Hi Romerouk:

    Because my English is not good, A lot of content can only guess, On the multi-strand wire, This issue is really important to me, please answer:

1) a recommended 0.8mm multistrand,
2) Another way of saying they recommended 7x0.125mm litz wire,

    But: accurate mapping from the actual point of view, 7x0.125mm litz wire of the total cross section diameter of 0.375mm, And 0.8mm diameter cross section a lot of difference.
    I understand wrong? What is the right choice?

PS: multi-strand wire in the end is the option of using multi-strand bare copper wire? or choose to use multiple Enameled wire?

Thanks you helping

I am not worried about the 'nasty' posts, they should be left posted.
If I like them or not makes no difference to me, sometimes is good to have them, world is made of good and bad, black and white,...

Still kind of new to this forum, seems I joined at a great time.

I have been studying this and trying to gather the correct parts, etc. I have a half way decent machine shop at my disposal and will start on mine next week...

If anyone (USA based) has been finding good sources on this stuff, please share here. A lot of this is new to me. I have never made my own coils before, but willing to try. When wrapping them, does it matter in how they are wound? Clockwise, counter clock wise when placed? Maybe how the strands are placed? Sorry if "noob" questions, but i am. Thank for the patience..Good luck all

I am using 7x0.125mm wire, the same with multiple Enameled wire.Maybe untwisted wires might do better as Bruce is saying in the TPU replication.It is worth testing all small things to get the best of it.
Before I will start putting togheter the new setup I will do all this testings.
I am still ordering parts.I hate waiting... but I found all parts in UK so that should not take that long.

hi all

please excuse if this is a DFQ**

(i've just looked thro' thread again and can't see this addressed previously, but with *my* eyesight you never know!)

in GL's diag, ok'd by Romero, the load (lamp) is shown as AFTER the DC-DC Converter

surely, it should be BEFORE the converter? (ie across the 47000uF buffer cap)

since the converter is, say, 80% efficient then 20% of all energy which enters it gets dissipated mostly as heat (ie. wasted)

if we put the load on the cap side then none of its energy gets wasted by the converter, am i right?

of course the converter is used to keep the voltage stable for the drive coils, so we have to accept the 20% (say) loss for their energy

but the convertor only NEEDS to stop any EXCESS energy going to the drive coils

so ALL additional excess is available to power any external load(s)

any comments? (or should i just start taking my meds again?)

great teamwork all !
