Exporting Transformer Design Specification as Text

[Andrew Baker]

Posted on May 14, 2018 at 14:20

I've just used EDesignSuite to design a Flyback PSU based around a L6566B

As part of this, it has designed me a transformer, in around half a page of small, poorly formatted, dense, closely type text.

How do I export this text so as to send it off to be made? It does not seem to be possible to get it out in any useful form?

(Printed page is NOT 'useful' in this context)

Surely you do not expect me to slowly, tediously and laboriously re-type all this text, probably introducing expensive errors as I go?

Hello Andrew,

have you already tried to print the design report?

Opening the print view you can save it as PDF, otherwise you can copy the text and paste wherever you want.

Best regards,

Patrizia

The PDF is a graphic, which I cannot copy and paste from, I can't even select any text.

I tried selecting the text and copying pasting, I can select it, but when I paste I just get blank text, wherever I try and copy it from.

This is what I have just copied directly from the print view:

Transformer Design:

Core:

Type EE16S - Area Product 718 mm^4 - Orientation Vertical

Volume (Ve) 795 mm^3 - Cross-Sectional Area (Ae) 21.70 mm^2 - Bobbin Winding Area (Aw) 33.10 mm^2

Bobbin Average Turn Lenght 37.10 mm - Bobbin Centr. Leg Lenght 8.70 mm

Core Gap: 0.24 mm expected

Inductance factor (AL): 118 nH/N^2 expected

Primary: Turns 233 - Layers 18 - Paralleled wires 3

Wire: Manufacturer Wurth Elektronik - Part Number PN180 9283-0038 - Type Single

Number of strands 1 - Strand copper Ø 0.102 mm - Wire gross Ø 0.112 mm

Resistance per meter 2.2372 Ω/m

Secondary: Turns 9 - Layers 3 - Paralleled wires 3

Wire: Type Solid_G2 - Number of strands 1 - Strand copper Ø 0.425 mm

Wire gross Ø 0.488 mm - Resistance per meter 0.1244 Ω/m

Auxiliary: Turns 20

Wire: Type Solid_G2 - Number of strands 1 - Strand copper Ø 0.100 mm

Wire gross Ø 0.125 mm - Resistance per meter 2.3330 Ω/m

If you export the project as PDF, you can send directly that file to the transformer manufacturer, in the report there is all the necessary information.

Sorry it is not working on Linux, on Windows I can copy/paste without problems.

In next release we can expand the XML BOM you can save from the menu Save -> Export BOM as XML..., so that all the transformer information are given as text format.

Regards,

Patrizia

Hi Andrew,

just to inform you that in the new release a more complete report on the transformer design is exported when you save the project as XML file, that you can easily open as Excel table.

Best regards,

Patrizia

Thanks. When does the new release come out?

I've also been looking at some of the AC/DC isolated converters in eDesign.

Some of them allow you start a design, but are then incapable of

producing a design that meets the thermal ratings of the main chip, and

not by a bit, by a lot.

Some of them produce a design which is so lacking in information about

the output sense and opto as to be useless. They give so little

information or reference that you effectively need to start the design

yourself.

Are these problems known about and being addressed?

A.

The new release was published yesterday.

Do you mean designs with VIPer devices?

Hi Andrew,

I contacted you privately, I'm waiting your answer to redirect you to the right people in ST.
