Group member Alexander Bordodynov (Александр Бордодынов </g/LTspice/profile/3025720>) has modelled a number of non-linear cores, and has a core library. I have no

LTspice doesn't have any built-in models and processes for modelling magnetic circuits in the way you need. It would be possible to write the necessary files, but it would be a major project. -- This

Hi , Thanks for the reply But I want to model it in SPICE model editor and use it in my circuit ,

Routinely thanking the Internet spirits for the wayback machine, which is incredibly useful -- until it isn't. Donald.

I think you might try the FEMM/g/femm/ (Finite Element Magnetic Modelling) /g/femm/ group for this question. That group is dedicated to such issues. Transformers in

My remarks refer specifically to EDN's Design Ideas. This is an extract from the official: Design Ideas Submission Guide

Nice to know it! Thank you so much!

Thank you so much for your help and support, Andy!

Yes, and I posted that I understood the error. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

@Andy See mosfets in weak inversion regions ( /g/LTspice/photo/302220/3915724?p=Created%2C%2C%2C20%2C2%2C0%2C0 ) Did I measure wrongly or had the wrong circuit connections compared to

Have you corrected the position of the OUT node?

Hi , I am trying to model the Ep10 core with T38 material from TDK micronas I have modelled the core but I am not sure whether it is correct or not ? How do I check my model ? Also it would be good if

I am just noting that the required op-amp model file (LM4562_NS.sub) is missing from your uploaded ZIP. UniversalOpamp2 works fine in its place. Andy ( #DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2 )

Perhaps I remember incorrectly.? But I thought all circuit diagrams in EDN articles were re-drawn by EDN's editors.? I do not recall seeing author-drawn schematics in their "Design Ideas" or

From Google, I found at least 3 versions of the 1232-A product manual.? All had scanned schematics, but not all were the same.? One of the downloadable PDFs (pearl-hifi.com) had several copies of

To which, John Woodgate replied: "General Radio" became "GenRad" and might be better known by that name.? Years ago, GenRad was bought out by JET Labs, who re-branded GenRad's products, and the name

I gave not seen RAP's original article. I looked the circuit up using John Woodgate's citation: "Analog Circuits: World Class Designs", edited by Bob Pease, page 236, "Multiple Feedback Bandpass

Thank you very much.

I haven't seen Pease's original diagram. I was going strictly by the EDN article. This is a recent article, and I know from experience that the EDN editors encourage writers to supply their own
