thanks man again

and utorrent is better

utorrent doesn't exist anymore. It was absorbed by bit torrent proper. The new Bit Torrent IS utorrent now. www.bittorrent.com.

Hi Marco,

Great Observation! I've been doing some research on those little white toroidal coils and, just as Spherics alluded to by the patent he posted, these cores are actually Saturable Reactor Switches. I found that these are used in the industry as a high-power, high voltage replacement for SS devices.

So lets say that you want to make a short, fast, really high voltage pulse? You pulse one of these cores, which saturates immediately at a given current value; suddenly after that, the inductance of the core drops to almost nothing which causes a large current surge and resulting spike on the output, just like if you were reverse biasing a diode until it broke down!

Here is an interesting paper that discusses exactly how it works. The information about the saturable core switches is on page 6

Now I'm just trying to see if I can find a source for these little cores.

FYI, the last two pieces of the Part 2 zip file have now been added to the MediaFire folder. you should be able to rejoin and view it after downloading them

http://www.mediafire.com/?sharekey=bcb5de0bd0f181ea8c9e7c56ba37815f5a52c02ec6da2cd7

I'll try to start uploading the part 3 pieces soon.

God Bless,

Hi Jason

These cores are used in about every power supply in the form of noise filters and as little magnetic amplifiers.
They are also used in crossover filters in speaker systems where they only pass the signals in the low frequency range so the woofers doesnt get signals above certain frequencies it cannot respond to , but these are mostly vertical wound coils so they do differ somewhat but the principle is the same >getting rid of high frequency peaks.

I have used them in my tube rectifier as to cancel out/short cut the high order harmonics.
It's about the same thing.

you can always DC bias the cores to get them closer to saturation.

another observation from the videos:

in the spool TPU,Ã,  we now can see the two wire loops with another smaller wire wound around them, like a helix.Ã,   This appears to be the same bundle of wires seen in the large tpu, connecting the two toroids in the center to the main toroid body.

It's that "squizing the hose" that SM mentioned.

All these variations in the TPU topologies can be frustrating, but actually they can help us understand the principle of operation, they are like extra "xy-points" that we can "curvefit"
