Definitions

  • the invention relates to an electrical transformer at least one core, in particular made of ferrite, with at least one primary winding and with at least one Secondary winding.
  • a motor vehicle becomes an electrical one Transformer required with the smallest possible construction volume is inexpensive to manufacture. It is said to have high performance be operable and have a high efficiency. The Transformer is said to be used in modern motor vehicles occurring high currents work and cool easily his.
  • the at least one Core is arranged between electrical conductors, which from a substrate, in particular a printed circuit board, stand away, and that the ends of the standing ladder under Formation of the transformer windings electrically connected are.
  • the conductors can be soldered onto the substrates, welded on or by simple plug-in or Press connections to be fastened in the substrates.
  • the transformer according to the invention can on a commercially available circuit board, which as a substrate serves to be executed.
  • the further substrate on that facing the first substrate Side tapered holes for receiving and centering the Conductor ends when the arrangement is mechanically plugged together having. This avoids errors in the automated Attach the further substrate due to bent or not exactly perpendicular from the first substrate Ladder.
  • the at least one core is a circular ring that the electrical conductor the core inside and outside shell-like surround and that the conductors to the transformer windings are connected. It can be provided that the electrical conductor as bowl-shaped the core shape adapted sheet metal strips are executed. So the core can almost completely with even a few windings Surrounded by conductor material.
  • the connecting conductor tracks can be made correspondingly wide on the substrates be so that the core is also complete on the deck sides is surrounded by the transformer windings, whereby result in low leakage inductances.
  • the substrate made of copper sheet welded onto heat-conducting ceramic (Direct copper bonding). Because of the very good Thermal conduction of this material is high performance of the Transformer. It can be used to cool the Transformer and the power circuits surrounding it be provided that the substrate on a heat sink is glued on.
  • a Circuit arrangement for operating the transformer is arranged. Furthermore, to further reduce the Size and manufacturing costs should be provided that at least one of the substrates used in multiple layers, in particular, can be equipped on both sides.
  • FIG. 1 shows one between two substrates 1 and 2 arranged annular ferrite core 3, which is between the Substrates 1 and 2 contacted the Surround transformer sheets forming conductor plates 4 is.
  • the conductor plates 4 are connected by conductor tracks 5 to the Substrates 1 and 2 to the transformer windings interconnected.
  • Next to the transformer itself are still further components 6 for controlling the transformer on the substrates 1 and 2. This is to dissipate heat lower 2 of the substrates glued to a cooling element 7.
  • Fig. 2 shows the same transformer schematically in Top view. The illustration is enlarged compared to FIG. 1. The current direction in the conductor plates is with dot and Cross symbols indicated. On the right is the primary and the secondary winding on the left.
  • FIG. 3 shows how a number of toroidal cores 32, 33, 34 to form a single transformer can be used. This way too very flat cores to a powerful transformer put together.
