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.
