content: 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 thisCredit card sized power supplyto 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 Yearhttps://ibb.co/9Y4F0FF

content: 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.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.pdfYou could also call contact prof. Rivas and ask him nicelyCheers,DC1MC

content: 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.

content: 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.pdfa/ 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/ précise 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 ChanceJon
