Yea Steve, the issue was with the potential for unequal load sharing between the two windings if they are not nearly identical in terms of impedance. This issue is raised primarily where two transfor
No, Tom is correct. Flux density is a function voltage, not current. If you look up the voltage equation for transformers you'll see that current is not involved. Ampere-turns is what determines the
Rather than do all this guessing and wondering and trying to re-invent the wheel, why don't you pose your questions and theories to the folks at CDE or HEC or ATC: they're the ones that stamp the cur
Xu, Go to http://www.freetradezone.com You'll have to register, there is no charge for registration. You will then be able to search and download all kinds of data sheets. I am usually able to find d
If there's anyone on the list that has a subscription to the Freetradezone website (formerly Part Miner), I need to know either the substitute or sources, for the Mitsubishi M5201A chip. Any help app
Gents, I've added a new copy of the QEX Microwave Oven Transformer article to my website. The new one is in MS Word 6/95. The file is big (2.4M) but that's the way Word 97 converted/saved it. The Wor

Ian, You - of all people - do not need to apologize. The provocation was severe. Rich has become such a pain in the arse that I've finally filtered all his posts. If he ever has anything useful to sa

I remember this - it was done by a guy with a dutch last name. It was a 2 KVA supply, around 2 KV. It was the size of a shoe box and weighed 10 or 15 lbs. I believe it was included just one year in t
They work just fine if they have a secondary voltage that is usable for your project. There are several that have been in use in home brew amps up here in Ontario for years and years. I ran a 5 KVA u
Well this would work OK Jim if the core is made of E-I laminations. But so far I haven't had any pole pigs made from E-I's : they're all hypersil, strip wound cores. In many cases the cores (the cont
