In the Winding section you will be able to fully customize the winding arrengement of your design. Also, you can run a simulation and visualize the results from it.




Standard image-1647511753730.png

From this tab you can define the standard used to denote wires size: International (mm) or American (AWG).


Winding Arrangement image-1647511850251.png

This drop-down menu will show you the 4 basic configurations available for defining the winding arrangement: PS, PSP, PSPS and Two Chamber.

It is possible to select a different configuration using the Customize feature.

Once a new winding arrangement is selected, it is necessary to run the simulation in order to apply the changes.


Wires image-1647512000307.png

The wires panel allows you to modify all the parameters referred to the wires. At the top of the panel image-1647512062606.png, select the winding tab to see the wire parameters and simulation results of the corresponding winding.

Parameters in the Wire Menu:

  •  Group with: Allows you to group multiple windings.

  • Wire type: Choose between Litz, Round, Foil and Rectangular (Inductors only)

  • Turns

  • Width (Foil and Rectangular)

  • Thickness (Foil wire)

  • Height (Rectangular wire)

  • Nº of strands (Litz wire)

  • Strand diameter (Round and Litz)

  • Grade (Round and Litz)

  • Serving (Litz wire): Choose to have unserved or single served wire

  • Nº of insulation layers (Round and Litz): You can set none, one (SIW), two (DIW) or three (TIW) insulation layers

  • Insulation type (Round wire): Enamel or Plastic

  • Margin Tape: Added at top and bottom of the layers.

  • Nº of Parallels

  • Nº of Layers

Every time you make a change in any of the wires parameters, it is necessary to run the simulation in order to update results and representation of the new winding configuration.

Textile serving in the litz wire act as an optional layer of added mechanical protection for the overall conductor. Serves are particularly effective at protecting the enamel layer on the individual strands of the conductor from abrasion during further processing. On the other hand, it reduces the wire flexibility.


Grouped Windings

Use the Group with tab in the Wires menu to group multiple windings. Basic grouping allows you to have a configuration in which different windings are wounded in the same layer.


The image shows the representation of a winding arrangement with two secondary windings grouped.

In order to successfully set grouped windings:

  • Windings must have the same wire: dimensions, number of parallels and insulation.
  • Windings must have the same number of layers.
  • Windings must have the same margin tape.

WARNING: If you try to group windings that don't satisfy the previous requirements, the parameters from the grouped windings will be automatically modified to match with the configuration of the first grouped winding.

Nº of turns is the only parameter from the Wire menu that can be different within the grouped windings. If the number of turns is the same for all the windings, they will be wounded all together, just like the image below.


Simulation Results image-1647513080629.png

In this section you will find a detailed breakdown of specifications and results from the simulations. These results are referred to the selected winding.

Results provided in this section:

  • Wire Dimensions: Width, height and length.

  • Current density

  • Skin depth

  • Breakdown of the losses: Due to Fringing, skin and proximity effects.

  • Total losses.

  • DC Resistance.

  • DC losses.

  • Leakage Inductance (Secondary windings): This result is the Llk referred to the primary


General results image-1647513180657.png

In this section you can find more general results:

  • Filling factor: Percentage of area of the window which is occupied by the winding.

  • AC Resistance

  • Total winding losses.


Representation of the windings image-1647513255983.png

This section provides visual information about the winding distribution within the window. It will allow you to check if the windings fit in the bobbin as well. Other than windings, margin tape, gap and isolation layers are represented too.

If the winding configuration that is loaded doesn't fit in the bobbin, a warning message will appear once you run the simulation.

Suggest Wire image-1647513642847.png

When clicking in the Suggest wire  button, the platform will provide a new solution for the windings, modifying and loading the new parameters in Wires menu, and running the simulation at the same time. This suggestion will provide a commercially available and manufacturable solution. Again, you can use these suggestions as starting points for your winding arrangement.

The wire suggestion will take into account the nº of turns, margin tape (if added) and winding arrangement selection (PS, PSP, PSPS or Two Chamber).

Suggest Wire feature does not support Grouped windings or Custom Winding features


Run image-1647513826449.png

Every time you make a change in the winding section, make sure you click the RUN button in order to update both the results and the windings representation.

If you click Suggest Wire you won't need to click RUN to simulate the new windings. It will be automatically done.
