I have been a student too. You will never become a better student let alone a good engineer by copying what others did. Get over it, you have to invest.
If you read my old posts and other publications carefully, you will see that you can learn from what I have shared.
The real question an engineer should pose himself is: what do I need, how do I realise this functionality and performance, rather than to look what is available on the market, regardless of the fact if it is a closed design or open source.
The reason that I am less active on fora is as stated by Mike Gergen, earlier in this thread.
best,
Guido
You (and I) are old fashioned Guido.
Nowadays it is normal to look around on the WWW first to gather the info; it is fast, and why check things yourself when others have done it already? It is rule even on high schools and universities.
In my opinion this is one of the main reasons that the good old skills seem to disappear more and more.
The info is too easy available around the corner; one does not have to work the old fashioned way.
To illustrate: in eastern european countries (most of them EU members now) many of these "old days" skills are still preserved; in our world it becomes more and more difficult to find real craftsmen.
Forums like these can be great, but at the same time can show their drawbacks.

hi Pieter,
I agree, I know how it works, I also lecture and see how the majority of engineers work. I also know that a lot end as purchaser or equipment engineer rather than as a designer. An example last week was a student who had to design a simple motor driver for a volume control potentiometer. He started to browse for "motor driver IC". In stead, he could have asked himself "what do I need". He could have ended up with a simple circuit containing 4 or 6 transistors and a few resistors.......
Actually, I don't care. It is way more fun to totally understand what you are doing, rather than to reproduce what someone else has done.
The majority of designers in the audio industry are application engineers; they apply what others have engineered. Only a few brands are a bit exceptional.
Real innovation is way more satisfying .....

@ "old skilled" to be honest and with all respect it is disappointing how you judge me just by one question.
Im already a succesfull engineer - you don't have a patent in cooperation with a german car manufacture just by copying 😉. However it is not the point to discuss my internships as mech. eng. bachelorstudent.
@Guido: It is interessting. Unfortunatly a lot of theoretical Physicits say such arrogant things about engineers - they say it is no innovation just to use old physics (classic electrodynamics) some kirchhoff laws - Engineers are only applying Physics.... I don't like it if someone with a lot experience is thinking this way of other people.
It is the normal way of innovation that old ideas are investigated and then rearranged to create better ideas. Even you guys are using gyrators, cap multipliers etc which arent your ideas. Currently I'm working on my Masterthesis at a particle accelerator - the way how it works: research and understand, verify what others did and then create your own ideas based on it.
So my question how it comes that some of you think that you generate your ideas totally shut off the outer world without any input?

Because that is not what you asked. The first post; you asked for the schematic to the Tent regulator so you could integrate it into your PCBs.
That is not building on the shoulders of others. That is STEALING.
Why don't you look up the numerous threads here about shunt regulators and why they do what they do. Then come back and ask us for info so you can then, "build on the shoulders" of others.
Why don't you ask Guido what is so special about his regulator and why he made the design decisions he did. You might be getting a different response from us.

Again read my response on the first and second Page of this thread. It was never my Intention to steal anything.
Don't take my remarks too personal; it was more a general personal statement.
When you are one of those students who investigate in order to innovate, the future is yours.

yes sometimes I do, I mentally shut the door in order to come up with solutions as I do not want to be influenced by what is readily available.
So that is a point to create a good world...🙂
For Guido, just one question:
Can you tell me please what is the importance of the ferrite element between the two transistor collectors? After simulations (by me) it causes only more trouble (resonances) as benefit.... Thanks!
I took a 1206 smd type from Murata, Rs=0,025 and 120R@100MHz (3A), and have calculated the Xr value (200uH).
Should it have the function of overall noise reduction or is it built-in because of instabilities?
I made the circuit with snubber element stable (without that I had strong oscillations).

so how does the exact lumped element model look like that you included in the simulation ?
Not at all, DCR is not really interesting
You forgot to model the RF losses. WatrixReloader could help you out here, since physics is involved (wink, wink).

Thanks.
The question: "Should it have the function of overall noise reduction or is it built-in because of instabilities?" remains open or? 🙂
