Slewmaster - CFA vs. VFA "Rumble"

[rsavas]

How about PM me so can take this work offline?
It is also possible to try doing this design using the designspark s/w, so it easier to share with everyone.
So I assume that you have simulated this design using orcad pspice and not using ltspice?

 

[EDDELARUE]

Yes. I have been simulating with pspice from OrCad 15.7. I believe that OrCad and LtSpice uses the same core for simulation. Maybe someone in this forum can say about this.

I will prepare the files to send them to you in PM.
If you prefer to use DesignSpark, no problem.
I ask you to wait for files at least until tomorrow, ok?

 

[rsavas]

maybe you can help me learn some orcad pspice as i struggled with it. i am pretty good with layout however. i am just getting started with designspark.
Take your time i am in no rush

Can someone say which of OS's designs is most sensitive to oscillation from capacitive loads?

 

[yngvejos]

Does anyone have a BOM or a list with LS for the Spooky IPS?

 

[SyncTronX]

If any of you guys have contact info for OS,
you might let him know that I think AOL still has
a dial up network, if he need access.

 

[still4given]

Smart phone?

It is just a matter of output coil and miller cap (compensation). The outputs stages are the same, anyway, more paralleled power devices, better for capacitive loads..

 

[ostripper]

All these designs have no load issues..
I have even built my symasui.
Change the servo dc feedback to 5.6k on both
The spook and symasui , main Fb
Ratio... keep the same . 30x gain and 50ms
DC settling is the result.
When I come back , all the present
Designs will have "refinements".
Quite spectacular performance !
OS

 

[ostripper]

Built the "ND" , too. So fast , it
"Error corrects" a low biased
EF3. RN Marsh will get my test OPS
and this IPS when I move.
Typing on this phone sucks

[jwilhelm]

Welcome back!

 

[ostripper]

Major Pita to do this!
It might not qualify as "back"

 

[jwilhelm]

You need a better phone then. Or tether it if your data plan supports it.

 

[ostripper]

No credit. Need to get to a first world area. A mobile plan is out
Of the question.

 

[Esperado]

No credit.

France is nice , if it weren't for the French. No joke aside France is very nice, I like the south and the wine and the Bretagne coat and... Toulouse Loutrech

where so Esperado?... Comparateur des offres internet Fibre Optique en France Métropolitaine

numericable? ~800Mb/s

the prices are in fact in line with those in Portugal (considering the vodafone/meo/nos offers)...

where so Esperado?... the prices are in fact in line with those in Portugal (considering the vodafone/meo/nos offers)...

The speed offer: Freebox - Offre Internet jusqu'à 1Gbit/s _{(débit descendant)}
The phone offer: Freebox - communications internationales vers 108 destinations, vers les téléphones mobiles, incluses
The TV offer: Télévision Freebox
The price: Freebox Révolution

(Not exactly the same prices than in Portugal. I was First at Cabovisao, and now Meo. ;-)
(I guaranty-you I'd never paid one cent more than 30€ in 10+ years, at Free. In Portugal, I had bills > 100€ while I try to use my phone like if i had to buy the country at each call. ) But i think we are a little off topic, no ?
