslampen bekannt, dessen Primärwicklung und dessen Sekundärwicklung aus einer Folie gewickelt ist. Das Material des Kerns des Hochspannungs-Zündübertragers besteht hierbei aus Luft.From European patent application 0 391 470 A1, a high-voltage ignition transformer for igniting and operating high-pressure gas discharge lamps is known, the primary winding and the secondary winding of which are wound from a film. The material of the core of the high-voltage ignition transmitter consists of air.
Das gezeigte Ausführungsbeispiel bezieht sich auf eine Hochdruck-Gasentladungslampe zur Verwendung im Hausbereich, wobei die Hochdruck-Gasentladungslampe eine Fassung zum Einschrauben in handelsübliche Leuchten aufweist. Die Windungen des Hochspannungs-Zündübertragers sind auf das Endteil des Glaskolbens der Lampe aufgewickelt. Ein derart ausgebildeter Hochspannungs-Zündübertrager ist für die Verwendung in Kraftfahrzeugen nicht geeignet, da zum einen die verwendeten Hochdruck-Gasentladungslampen im Haus- und im Kraftfahrzeugbereich sich unterscheiden und zum anderen die Abmessungen bei dem erreichbaren Wirkungsgrad unter Verwendung eines Luftkerns und der erforderlichen Durchschlagfestigkeit bei der vorbekannten Ausführungsform für eine Anwendung im Kraftfahrzeug zu groß sind. Dies gilt insbesondere deshalb, weil bei der Zündung von Hochdruck-Gasentladungslampen in Kraftfahrzeugen Zündspannungen in der Größenordnung von 20 KV benötigt werden und der Hochspannungs-Zündübertrager bei der Erzeugung derart hoher Spannungen aus der Bordspannung eines Kraftfahrzeugs einen möglichst hohen Wirkungsgrad bei möglichst geringen Abmessungen und einer möglichst hohen Durchschlagfestigkeit aufweisen muß.The exemplary embodiment shown relates to a high-pressure gas discharge lamp for use in the home, the high-pressure gas discharge lamp having a socket for screwing into commercially available lamps. The turns of the high voltage ignition transformer are wound on the end part of the glass bulb of the lamp. Such a high-voltage ignition transformer is not suitable for use in motor vehicles because, on the one hand, the high-pressure gas discharge lamps used in the home and in the motor vehicle area differ and, on the other hand, the dimensions for the efficiency that can be achieved using an air core and the required dielectric strength for the previously known embodiment are too large for an application in the motor vehicle. This is particularly true because when High-pressure gas discharge lamps in motor vehicles require ignition voltages of the order of 20 KV and the high-voltage ignition transformer must have the highest possible efficiency with the smallest possible dimensions and the highest possible dielectric strength when generating such high voltages from the on-board voltage of a motor vehicle.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Hochspannungs-Zündübertrager für Wechselstrom-Hochdruck-Gasentladungslampen in Kraftfahrzeugen zu schaffen, der eine stromunabhängige Sekundärinduktivität aufweist, der möglichst geringere Abmessungen aufweist und der bei einem möglichst hohen Wirkungsgrad einen einfachen und kostengünstigen, hochspannungsgerechten Wicklungsaufbau hat.The invention is therefore based on the object of creating a high-voltage ignition transformer for AC high-pressure gas discharge lamps in motor vehicles, which has a current-independent secondary inductance, which has the smallest possible dimensions and which has a simple and inexpensive, high-voltage-compatible winding structure with the highest possible efficiency.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kern als ein gestreckter Kern ausgebildet ist, daß der gestreckte Kern aus einem weichmagnetischen Ferrit-Material besteht und daß der Kern eine Querschnittsfläche und die Sekundärwicklung eine Windungszahl aufweist, bei der bei allen Betriebsbedingungen der Kern ungesättigt ist.The object is achieved in that the core is designed as a stretched core, that the stretched core consists of a soft magnetic ferrite material and that the core has a cross-sectional area and the secondary winding has a number of turns in which the core is unsaturated in all operating conditions .
Es ist von Vorteil, daß der Kern als ein gestreckter Kern ausgebildet ist, weil somit auf einfache und kostengünstige Weise aufgrund der großen Scherung des Ferritkerns die Sekundärinduktivität des Hochspannungs-Zündübertragers nahezu stromunabhängig dimensioniert werden kann und somit Ungleichmäßigkeiten in dem Betriebsstrom, die z. B. die Regelung einer konstanten Lichtleistung erschweren, als auch sprunghafte Änderungen der großen Anlaufströme sicher und zuverlässig vermieden werden können, da der Kern nicht in die Sättigung gehen kann. Zudem ergibt sich der Vorteil, daß der Hochspannungs-Zündübertrager möglichst geringe Abmessungen aufweisen kann und ein durchschlagsicherer hochspannungsgerechter Wicklungsaufbau bei einem möglichst hohen Wirkungsgrad erreicht wird.It is advantageous that the core is designed as an elongated core, because thus the secondary inductance of the high-voltage ignition transformer can be dimensioned almost independently of current and thus irregularities in the operating current, which, for. B. complicate the control of a constant light output, as well as sudden changes in the large starting currents can be safely and reliably avoided, since the core can not go into saturation. In addition, there is the advantage that the high-voltage ignition transformer can have the smallest possible dimensions and a breakdown-proof high-voltage-compatible winding structure is achieved with the highest possible efficiency.
In diesem Zusammenhang ist es von Vorteil, daß der gestreckte Kern aus einem weichmagnetischen Ferrit-Material besteht, wodurch die Abmessungen besonders gering sein können, und bei einem hochspannungsgerechten Wicklungsaufbau einen möglichst großer Wirkungsgrad für die Hochspannungs-Zündübertrager erreicht werden kann.In this context, it is advantageous that the stretched core consists of a soft magnetic ferrite material, whereby the dimensions can be particularly small, and the highest possible efficiency for the high-voltage ignition transformer can be achieved with a high-voltage-compatible winding structure.
Die vorab genannten Vorteile werden insbesondere dann erreicht, wenn der Kern eine Querschnittsfläche und die Sekundärwicklung eine Windungszahl aufweist, bei der bei allen Betriebsbedingungen der Kern ungesättigt ist.The advantages mentioned above are achieved in particular if the core has a cross-sectional area and the secondary winding has a number of turns in which the core is unsaturated in all operating conditions.
Dadurch, daß der Kern aus einem hochohmigen weichmagnetischen Ferrit-Material besteht, ergibt sich der Vorteil, daß die Wirbelstromverluste in dem Ferritkern möglichst klein gehalten werden können.The fact that the core consists of a high-resistance soft magnetic ferrite material results in the advantage that the eddy current losses in the ferrite core can be kept as small as possible.
Es ist von Vorteil, daß die Primärwicklung auf die Sekundärwicklung aufgewickelt ist, weil hierdurch die Primärwicklung die Sekundärwicklung vollständig umschließt und sich somit eine bestmögliche magnetische Verkopplung der Primärwicklung mit der Sekundärwicklung ergibt, die einen hohen Wirkungsgrad zur Folge hat und zum anderen den Vorteil, daß das niedrigere Potential bei dem Betrieb des Hochspannungs-Zündübertragers an der Außenseite des Hochspannungs-Zündübertragers vorliegt, wodurch sich eine vereinfachte bessere Isolation und damit höhere Sicherheit gegen überschläge ergibt.It is advantageous that the primary winding is wound on the secondary winding, because in this way the primary winding completely encloses the secondary winding and thus there is the best possible magnetic coupling of the primary winding with the secondary winding, which results in high efficiency and on the other hand the advantage that the lower potential is present when the high-voltage ignition transmitter is operated on the outside of the high-voltage ignition transmitter, which results in simplified, better insulation and thus greater security against flashovers.
In diesem Zusammenhang ist es besonders vorteilhaft, daß die Primärwicklung und die Sekundärwicklung jeweils eine Windung pro Lage der Folie aufweisen, weil somit die sehr hohe Windungsspannung gleichzeitig die Lagenspannung ist, die jeweils durch die Isolierfolie isoliert wird und die Primärwicklung selbst bei minimaler Windungszahl automatisch gleichmäßig über die gesamte Wicklungsbreite verteilt ist, so daß sich eine optimale Kopplung zwischen der Primärwicklung und der Sekundärwicklung ergibt und zudem partielle Sättigungen des Ferritkerns vermieden werden.In this context, it is particularly advantageous that the primary winding and the secondary winding each have one turn per layer of the film, because thus the very high winding voltage is at the same time the layer voltage, which is isolated by the insulating film and the Primary winding is automatically evenly distributed over the entire winding width, even with a minimum number of turns, so that there is an optimal coupling between the primary winding and the secondary winding and, in addition, partial saturations of the ferrite core are avoided.
Es ist von Vorteil, daß die zwischen den einzelnen Lagen der Primärwicklung und der Sekundärwicklung angeordnete Isolierfolie breiter ist als die Folie der Primärwicklung und der Sekundärwicklung, weil sich somit bei einem einfachen und kostengünstigen Aufbau eine besonders hohe Sicherheit gegen Überschläge ergibt.It is advantageous that the insulating film arranged between the individual layers of the primary winding and the secondary winding is wider than the film of the primary winding and the secondary winding, because this results in a particularly high security against flashovers with a simple and inexpensive construction.
Zwischen der Sekundärwicklung und dem Kern ist ein Spulenkörper aus isolierendem Material angeordnet, weil das direkte Aufwickeln auf den Kern aufwendig und schwierig ist.A coil former made of insulating material is arranged between the secondary winding and the core, because the direct winding onto the core is complex and difficult.
Es ist von Vorteil, daß der Kern ein Stabkern ist, wodurch sich eine besonders einfache und kostengünstige Ausführungsform ergibt, bei der keine Sättigung des weichmagnetischen Ferrit-Kerns auftritt.It is advantageous that the core is a rod core, which results in a particularly simple and inexpensive embodiment in which there is no saturation of the soft magnetic ferrite core.
Die gleichen Vorteile ergeben sich bei einer zudem vorteilhaften Form für das Aufbringen der Folien als Primärwicklung, wenn der Kern zylinderförmig ausgebildet ist.The same advantages result in an advantageous form for the application of the foils as the primary winding if the core is cylindrical.
Dadurch, daß der Kern die Wicklungen abstützende Schultern aufweist, ergibt sich der Vorteil, daß die Feldlinien nicht so weit aus den Endbereichen des gestreckten weichmagnetischen Ferrit-Kerns austreten wie bei einem gestreckten Kern, der solche Schultern nicht aufweist, wodurch Wirbelstromverluste in angrenzenden Metallteilen, wie z. B. einem Gehäuse, reduziert werden.The fact that the core has the shoulders supporting the windings results in the advantage that the field lines do not emerge as far from the end regions of the stretched soft magnetic ferrite core as in the case of a stretched core which does not have such shoulders, as a result of which eddy current losses in adjacent metal parts such as B. a housing can be reduced.
Die gleichen Vorteile ergeben sich, wenn der Kern ein Rollenkern ist.The same advantages result when the core is a roll core.
Es ist von Vorteil, daß der Kern die Spulenkörper, die Primärwicklung und die Sekundärwicklung in einer isolierenden Vergußmasse vergossen sind, weil somit die Gefahr von Überschlägen auf ein Minimum reduziert wird und die Sicherheit und die Lebensdauer erhöht werden.It is advantageous that the core, the bobbin, the primary winding and the secondary winding are cast in an insulating casting compound, because the risk of flashovers is thus reduced to a minimum and the safety and the service life are increased.
Dadurch, daß der Kern, der Spulenkörper, die Primärwicklung und die Sekundärwicklung in einem Gehäuse angeordnet und mit diesem vergossen sind, ergibt sich der Vorteil, daß der Hochspannungs-Zündübertrager ein besonders kompaktes, hochspannungsfestes, leicht zu montierendes Bauteil ist.The fact that the core, the bobbin, the primary winding and the secondary winding are arranged in a housing and potted with this, there is the advantage that the high-voltage ignition transformer is a particularly compact, high-voltage-resistant, easy-to-assemble component.

Figur 1 zeigt einen Längsschnitt durch einen erfindungsgemäßen Hochspannungs-Zündübertrager. Der gestreckte Kern (K) aus weichmagnetischem Ferrit-Material, der hier beispielhaft als Stabkern ausgebildet ist, ist von einem Spulenkörper (U) umgeben, der aus isolierendem Material besteht. Auf den Spulenkörper (U) ist die Sekundärwicklung (S) des Hochspannungs-Zündübertragers, die aus einer leitenden Folie (F) und einer Isolierfolie (I) besteht, aufgewickelt. Auf die Sekundärwicklung (S) ist die Primärwicklung (P) aufgewickelt, die ebenfalls aus einer leitenden Folie (F) und einer Isolierfolie (I) besteht. Die Primärwicklung (P) und die Sekundärwicklung (S) sind zum elektrischen Anschluß hier beispielhaft mit elektrischen Anschlußelementen (A) verbunden. Die Kontaktierung der elektrisch leitenden Folie (F) mit den elektrischen Anschlußelementen (A) ist hier nicht gezeigt und kann z. B. über in die Folien eingeschlagene oder mit diesen verschweißte Anschlüsse erfolgen.FIG. 1 shows a longitudinal section through a high-voltage ignition transformer according to the invention. The stretched core (K) made of soft magnetic ferrite material, which is designed here, for example, as a rod core, is surrounded by a coil former (U), which consists of insulating material. The secondary winding (S) of the high-voltage ignition transformer, which consists of a conductive film (F) and an insulating film (I), is wound onto the coil former (U). The primary winding (P), which also consists of a conductive film (F) and an insulating film (I), is wound onto the secondary winding (S). The primary winding (P) and the secondary winding (S) are connected here by way of example to electrical connection elements (A) for the electrical connection. The contacting of the electrically conductive film (F) with the electrical connection elements (A) is not shown here and can, for. B. are made in the foils or welded to these connections.
Der Kern (K), der Spulenkörper (U), die Primärwicklung (P) und die Sekundärwicklung (S) sind hier beispielhaft zur Verbesserung der überschlagfestigkeit in einer isolierenden Vergußmasse (V) vergossen. Zudem sind der Kern (K), der Spulenkörper (U), die Primärwicklung (P) und die Sekundärwicklung (S) hier beispielhaft in einem Gehäuse (G) angeordnet und mit diesem vergossen. Bei einem anderen Ausführungsbeispiel kann der Hochspannungs-Zündübertrager auch mit anderen Bauteilen eines Zündgeräts einer Hochdruck-Gasentladungslampe in einer isolierenden Vergußmasse (V) vergossen sein.The core (K), the coil former (U), the primary winding (P) and the secondary winding (S) are cast here in an insulating potting compound (V) as an example to improve the flashover resistance. In addition, the core (K), the coil former (U), the primary winding (P) and the secondary winding (S) are arranged here by way of example in a housing (G) and potted with this. In another exemplary embodiment, the high-voltage ignition transformer can also be cast in an insulating casting compound (V) with other components of an ignition device of a high-pressure gas discharge lamp.
Figur 2 zeigt einen Querschnitt durch einen erfindungsgemäßen Hochspannungs-Zündübertrager. Wie schon unter Figur 1 beschrieben, besteht der Hochspannungs-Zündübertrager hier beispielhaft aus einem Kern (K), einem Spulenkörper (U), einer Primärwicklung (P) und einer Sekundärwicklung (S) in Folientechnik, die mit ihren elektrischen Anschlußelementen (A), von denen hier zwei beispielhaft gezeigt sind, mittels einer isolierenden Vergußmasse (V) in einem Gehäuse (G) vergossen sind.FIG. 2 shows a cross section through a high-voltage ignition transformer according to the invention. As already described under FIG. 1, the high-voltage ignition transformer here consists, for example, of a core (K), a coil former (U), a primary winding (P) and a secondary winding (S) using film technology, which with their electrical connection elements (A), Two of which are shown here by way of example, are cast in an enclosure (G) by means of an insulating casting compound (V).
Die in Figur 1 und Figur 2 gezeigte Ausführungsform weist besonders geringe Abmessungen auf und ist bei einfacher und kostengünstiger Ausführung besonders hochspannungsfest. Bei Verwendung eines hier beispielhaft gezeigten zylinderförmigen Stabkerns (K) beträgt die Länge des Gehäuses beispielhaft etwa 2 bis 3 cm und beträgt die Breite und Höhe des Gehäuses beispielhaft etwa 1 bis 2 cm. Bei anderen Ausführungsbeispielen können diese Maße auch größer oder kleiner sein. Bei dem hier gezeigten Hochspannungs-Zündübertrager zum Zünden und Betreiben von Hochdruck-Gasentladungslampen in Kraftfahrzeugen, der aus einigen wenigen 100 Volt Zündspannungen bis zu 20 KV erzeugen muß, weist die innen auf den Spulenkörper (U) aufgebrachte Sekundärwicklung (S) beispielhaft etwa 100 Windungen auf und weist die auf die Sekundärwicklung (S) aufgebrachte Primärwicklung (P) beispielhaft etwa 4 Windungen auf. Zur guten magnetischen Verkopplung, wodurch ein hoher Wirkungsgrad erreicht wird, wird bei der Wicklung der Folie (F) eine Windung pro Lage aufgebracht. Aufgrund der extrem dünnen Folie (F), die für die Wicklungen (P, S) Verwendung findet, und der geringen Anzahl der Windungen der Primärwicklung (P) ist die Primärwicklung (P) in allen Figuren nicht gesondert dargestellt.The embodiment shown in Figure 1 and Figure 2 has particularly small dimensions and is particularly high voltage resistant with a simple and inexpensive design. When using a cylindrical rod core (K) shown here by way of example, the length of the housing is, for example, approximately 2 to 3 cm and the width and height of the housing is, for example, approximately 1 to 2 cm. In other exemplary embodiments, these dimensions can also be larger or smaller. In the high-voltage ignition transformer shown here for igniting and operating high-pressure gas discharge lamps in motor vehicles, which has to generate up to 20 KV from a few 100 volt ignition voltages, the secondary winding (S) applied to the inside of the coil former (U) has, for example, about 100 turns and has the primary winding (P) applied to the secondary winding (S), for example, about 4 turns. For good magnetic coupling, which achieves a high degree of efficiency, one turn per layer is applied when winding the film (F). Because of the extremely thin film (F) used for the windings (P, S) and the small number of turns of the primary winding (P), the primary winding (P) is not shown separately in all figures.
Figur 3 zeigt die Einzelheit (H) entsprechend Figur 1. Der Kern (K) besteht hier aus einem weichmagnetischen Ferrit-Material. Um Wirbelstromverluste möglichst gering zu halten, wird hier beispielhaft ein Material verwendet, das möglichst hochohmig ist. Der Spulenkörper (U) umgibt den Kern (K) derart, daß der Kern (K) und der Spulenkörper (U) fest aneinander anliegen. Um eine möglichst hohe Packungsdichte und geringe Abmessungen zu erreichen, ist die Sekundärwicklung (S) fest auf dem Spulenkörper (U) aufgewickelt. Die in Figur 3 nicht gezeigte Primärwicklung (P) ist fest auf die Sekundärwicklung (S) aufgewickelt. Der Kern (K) kann bei einem anderen Ausführungsbeispiel die Wicklungen (P, S) abstützende Schultern aufweisen, die die Feldlinien an den freien Enden des Kerns (K) nicht soweit austreten lassen wie bei einem gestreckten Kern (K) ohne derartige Schultern. Eine besonders günstige Ausführungsform des Kerns (K) ergibt sich bei Verwendung eines Rollenkerns. Ausführungen dieser Art sind in den Figuren nicht gezeigt.Figure 3 shows the detail (H) corresponding to Figure 1. The core (K) consists of a soft magnetic ferrite material. In order to keep eddy current losses as low as possible, a material that is as high-resistance as possible is used here as an example. The coil former (U) surrounds the core (K) in such a way that the core (K) and the coil former (U) lie firmly against one another. In order to achieve the highest possible packing density and small dimensions, the secondary winding (S) is firmly wound on the bobbin (U). The primary winding (P), not shown in FIG. 3, is wound tightly onto the secondary winding (S). In another exemplary embodiment, the core (K) can have the shoulders (P, S) which support the windings Do not allow field lines to emerge at the free ends of the core (K) as far as with a straight core (K) without such shoulders. A particularly favorable embodiment of the core (K) results when using a roller core. Designs of this type are not shown in the figures.
Figur 4 zeigt den Wicklungsaufbau sowohl der Primärwicklung (P) als auch der Sekundärwicklung (S). Jede Lage der Primärwicklung (P) und der Sekundärwicklung (S) besteht aus einer elektrisch leitenden Folie (F), die gegenüber den anderen Lagen durch eine Isolierfolie (I) isoliert ist. Wie aus Figur 4 erkennbar, beträgt hier die Breite der Folie (F) beispielhaft etwa 2/3 der Breite der Isolierfolie (I), um mit großer Zuverlässigkeit Überschläge zu vermeiden. Die Breite der Isolierfolie entspricht bei dem hier gezeigten Ausführungsbeispiel der Länge des zylinderförmigen Kerns (K), um Überschläge bestmöglich zu vermeiden. Bei der Wicklung der Primärwicklung (P) und der Sekundärwicklung (S) ergibt sich somit jeweils eine Windung pro Lage, was eine sehr gute magnetische Verkopplung unter der Vermeidung von Sättigungszonen des Kerns (K) gewährleistet, auch wenn die Primärwicklung (P) nur wenige Windungen aufweist. Die Isolierfolie (I) besteht hier beispielhaft aus einem Kunststoffmaterial und weist beispielhaft etwa eine Dicke von 15µm auf. Die Folie (F), aus der die Primärwicklung (P) und die Sekundärwicklung (S) besteht, kann beispielhaft aus Kupfer oder Aluminium bestehen und beispielhaft eine Dicke von etwa 10µm aufweisen. Je nach Anwendungsfall und den Erfordernissen können diese Maße größer oder kleiner sein.Figure 4 shows the winding structure of both the primary winding (P) and the secondary winding (S). Each layer of the primary winding (P) and the secondary winding (S) consists of an electrically conductive film (F), which is insulated from the other layers by an insulating film (I). As can be seen from FIG. 4, the width of the film (F) is, for example, approximately 2/3 of the width of the insulating film (I), in order to avoid rollovers with great reliability. In the exemplary embodiment shown here, the width of the insulating film corresponds to the length of the cylindrical core (K) in order to avoid rollovers as best as possible. With the winding of the primary winding (P) and the secondary winding (S) there is one turn per layer, which ensures a very good magnetic coupling while avoiding saturation zones of the core (K), even if the primary winding (P) only a few Has turns. The insulating film (I) consists here, for example, of a plastic material and has, for example, a thickness of approximately 15 μm. The foil (F), from which the primary winding (P) and the secondary winding (S) are made, can be made of copper or aluminum, for example, and can have a thickness of about 10 µm, for example. Depending on the application and the requirements, these dimensions can be larger or smaller.
