Iron data and formulae
Gentlemen,
for those who are into winding their own transformers, here is a useful link (partly in english): http://www.waasner.de/uk/start.htm From there, click on the "Technic" link to find some sub-menues containing data, formulae and calculation instructions. Tom -- MS-DOS is the worst text adventure game I have ever played: Poor vocabulary, weak parser and boring storyline. |

Tom -- MS-DOS is the worst text adventure game I have ever played: Poor vocabulary, weak parser and boring storyline. Unfortunately, the above address would only attract those who like incomprehensible story lines and text adventures also found in MS-DOS I use the info in the more comprehensible text of RDH4, although even that damn book is confusing with its oersteds and gilberts, et all. Mark Harris and I are currently designing a computer program for output transformers. With minor mods, power trannies should also be possible. So far I have about 30 pages of book notes and 45 described calculations for a decent OPT outcome, and all should be readable by the not too technically trained person when we are done, and doable even if they find their tax return a problem to fill out correctly. We plan to sell the full program when we are finished. The designs will be for those who don't mind cool running, low losses, and appropriate bandwidth at low distortion, and quiet operation.

Hi Patrick,
Mark Harris and I are currently designing a computer program for output transformers. Great, but it is astounding how many programs are already out there for this task ... Yves mentioned his own (BTW the link seems to be broken) and here are other free ones: http://www.ecclab.com/start.php3?ID=10 and then scroll down a bit. Polski language? Nullski Problemski. Tom -- |

Do you mean that working in audio is not a real job ;) Somebody with a real job whinged to me about having to pay $8,000 in tax for a year. My reply was that I wished I earned that much ..... We gotta sell something. We think it will be worth it. Indeed. I'm totally naïve about business, but I want to credit you for the infos at your web site that helped me more than lot That website is getting stale, and its time for some revisions.....

Hi Patrick,
I cannot be astounded by what's out there, only by what isn't. Well put :-) Personally, I don?t have an idea how good or bad the mentioned programs are. Tom -- |

Most of them cannot relate their formula to anything I can recognise as science. I have never seen one that allows analysis of the finished product. I believe the formulas I have collected from a heck of a lot of reading of books, ( yeah, remember what books are folks? ), are more accurate than anytjhing I have seen on the Web. Anyway, I ain't worried. After having wound a lot of OPTs, and measuered them, I know the formulas I have actually work. Doing a Google on 'audio frequency transformer program' or 'output transformer program' brings up nothing much after I tried..... Getting a core size and turns is easy, but then you have to get the winding losses, leakage, capacitance and distortion all low, and that means good winding geometry. Patrick Turner. Tom -- |
