Split Flux Transformer

[seaad]

Hi guys

I have only made some tests with a special H-brige, with extremely low idle current, driving a tuned high voltage transformer.
Mainly for testing my type I + II transformers  with a higher voltage input. The COP remained the same.
After that I have been busy with some house and garden projects.

hi seaad

very interesting results with your multicore!

i have an old multicore i made, inspired by the early Jensen design (which was a long time before Thane Heins BiTT)

as you can see from the photo below it has a common winding on the 2 narrower core loops, but i can remove the winding, separate those loops and rewind a primary on each to emulate your design (the core on the left is another, thicker toroid seen from sideways on)

i see that both you (and Jensen) have used AC drive but i'm more familiar with pulse operation, so i think i'll try that first


good luck with your tests, thanks

Hello seaad,  probably you heared about Heinrich Kunel and his "static magnetic generator",

he also wrote about "his device multi-fold cascading" up to MW-output range. Electrical  transformer coupling   how easy/ difficult in financial costs , especially if to include electrity output kind , DC or AC or pulsed AC, ? ----------------You ,seaad,are real experimenter, not only theorist :----------------
So my thinking and this related my question:---------------- transformer overload protection https://en.m.wikipedia.org/wiki/Inrush_current
each electrical device has for some pulse cycles inrush current and /or inrush voltage ,up to 100 times the nominal value,  so how are you/will you treating this short but to overcome barrier,which kind of " bridge/ glider" ? Inrush limiter ? For each cascade/couple  step a battery/ capacitor bank?

H. Kunel: Yes i have tried that with some gawky experiments. No luck so far.
But I also made many experiments with the split-trafo types without good results first, until suddenly! > 100%. (above my probes, scope uncertainty)
Much of the effect comes from the right core material type (I don't say mine are optimum here)
   See: http://www.energeticforum.com/307037-post642.html
And the core size ratio.

Inrush voltage is not an issue right now. The important thing now is to bring down the need of Kilo-Volt to the primaries.

I thank you for the answer, but the question was not specific the Kunel-device related( this only stated as example how to treat with great numbers and couplings with several " inrush phase" connections) )  it was and is a geral question:what is the physical and financial cheapest and easiest way to treat this "inrush phase" between couplings in electrical devices ?!f.e.: from a battery to - 1.connection and inrush step - an inverter to - 2. connection inrush step - a motor ......by consumer "no-load up to full load" conditioning!variable " soft drive" arrangement ?-------------------------------------------------------------
