I need this reference design,but i can't find it :(
« on: January 02, 2021, 11:15:09 am »
Already tried to find something on google by typing the same stuff on this pdf,but nothing & I also tried to upload the picture of this Credit card sized power supply to finally find it and yet nothing ....
At this point i need your help to find this,please if you know where i can find this reference please tell me the link.
Thanks to everybody and have a happy new Year :) :popcorn:

Have you tried emailing the Prof. whose slide it was https://engineering.stanford.edu/people/juan-rivas-davila
https://electron.plus Power Analysers, VI Signature Testers, Voltage References, Picoammeters, Curve Tracers.

Well, considering that the price for "non-cred card" high voltage power supplies from Ultravolt, this is a gold mine and I'm pretty sure that the good professor Rivas and/or his uni got a lot of offers and this stuff is either patented up to the wazoo and/or trade secret to only be disclosed to the Chinese overlords  :-DD.

So, personally I don't think that will be a public available and useful schematic/PCB, but the full paper is here, maybe some smart minds will be able to devise a schematic out of it:

http://file.cpss.org.cn/upload/2e507efd-47ac-43e7-ac5d-9b392b97341d/files/P3-Dr_%20Juan%20Rivas%EF%BC%9ADesign%20considerations%20of%20radio%20frequency%20power%20converters%20.pdf

You could also call contact prof. Rivas and ask him nicely  ;D

Cheers,
DC1MC

To be honest ?
I'm much more interested about to learn everything about pcb planar inductor coils,especially about how to fight the axial field which is their weakness.

Then it makes so much more sense to contact the professor, you'll have to understand the high-level academic explanations though, there were a lot of docs and post-docs in this paper.

FreeWIFI:

The slide of Dr Rivas was not intended to reveal a "reference" design, but was part of a presentation.

Here is a link to a more relivant conference:

http://power.eecs.berkeley.edu/pels/seminars/SUPERLAB_highlights_Nov15_Berkeley_handout.pdf

a/ Rivas is a respected power electronics researcher on a level with Dr Lee at VPI, and Dr Cuk.

b/   planar magnetics is long well known, suggest to research texts, papers and references.

They are most effective at freq 1-200 MHz.

c/ The "credit card" HV PS in the photos was a demonstration of the principles discussed and not meant as a design example.

d/  prĂ©cise your goals, we shall respond better eg build HV PS xx kV yy ma input zz V  OR build planar transformers to learn about them.

Bon Chance
