Successful TPU-ECD replication !

[EMdevices]

How's it going over here guys?

c0mster are you taking your "toys" and going "home"?Ã,  

So has anybody done a reliable power measurement yet?

Are we dealing with DC-to-DC converters here, or are we converting something more on the side?

So many people have built DC2DC converters, we've seen lots of lightbulbs light up.Ã, 

Where do we go from here?

LM, any more news/diagrams/videos from SM?

@EM Devies I've seen your post alot ...so what is an em device ?

Hi all working on ECD replication,

this is to inform you that due to my lab major re-structuring work I must now stop all the activities. Probably Otto will stay available for any question

Good luck to all

@otto and @ronotte

I have taken some time to look over the ECD that I built. Granted I am not yet settled on the electronics and my frequency generator is on its way from Ebay. I want also to get a Pulse Generator.

But I have done many of testing, man to ECD, with DC pulsing manually at many voltages, some ac also and checking my good old trusty compass and voltmeter It's my way of getting to know the dynamics of the coils at maybe a primitive level, I know, but this gets you acquainted with the base field levels.

Here is a concern on the CC.

The winding starts bifilar primary and secondary, then the primary stops and the secondary continues thus covering the primary. Here is the problem.

Example my build. My primary is weight by weight so I have 8 feet of primary and 30 feet of secondary. Winding starts P/S bifilar till 8 feet then S for 22 feet. This means the primary only has 8 feet of secondary to transfer, not by current, but by induction to only 8 feet of the secondary.

If the object is too generate maximum transfer from Primary to Secondary to Ring, then I feel it is illogical to keep 22 feet out of the transfer potential. Here are a few alternatives.

I am enclosing a drawing of a cross section of a CC (ECD) plus three alternatives that I feel will get the job done more efficiently.

ECD+

Actually, this is the easiest modification. If you wind another primary over the cc, then use that primary as the primary and the secondary as the secondary and then send the frequencies into the bifilar primary. All three would be working their magic isolated so the mosfets would have less load on the negative. Also, you can isolate each internal primary to separate the frequencies.

ALT 1

Start winding the secondary on the coil first, then at 22 feet, continue the wind as P/S bifilar for 8 feet. This will push the induction inwards and your ECD should blast with less juice and your HF secondary would have its shield.

ALT 2

Start winding the secondary on the coil first, then at 22 feet, continue the wind as P/S bifilar for 8 feet, then continue with the secondary to make the outer secondary as the original.

Note: Since the secondary is HF and if you use an outer secondary, it feel it should be shielded. I am thinking that the coil should be in an aluminum tube so all the energy stays inside. You want all those frequencies to bounce back into the ring, not
bounce out into your brain.

Hope this helps!

@wattsup,

I would encourage you to read up on some basic transformer theory.

The bifilar ECD coil is a basic step-up transformer, very similar, if not identical to those used for car ignitions (minus the core of course).

Also, read up and understand inductor coil parameters, and how they affect the inductance value. This will give you insights into the interaction between the P and S coils, and their relative positions.

The ECD and ALT1 scenario are not that much different actually.

You have incorrectly assumed that only 8 feet of the secondary will participate in the mutual induction from the primary. All 30 feet is in fact invloved. It's in the basic theory.
