Kapanadze Cousin - DALLY FREE ENERGY

[verpies]

Dally have made another Solid-State-OU-Generator.

Does version 2 work as well as version 1?

Further to my post 224, the KD226G diode is not packaged to take a heat sink.

Hi guys!

Posted photos of "green transformers". This is what I found in my pantry. This is a military standard for special transformers, of which there are a huge number of specifications. Produced on the U-shaped cores and toroids. I disassembled the transformer, such as the Dally.
The core is made of an alloy of "alsifer" (aluminium, silicon, iron) or mu - permalloy to avoid saturation. Cores are designed to operate at low frequencies up to 10 kHz, where the use of ferrites impossible.
Dally just picked suitable transformer for his DC-DC converter.
To make such a transformer  I can recommend the rings
made out of u-permalloy.

You may use bigger ring up to 2 cm outer diameter.  Ðœ6000НМ or better.

I do not agree with Sergei, this fundamental error which began to make in our forums. In this scheme, the core must  to work in saturation mode, otherwise the effect DSRDs diode is not going to happen.
It is necessary to use small-diameter ring, as shown in basic scheme, it is 7 mm outer diameter.
In the scheme, sloping line indicates on the  transformer in  saturation mode.
The larger the size of the ring, the more difficult to enter it into saturation.

Ferrite is going hot so must be sealed or glued on KT926 radiator.

Yes, the ring will heat up, it will need to be glued on the radiator.

Excellent thanks. Now we have last bit of the jigsaw.
