Definitions

  • the required for the realization of the resonant converter series or Resonanzinduktterrorism are also housed within the arrangement and also the assembly and large-scale benefits of the generic technology are used.
  • the elevation 55 a relative to the elevation 29 a has a lower height (relative to the planar body portion of the core member), so that when facing each other pair of planar core elements of Fig. 1 the opposite elevations 29a touch each other end, insofar as a continuous ferrite leg is formed, while, due to the lower height, between the successive elevations 55a in the manner intended according to the invention an air gap remains.

Claims (10)

  1. Composant électronique à induction comportant une paire d'éléments de noyau plans ayant respectivement deux branches internes (29a, 55a) ainsi qu'au moins deux branches latérales (33a, 35a, 37a, 39a) respectivement associées de part et d'autre aux branches internes, auxquelles sont associés des systèmes d'enroulements plans destinés à réaliser un transformateur,
    dans lequel un premier des systèmes d'enroulements plans (TR2, TR4, TR5) est réalisé sous la forme d'un circuit série de deux enroulements partiels, parmi lesquels un premier enroulement partiel est réalisé au niveau des branches latérales (35a, 33a) sur un premier côté par rapport aux branches internes et un second enroulement partiel est réalisé au niveau des branches latérales (39a, 37a) sur un second côté par rapport aux branches internes,
    dans lequel les premier et second enroulements partiels présentent un nombre de spires et une direction de spires qui sont conçus de manière à ce qu'un flux magnétique résultant du premier système d'enroulements plan s'élève dans les branches internes, et soit notamment égal à 0, et à ce qu'un second des systèmes d'enroulements plans (TR1) soit réalisé de manière à ce qu'il soit magnétiquement découplé du premier système d'enroulements plan au niveau des branches internes, caractérisé en ce que les branches internes comportent des premières sections de noyau (29a) réalisées de manière à coopérer avec le second système d'enroulements plan (TR1), ainsi que des secondes sections de noyau (55a) prévues de manière espacée des premières sections de noyau et qui sont conçues pour coopérer avec un système d'enroulements plan (L1) supplémentaire formant un circuit série avec le second système d'enroulements plan,
    dans lequel les secondes sections de noyau sont configurées de manière à ce qu'elles forment un entrefer à effet magnétique pour le système d'enroulements plan supplémentaire.
  2. Composant selon la revendication 1, caractérisé en ce que les premières sections de noyau sont réalisées de manière à ce qu'elles forment un noyau sans entrefer pour le second système d'enroulements plan.
  3. Composant selon la revendication 1 ou 2, caractérisé en ce que les premier et second systèmes d'enroulements plans ainsi que le système d'enroulements plan supplémentaire sont réalisés sous la forme de pistes conductrices sur au moins une carte de circuit imprimé qui, pour coopérer magnétiquement avec les éléments de noyau, comporte des traversées et/ou des cavités (33-39, 29, 55) destinées aux sections des éléments de noyau formant les branches.
  4. Composant selon l'une quelconque des revendications 1 à 3, caractérisé en ce que l'un des éléments de noyau, réalisé de préférence en une seule pièce, présente une section de surface réalisée sous forme plane de manière à coopérer avec une carte de circuit imprimé portant au moins l'un des systèmes d'enroulements plans, section de surface à partir de laquelle s'étendent des protubérances (33a-39a, 29a, 55a) façonnées d'un seul tenant et formant les branches internes ainsi que les branches latérales.
  5. Composant selon la revendication 4, caractérisé en ce que l'élément de noyau forme une première protubérance (29a) pour réaliser la première section de noyau et forme une seconde protubérance (55a) pour réaliser la seconde section de noyau, dont la hauteur par rapport à la section de surface est réduite par rapport à la première protubérance.
  6. Composant selon l'une quelconque des revendications 3 à 5, caractérisé en ce que la paire d'éléments de noyau prévue des deux côtés de la carte de circuit imprimé s'engage dans au moins une traversée de la carte de circuit imprimé par des protubérances orientées les unes vers les autres.
  7. Composant selon l'une quelconque des revendications 3 à 6, caractérisé en ce que la carte de circuit imprimé forme une structure multicouche destinée à une pluralité de couches de pistes conductrices des systèmes d'enroulements plans et/ou fait partie d'un système en couches d'une pluralité de cartes de circuit imprimé.
  8. Composant selon l'une quelconque des revendications 1 à 7, caractérisé en ce que le composant électronique à induction est connecté sous la forme d'un convertisseur à résonnance ayant une pluralité de transformateurs réalisés par les systèmes d'enroulements plans, dans lequel le second système d'enroulements plan forme un transformateur côté entrée et le système d'enroulements plan supplémentaire forme une inductance de fuite associée côté primaire au transformateur côté entrée.
  9. Utilisation du composant électronique à induction selon l'une quelconque des revendications 1 à 8 dans un dispositif diviseur de courant, notamment destiné à faire fonctionner une pluralité de LED connectées en chaîne, en tant que charge, dispositif diviseur de courant dans lequel un courant produit côté secondaire par un premier transformateur côté entrée est divisé au moyen d'au moins un second transformateur en au moins deux dérivations de charge attaquées indépendamment l'une de l'autre.
  10. Utilisation selon la revendication 9, caractérisée en ce que le premier transformateur et l'au moins un second transformateur est réalisé sur la base d'une paire d'éléments de noyau du composant, dans lequel le second système d'enroulements plan forme le premier transformateur.
