EHT power supply design and construction

Of course you know that Lori H. and Julie have received multiple requests for a "simple" explanation of parameter selection & calculation
I took the liberty of telling them you were laboring under that assumption
Thank you! As a matter of fact I've 'sketched' a rather cursory 'outline' on the subject (via a private blog entry) - to be moved into 'public view' (on this thread) upon completion of 'fleshing-out'/proofing...:cool:

Many sincere thanks and very best regards

Please be advised that I am currently experimenting with formatting/alternate character sets with the aim of enhanced clarity/legibility -- please expect my post Thu evening/Fri morning...

Best regards and, again, many thanks!

This is beautiful! The UK server locked out.
Theo just so u know that's not bug! So when you registered your new gmail addy with Zenmate you got free trial on Premium plan for just a few days! So when trial ended you were automatically put on free plan so only Hong Kong, Romania, Germany and US servers are available! So like ur finding out cuz of all the traffic on free servers they don't work vry well! So it's like playing musical server chairs just staying connected:mad:! So I say they need to find way for ppl to pay totally anonymously cuz like u saw paid service is vry good! But there's totally no point to VPN for privacy if they have ppls cc# or banking info! So it's basically same problem as with paypal! Also even though they accept blind chashier's check ppl are way too paranoid to accept mail w/o return addy filled in:rolleyes:

Oh Yeah. Julie wants all to know she'll up the formal report as soon as possible.
Theo I say that's not totally necessarily now that @Hypatia's Protege has guidance for choke post! So HP it's totally your call but I say since there's no surprises we need to just keep up momentum on important stuff instead of acting like committee:confused::)?

please expect my post Thu evening/Fri morning...
HP No offense but I'm totally saying I'll believe it when I see it:D!
 
@Aleph(0), @theodoravain

Please be advised that I've abandoned all hope Re: 'Tex' rendering once and for all! -- 'Tis nice when it works but it doesn't (for me anyway:(:mad:)

But to continue -- I've added each of you to the 'viewers list' of my (nearly complete) 'inductor exposition' blog entry HERE - Should you read this prior to my completion of said presentation, I'd appreciate your taking a moment to 'proof' it for obvious (i.e. stupid) errors/omissions (e.g. spelling, arithmetic, grammar, etc...)

Jezzzze!
I begin to realize that preparation of a cursory presentation is significantly more difficult/challenging than development of a proper (i.e. comprehensive) course!o_O

Email received! -- Please be advised that I've incorporated your suggested of addition of a FAQ -- Thank you!

BTW
theodoravain's email message said:
...link isn't working...

FWIW I believe I've 'hit' on the most common/likely causes of confusion? Any ideas/specific suggestions are most welcome...:)

Again, while logged on you and @Aleph(0) have view access to the work-in-progress (to be moved to public view on this thread shortly).

For your convenience, below is a summary of my 'best guess' at likely FAQs -- Did I miss anything in your opinion? -- Thoughts?


-Copious 'Interacting solutions' (knowing where to begin)?

-Our choke's significantly greater physical size and Isat by comparison to those seen in YouTube demo circuits, etc..?

-Choke 'over-designed' for exclusive use in test circuit?

-Viability of alternate forms/materials?


Many thanks and very best regards

If it messes up for you everywhere take it as plugin issues. I don't know? Could be TEX rendering uses a script?

Yeah really! Watching trees grow in January isn't my idea of a good time.

Of course it is! Equivocal purpose? Nebulous scope? Well, I know it's not a task I'd relish. But if that's how they want it..?

Who needs science! We've got Youtube!

Did I miss anything in your opinion? -- Thoughts?
Well, that "square in the works" means you'll be hearing pedants tell you to save copper and double effective Imax making 32.7uH by paralleling four inductors wound to 130.8uH (20 turns) with AWG 28. Never mind the extra work and iffy current balancing:rolleyes:

I wouldn't burn too much ACh trying to anticipate them! You can bet they'll be in touch soon enough!:rolleyes:

Thanks!

OBTW Why are you keeping the entry out of public view?

---Emphasis added---

Indeed -- and for less 'Cu economy' than the above emphasized text suggests...

Hey @theodoravain granting that your erroneous citation is down merely to a typographical error - I've a responsibility to our readers... I sincerely request that you handle my (not-infrequent:oops:) oversights in similar fashion!:cool:

So, with no further Ado

For:
Rs=the winding resistance of each inductor in a series arrangement.
Ds=the diameter of the conductor forming 'winding s'
Rp=the winding resistance of each inductor in a parallel arrangement.
Dp=the diameter of the conductor forming 'winding p'

Assuming single layer, cylindrical-conductor windings (and, hence, conductor lengths/resistances in direct proportion to turn count):

Eq. 1) Rp=2Rs*(Ds/Dp)^2
Re: Eq. 1 -- Quadrupled inductance implies doubled turn count).

Eq. 2) Rp=16Rs
Re: Eq. 2 -- Resistive parity demands Rp/4 = Rs*4

Eq. 3) 8 = (Ds/Dp)^2
Re: Eq 2 -- Following elimination of Rp and factoring.

Eq. 4) Dp=Ds/√8
Eq. 5)
Dp = 1.291mm/√8≈455μm = DiaAWG16/√8 = DiaAWG25

Thus it may be seen (Re: the parallel arrangement) that maintenance of resistive parity with the series arrangement mandates use of AWG 25 (as opposed to AWG 28)
...

Gotta dash! -- Will return with a comprehensive reply and (hopefully) the completed 'choke discussion':cool:

Very best regards
HP:)
 
granting that your erroneous citation is down merely to a typographical error
LOL! You're going to love this! You know that "√8" is too ugly for the light of day! Looking at my notes I see my apple cart started listing when I "lost the extract" (proceeded with √2 instead 2√2). Yeah, well.. It's been a refresher on the virtues of always checking results no matter how simple the problem.

I sincerely request that you handle my (not-infrequent:oops:) oversights in similar fashion!:cool:
Really! No need for the velvet glove, my friend! You know I'd have been merciless the other way around.
I've a responsibility to our readers...
Really! It was a courtesy to me as well! I know I prefer honest criticism to evasive deference.


Thanks!
 
If it messes up for you everywhere take it as plugin issues. I don't know? Could be TEX rendering uses a script?
It is my observation that proper rendering of 'TEX' formatting is distinctly browser/configuration specific - while such may indeed owe merely to incompatible plugins/extensions, courtesy to our readers demands eschewal of so 'fragile' a feature -- Too bad!:( It does splendidly for math pretensions - when it works...

Theo I say that's not totally necessarily now that @Hypatia's Protege has guidance for choke post! So HP it's totally your call but I say since there's no surprises we need to just keep up momentum on important stuff instead of acting like committee:confused::)?

Ok already! -- Message received!:rolleyes:

Of course it is! Equivocal purpose? Nebulous scope? Well, I know it's not a task I'd relish. But if that's how they want it..?
I hear you! But hey! Let's not disparage/discourage inquisitiveness and desire for comprehension!:cool:

^That one doesn't.^ It explicitly says I'm not invited.
That's merely a 'convenience link' to my blog's 'scratchpad' (such that I may access said entry directly from this thread sans loading delays experienced when visiting my blog 'home page' --- FWIW you are now added to the 'viewer list' though I can't imagine such being of any utility/interest?:confused:

Love your suggestion of 'sheeting it.
Empirical though it may appear - many find said approach quite useful where significant 'compromise evaluation'/'trade-off juggling' is at issue - Especially where matters of personal preference are a factor...

Who needs science! We've got Youtube!
Aye! There are a few in every crowdo_O:rolleyes:

Well, that "square in the works" means you'll be hearing pedants tell you to save copper and double effective Imax...
BTW many thanks for alerting me to/reminding me of that! -- Please rest assured that an appropriate 'preemptive FAQ' will be added pre-publication!:)

I wouldn't burn too much ACh trying to anticipate them! You can bet they'll be in touch soon enough!:rolleyes:
No fear of that:rolleyes:

OBTW Why are you keeping the entry out of public view?
Publication prior to completion/initial proofing would serve no useful purpose, and, I daresay, be with not-insignificant liability to confusion, misapprehension and --in light of the subject matter (i.e. EHT systems in general)-- possible safety concerns --Stated otherwise: 'Conception' is properly conducted 'in private';)

"√8" is too ugly for the light of day!
you'll be hearing pedants...
Indeed! I believe I am?!:p:D

HP I definitely hope so cuz like ur saying whole decoupling choke thing is being dragged out way too far! Now I totally know _offline life_ is keeping u vry busy and also u got slowed up on choke post cuz of trying to use TEX format. But I also say repeatedly breaking sincerely set deadlines is just bad PR cuz it can make ppl think we're not really committed:(!

Stated otherwise: 'Conception' is properly conducted 'in private';)
HP I say careful or you'll have thread lurking _Moral Majority_ clicking report button:eek::rolleyes:!

You're correct of course -- That said, I aver that 'the error of my ways' lays not in want of alacrity but, rather, in my over-optimistic assessment of my schedule (Spec allocation of 'free time') and, hence, declaration of definite timelines in the first place:oops::( --- At this juncture I can do no better than offer sincere apologies for the delays and assurance that I will make every effort --and fully expect-- to complete and publish the relevant post ASAP (within the next 48 hours) -- While I do not anticipate further disruption in this matter owed 'asynchronous' outside demands upon my time - neither am I in a position to make promises...

Well, ok you're not going to like this but it needs saying! The both of you are being way too hard on yourselves! Bringing hard science to "the million" in a way that garners interest and stimulates creativity is a formidable and noble ambition under any circumstances! Staying with it despite increasing real world demands, in the face of the crap flung your way by a vocal minority of "entitled" ingrates is nothing short of phenomenal! You know that you have our (your majority loyal following's) undying gratitude for all you're doing!

Thanks!

Theo HUGE TNX for understanding! But you totally need to remember nobody is holding like _gun to our heads_! So since we took it on ourselves it's totally our responsibility to see it through and own blame for delays and when our advice (like for disassembling FBTs:oops:) wastes reader's time and resources:(!

Staying with it despite increasing real world demands, in the face of the crap flung your way by a vocal minority of "entitled" ingrates
Theo I totally appreciate you speaking in our defense:)! But being 100% fair they had vry good reason for getting ragey! So it's true we provided materials free of charge but our bad advice cost them something totally more valuable than money! By which I mean their TIME:oops::(!

Theo like u you know I always call BS when ppl say _you can't complain abt free service_ cuz nothing ppl are given reason to count on or invest their time in is really free at all! So I say anybody offering gratis ANYTHING is totally bound to same code of integrity as somebody making financial profit! Cuz it's true ppl should be able 2 count on getting at least what they pay for and time is way bigger payment than just money can ever be!

Bringing hard science to "the million" in a way that garners interest and stimulates creativity is a formidable and noble ambition under any circumstances!
Theo tnx! But I say it's not really that complicated! Cuz encouraging interest in abstract subject (and so abstract thinking) is just a matter of linking it to subject of interest in their _tangible_ reality:cool:!

You know that you have our (your majority loyal following's) undying gratitude for all you're doing!
Theo Tnx! But I still say we need to do better:oops:! Cuz _real world demands_ are our problem not theirs!

Now Theo I totally have to say this so everybody can know! You being professional educator (by which I mean college prof) is totally huge for us! So I know you have doubts cuz of how ur claiming non-parallel relationship of physical science vs social science but even if it's totally failed analogy I still say education is education! So you can totally help us reach and understand needs of ppl whose perspectives are completely different from ours! Also you have skill (talent?) of knowing when 2b teacher and knowing when to be peer even with same person which is vry important in adult education cuz it's like HP says _newbie to a subject newbie to life_:cool:!

OBTW @Jazz2C:
I'm asking you to stop acting like a baby and be back participating on thread ASAP:mad:!
So for benefit of ppl _outside loop_ JC is POed at me for suggesting Hetfield avatar cuz he says he's _a more sophisticated guy than to go around like shirtless neanderthal_:rolleyes: So JC don't put that on me! Cuz it was your _beloved_ HP who said u resemble _20 something_ Jim Hetfield (which I totally agree) and it was YOU who wanted avatar that looks like yourself! So I guess you forgot to clue us in abt _sartorial requirements_:rolleyes:! BTW I say you should keep present avatar cuz I say _VDG hairstyle_ is perfect for HV discussion! So having sense of humor isn't crime:)!

Anyhow I say it's totally ironic that JC totally insists on shirt and Theo got in _hot water_ for (almost) not wearing one:D:D:D!

PS HP

Plz just publish choke construction post intermediately after you're back on here! We can totally worry abt TEX (or finding alternative) when we're on to more math intensive presentation! Cuz for now even just _ascii math_ is way better than crickets:rolleyes:!

Yeah, well.. "doubts" is an understatement.
So you can totally help us reach and understand needs of ppl whose perspectives are completely different from ours!
So you say. Really, praise is gratifying!:rolleyes: But what I need is a how?
Also you have skill (talent?) of knowing when 2b teacher and knowing when to be peer even with same person which is vry important in adult education
Well that's damn overthought! Do you think educators belong to an elite social class all our own? It's not like I walk around in a daze of "academic privilege" thrilling the "commoners" with randomly bestowed trinkets of condescension. Are you getting me? I'm a human being first and an educator in structured settings of willing students! Yeah! So.. If I'm coming off as a cynical bitch it's only because that's what I am! Sorry! That's what you bargained for! But really! Let up on the effusive adulation! Sincere or not it rings of burdening me with unrealistic expectations!

What's up with HP? Did you see her latest (on Axnmultics)? Looks like she's near the end of her patience? Well I'd understand if she chucked it in! But really the blame is hers! Attempting to make silk purses of sow's ears can be taken too far! Time she faced facts! Provision of accessibility to "all interested parties" is overreach on a delusional scale! Strict observance of clearly defined language and math/science prerequisites is imperative! You wanted my opinion as an educator. Well now you have it.

Thanks!

Theo just what you're already doing! So now that ur AAC member it can be public on here which is huge for improved communication:)!

Are you getting me? I'm a human being first and an educator in structured settings of willing students!
Theo you totally need to chill cuz that's exactly what I'm saying! You treat ppl as cognitive equals and social peers unless and until THEY put themselves in role of student! So I'm saying that's vry good thing:cool:!

If I'm coming off as a cynical bitch it's only because that's what I am! That's what you bargained for!
Theo you have as much right to act like _cynical b!tch_ as I have to act like numpty! But I totally resent challenges to my sincerity:mad:!

Let up on the effusive adulation! Sincere or not it rings of burdening me with unrealistic expectations!
Theo u need to give it a rest cuz nothing's changed except that now ur helping us in public view! Now I'm going to say something! Maybe I am holding you to unrealistic expectations or just making unfair demands on your time? If so I'm vry sorry and we definitely need to talk abt it! But don't you dare say I'm trying to cajole you into extra work or like that! Cuz both of us are way smarter than that:rolleyes:!

What's up with HP? Did you see her latest (on Axnmultics)? Looks like she's near the end of her patience? Well I'd understand if she chucked it in!
Theo that's not the impression I got at all (also I know better from being in contact with her all along)! She's just vry frustrated trying to find time for work on EHT series! So like you know (but since some ppl don't I'm saying it here) HP basically took early retirement but keeps getting drawn (I say guilted:rolleyes:) back on case-by-case basis!

Well I'd understand if she chucked it in!
Theo just RELAX! Cuz I can totally guarantee that's NOT going to happen:)! Cuz I totally know HP is more passionate abt this than all the rest of us combined:cool:!

Time she faced facts! Provision of accessibility to "all interested parties" is overreach on a delusional scale! Strict observance of clearly defined language and math/science prerequisites is imperative! You wanted my opinion as an educator. Well now you have it.
Theo scope is only _delusional overreach_ seen though lens of conventional approach to instruction:)!

You wanted my opinion as an educator.
Theo we definitely do! But we need u to be thinking _outside of the box_! Which I say isn't asking so much of someone with your intellect and creativity! Now here's honest disclaimer! Accolades aren't flattery just fact! So like HP says LIVE WITH IT:p!
 
Come off it, Julie! My self-assessment isn't a challenge to your sincerity! Would you have me believe you're above honest misconception?
Theo we definitely do! But we need u to be thinking _outside of the box_!
Well then! Here's a double-shot of that brutal honesty you so admire: You must be aware that the reason things don't get done around here is less to do with HP's absenteeism than the perfect storm of her perfectionism and certain disruptive influences coming from the AT and development teams (you know who I mean!). Motives (in my opinion all bad) aside, their self-satisfied intransigence, dirt ignorance, and pugnacious belligerence bring nothing of value to the effort! While I can relate to HP's desire for a "realistic mix of personalities" and the theoretic merits of a tough audience the present situation is not constructive! As stated, I view HP's ambition to reach "all interested parties" as a noble, even if doomed, cause! But "rehearsing" to reach trolls, vandals and abject morons? Really?:confused: Are you not aware that the present "pretty print" (laTEX) formatting debacle is down to the bleating of a single FDNet fora advisor? So how'd that work out? Choke construction delayed for over a week, HP (in her own words) "fed up with the whole thing"!:rolleyes: Not with the disruptive jerk, mind you! With unreliable rendering of a format nobody else suggested or gives a rat's A. about!

Well Ok... You and HP want me to bring the effort back on track.. Simple!

1 Lose the pukes immediately! That means no further warnings, negotiation or appeals! Close their (provo, gtm and fdn) accounts, block their gtx/sgtx profiles, purge their content (including history archives) and email notice!

2 Inform those on "thin ice" that there will be no further warnings, their next troll will be their last!

3 Most importantly clearly define constructive criticism and well indented suggestion from disruptive "courses of conduct".

4 Don't be ashamed to pay them WELL for their time! They deserve it!

5 To prevent any possibility of interference from suggestions 2, 3 or 4, Provide an overt means for anonymous Alpha Test feedback.

6 KEEP REMINDING HP THAT SHE CAN'T SAVE THE WORLD!;)

Thanks!

Theo you were basically accusing me of trying to wheedle your cooperation with insincere complements and like that! So I totally get it's unintended _side effect_ of your self effacement ACT but it's still not nice:rolleyes:!

certain disruptive influences coming from the AT and development teams (you know who I mean!). Motives (in my opinion all bad) aside, their self-satisfied intransigence, dirt ignorance, and pugnacious belligerence bring nothing of value to the effort!
Theo ur being way too nice cuz I totally agree!

Are you not aware that the present "pretty print" (laTEX) formatting debacle is down to the bleating of a single FDNet fora advisor?
Theo I totally agree that AJ is just a malcontent trying to obstruct and disrupt with insincere suggestions and complaints! But it's still fact that proper formatting of formulas and symbols would be vry nice and totally easier to read! So we felt it was worth having another look at trying! But browser extensions and script management schemes make it unreliable:( Anyhow I say AJ is right abt one thing despite himself! In this day and age it's totally lame that reliable, 100% native LaTex-type rendering isn't standard markup language functionality:mad:!

Choke construction delayed for over a week, HP (in her own words) "fed up with the whole thing"!:rolleyes: Not with the disruptive jerk, mind you! With unreliable rendering of a format
Theo I can totally tell you what HP is _fed up with_ with is constant unanticipated demands on her time taking her away from promises and commitments to EHT project! Now for AJ since like you know he just spontaneously resigned from team and HP closed his profiles I say that's totally moot! So I say basically gritting your teeth over problem that's not problem anymore isn't vry constructive either:rolleyes:!

1 Lose the pukes immediately! That means no further warnings, negotiation or appeals! Close their (provo, gtm and fdn) accounts, block their gtx/sgtx profiles, purge their content (including history archives) and email notice!
Theo you need to shoot me an e cuz you know it's already done deal? The _big five_ are banned and their content is totally scrubbed to avoid intellectual property issues! Also Legal formally notified them that we will be going the _cease and desist route_ if they attempt any further contact at all! So are you saying we missed someone who needs to go? So plz remember we don't insist on their being nice or even being fond of us! Just that they're totally sincere:)!

2 Inform those on "thin ice" that there will be no further warnings, their next troll will be their last!
Theo we don't have _grey area_ list! They're either sincere partners (including honestly scathing critics:cool:) or not! AFAIK the _nots_ are out! So if you disagree it's totally important 4u you to tell me, Laurie or Babs ASAP (by which I mean b4 HP's return) cuz she's in bad enough mood already w/o having petty _team personnel_ BS waiting for her when she's back:eek::rolleyes:! Theo also if you'd just accept administrative role you could handle these sort of problems yourself! So I understand abt wanting to focus on content instead of _team politics_ but I say just think on it! Now you ARE focused on administrative issues with nothing to do abt it but complain cuz YOU refuse 2 step up to admin responsibility:confused::rolleyes:

4 Don't be ashamed to pay them WELL for their time! They deserve it!
Theo I totally agree! It's what we should have been doing through whole program! But like you say it can only work if alpha feedback is totally anonymous which also means review should be through MC form so they won't wry abt being IDed by _style_ or like that!

Now I'm going to say something! Alpha team shouldn't wry about _hard feelings_ cuz of unfavorable reviews! I can totally say false _good_ review is like 1,000 times worse than totally blistering negative feedback could ever be! So we need to know where we REALLY stand! Not (necessarily) what we'd like to hear:)!

3 Most importantly clearly define constructive criticism and well indented suggestion from disruptive "courses of conduct".
Theo it's SINCERE vs INSINCERE! That's all there is to it:)!

6 KEEP REMINDING HP THAT SHE CAN'T SAVE THE WORLD!;)
Theo I say u need 2 give me an easier job! Like transplanting The Rockies to Venus or like thato_O:D
 
@HP Well, ok! I relate to your postponement of magnetic principals, but this ignorance (coming at us from Provo) has to end now!
As we all know, magnetic energy is not stored in an inductor's gap anymore than electrostatic energy is stored in a capacitor's dielectric ("soak" and piezo effects aside)! It's as saying electrical energy is stored in the "drop" across a resistor!
Well, you know it's that kind of lazy stupidity that makes me doubt the integrity of the physical sciences! Why must Phy Sci students suffer compulsory use of childish analogy and cognitive crutches on a magnitude unseen in any other area of study? So appreciation of reality is an unjustifiable extravagance as long as we can contrive a sanitized narrative fitting the model? Yeah! Right!:rolleyes:

I want everyone to know students aren't the problem! I'm addressing conventions wrongfully treating them like idiots!

Thanks!
