Hello Grum!

Litz wire is a type of cable used in electronics to carry alternating current. The wire is designed to reduce the skin effect and proximity effect losses in conductors used at frequencies up to about 1 MHz.[1] It consists of many thin wire strands, individually insulated and twisted or woven together, following one of several carefully prescribed patterns[2] often involving several levels (groups of twisted wires are twisted together, etc.). This winding pattern equalizes the proportion of the overall length over which each strand is at the outside of the conductor.

The term litz wire originates from Litzendraht, German for braided/stranded wire[3] or woven wire

Litz wire is another method, which employs a stranded wire with individually insulated conductors (forming a bundle). Each thin conductor is less than a skin-depth, so an individual strand does not suffer an appreciable skin effect loss. The strands must be insulated from each other—otherwise all the wires in the bundle would short together, behave like a single large wire, and still have skin effect problems. Furthermore, the strands cannot occupy the same radial position in the bundle: the electromagnetic effects that cause the skin effect would still disrupt conduction. The bundle is constructed so the individual strands are on the outside of the bundle (and provides low resistance) for a time, but also reside in the interior of the bundle (where the EM field changes are the strongest and the resistance is higher). If each strand has a comparable impedance, current is distributed equally among every strand within the cable.

The weaving or twisting pattern of litz wire is designed so individual strands will reside for short intervals on the outside of cable and for short intervals on the inside of the cable. This allows the interior of the litz wire to contribute to the cable's conductivity.

Another way to explain the same effect is as follows: the magnetic fields generated by current flowing in the strands are in directions such that they have a reduced tendency to generate an opposing electromagnetic field in the other strands. Thereby, for the wire as a whole, the skin effect and associated power losses when used in high-frequency applications are reduced. The ratio of distributed inductance to distributed resistance is increased, relative to a solid conductor, resulting in a higher Q factor at these frequencies.

Litz wire has a higher impedance per unit cross-sectional area but litz wires can be used at thicker cable sizes, hence reducing or maintaining cable impedance at higher frequencies.

Hi everyone,

I have just killed 2 birds(2 successful experiment) with one stone(1 hour)late last night.


Dear magpwr.

That was a lengthly piece of text and very interesting. Please show diagramatically what you did.

Cheers, Grum.

Can someone please translate this video to English ? Thank you!

It seems maybe make mistakes. Похоже сам он путаеться, поэтому трудновато переводить или называет такие термины де может быть и трансформатор и ЛС контур.
Baisicly it say, that transformer ant choke is not inportant, that need exactly tap frenquency from generator to frenquency LC circuit it must be same, you can make mistake in 5-10 herc. Need use frenquency 20-30-40-50 kiloherc. Fist put any capasitor, then wth GIR, in english is other words, meashure CL circuit self frenquency. And then with generator (I think it paste pulses) find this frenquency.  If you not can meshure LC circuit frenquency, then ajust is wery hard, with GIR, you can more easily ajust. And say, that induction flash is must be 10 times shorter than self resonating frenquency LC circuit. I asume this flash is from transformer or maybe from choke. But in this place he complicated explain. I think transformer must have about 5-10 turns. Then it say how know or it is self runnig. That need put diode like in schematic and it not let go curent to oposite side and look in miliampermeter and then curent drops to zero, then it selfrunning. In schematic this diode is.
I think it say, that if transformer if have 200 kiloherc self oscilations, then LC circuit must have 20 kiloherc. So transformer not have capasitor, it only have self capasitance, so it resonant frenquency is wery hight.

Hi Grumage,

Sure i will definitely create video in few days and explain in details in video.I will try to create 2 video since it's 2 experiment. It's rather late now at 10pm.


For Antanas /LITHUANIA experiment-

To save time i have just purchased 2- "Ignition Spark Tester With Adjustable Spark Gap" from Amazon <$10 ea.This will surely speed up testing time no constant knocking on motor spark plug to adjust gap as shown in video.

The 2 mosfet driver i will using my  2013 favourite MOSFET SPW47N60C3 rated 600Volts RDS on at 0.07Ohms which is also used in my HHO experiment.The best place to buy is ebay which a seller in China or Hong Kong whom offer free shipment which is most important factor.He sells in bulk of 5 <$20 .

Currently i am sourcing locally for HV diode and HV caps and  HV flyback transformer with exposed ferrite to run  wires around it.I am quite particular about HV diode latency and other specs as well at the moment can't decide yet.

This is the best web site which did research on 3 kinds of HV transformer and which one to use
http://www.volny.cz/jmartis/flybacks.htm

This is a interesting component i have spotted in above site with "total 2 outputs -1 is inverted"  which the pulse width and frequency can be adjusted.A better choice than 555 or 556 or using my processor.
SG3525 (Component for hv flyback driver) input- 8volt to 35volt.

Specs

For the rest-
*************This a HV experiment.My experiment is merely to replicate and to show if there is OU effect.I can't be held responsible if your heart suddenly stop working after being electrocuted ********** :-\
