Definitions

  • the present invention relates to electromagnetic power windings and transformers comprising such windings generally used in electronic power circuits and in particular in electrical supplies of electronic circuits.
  • the patent D2 describes windings formed of turns comprising "two tongues forming an outward protrusion of the stack of turns constituting the winding, these tabs making it possible to easily make the electrical connection in parallel or in series of the turns" (page 3 lines 14-18 of document D2).
  • the D1 patent describes an arrangement of turns comprising such tabs arranged on a support so as to better evacuate the heat released in circuits comprising these turns.
  • the winding comprises a support on which rests a set of conductive, independent, contiguous turns, covered with an insulating sheath and inside which a magnetic circuit can be introduced and on which are printed conductive tracks to achieve electrical continuity between each turn.
  • These conductive turns are bent on themselves towards the inside or the outside, depending on whether it is a self-inductance or a transformer, so as to form a box in which the circuit can be introduced.
  • magnetic for example a ferrite.
  • each of these conductive turns are located opposite one another and are produced so as to be able to rest on the support comprising an insulating and thermal conductive substrate; these ends also provide electrical continuity and conduction thermal with the insulating substrate to dissipate the heat transmitted by the turns during the passage of a current inside the winding.
  • the object of the invention is to remedy these drawbacks by modifying the shape of the turns and by proposing a particular interlacing of these turns.
  • the present invention relates to an electromagnetic power winding comprising conductive turns, each turn being independent and having two ends, a first and a second, the turns being aligned along the same axis, the winding consisting of a first set of turns. forming a primary winding and a second set of turns forming a secondary winding thus constituting a transformer, the electrical continuity between the turns of each set and the evacuation of the heat transmitted by the turns being ensured by the fact that each of the ends of each turn rests on a conductive track printed on an electrically insulating and thermally conductive substrate, characterized in that each turn is coated with an electrical insulating deposit to isolate it from the other turns, the turns constituting the primary and those constituting the secondary are alternated, the first and second ex end of each turn are placed side by side and arranged on the same side with respect to a median plane perpendicular to the plane of the turn and distant from it, the turns constituting the primary being pivoted by 180 ° relative to the turns constituting the secondary so that the ends of the turns
  • FIG. 1 there is shown a first application of the winding according to the invention. It concerns a first application of this winding as a transformer.
  • the winding comprises two sets of turns P1 to P n and S1 to S n positioned on the same axis, a magnetic circuit and a support.
  • the coil is constituted, on the one hand, by a first set of conductive turns P1 to P n connected in series by the support and on the other hand, by a second set of conductive turns S1 to S n connected in parallel by the support .
  • the winding behaves like a step-down or step-up transformer, the primary being for example constituted by the turns P1 to P n and the secondary by the turns S1 to S n .
  • These turns P1 to P n and S1 to S n are not obtained in a conventional manner by winding a single conductive wire around a core. They are produced by a set of conductors P1 to P n and S1 to S n all identical.
  • a turn 1 is shown in Figure 2. Each of these turns is curved on itself, so as to form, for example, a rectangle inside which can be introduced a magnetic circuit.
  • each of turns 3 and 4 are placed side by side and are made so that they can rest on the support to establish thermal and electrical contact.
  • the ends of each turn 3 and 4 are connected to the support 2 of Figure 1 so as to allow an electrical connection, for example it is a weld.
  • the shape and arrangement of the turns P1 to P n and S1 to S n have been designed so as to obtain a maximum insulation voltage by moving the ends of the primary and secondary turns away.
  • the assembly of the turns P1 to P n and S1 to S n allowing the constitution of the coil of the electromagnetic power winding, is carried out in the following manner: a turn is previously taken up with a deposit of electrical insulator, as shown in Figure 2, we juxtapose a second turn that we will have rotated 180 ° so that the ends of the second turn are opposite the ends of the first turn, we then take a third turn positioned behind the second but whose ends are found opposite the ends of the first turn. These turns are alternated until the winding is formed.
  • the support 2 comprises a substrate or printed circuit 6 and a cooling system, for example a radiator 7.
  • the substrate or printed circuit 6 is placed on the radiator and is integral therewith, it is an electrical insulating substrate, good thermal conductor.
  • a set of conductive tracks F1 to F n and G1 to G2 is printed or screen printed on the substrate 6 so that, when the coil is fixed on this substrate 6 and supplied, the current can flow through it. Indeed, at a given instant, the current arrives on the track F1, follows the first turn P1, then successively traverses the second track F2 and the turn P2 until the turn P n and the track F n .
  • the winding comprising a magnetic circuit, a current also passes through each of the turns S1 to S n ; these turns being mounted in parallel thanks to the conductors G1 and G2, one recovers on the conductors a current depending on the chosen transformation ratio.
  • the heat released by each turn S1 to S n and P1 to P n and by the magnetic circuit is transmitted to the substrate 6 longitudinally along these turns.
  • the substrate 6 is designed to allow the electrical connection between the turns and to advantageously capture the heat given off by the winding and transmit it to the radiator 7.
  • the electrical conductor that constitutes the turn also serves as a thermal conductor.
  • the substrate 6 is in this particular embodiment an alumina plate a few hundred microns thick.
  • the radiator 7 is known per se, it makes it possible to dissipate the heat released and thus to allow permanent cooling of the winding.
  • the magnetic circuit 8, 9 consists in our particular embodiment, of two boxes able to be introduced inside the winding and to wrap the turns when they are joined in order to capture the maximum flux.
  • FIG. 3 represents a sectional view of the circuit according to the invention. It makes it possible to show the movement of the heat flow over a turn via the arrows, represented in this figure, which indicate the movement of the flow during the passage of a current.
  • the present invention applies to any support for any surface mounting.
