Hi Peter,

Excellent tutorial and build.

I'm thinking of building one myself, using a Raspberry Pi for control.

Is there a full schematic on this Poewr Systen that anyone can use for himself?

Best regards

Luis Figueiredo

Just to give a general idea of what my end game looks like i am going to run 0-32 volts around 8 amps. What i will be changing in the diagram is the transformer and rectifier and i will be changing the tip31ag to a 2n3055 npn waiting on the heat sink for the 3055. Also I am thinking of using the ATX as a secondary supply and powering the Op amps of the rails of that supply so that i dons't push the op amps so close to the max V. But that part is still on the idea board.

Hello Sir i know this forum post is rather old and i hope someone still views it that may be able to help me. i have the circuit mocked up on my bread board and for the most part it is working except it seems that i don't have the proper current control and on both my pots it seems that all my control is in the very first 1/4 of the pots. my input power is from a 12v atx supply so my max output is only around 8.4 volts. the pots are very sensitive in that first 1/4 of the turn except for the current pot which dosn't seem to work correctly i was hoping some one could look at my diagram and see if I have something incorrect. don't pay attention to the bridge rectifier. part of the diagram its not implemented yet.

USCDADNYC here again. If at the Bottom of our Posting(s), perhaps we can state which locale (country) we are in. Context (& colloquialisms) are important b/c of Regional Differences in the use of the English Language. Of course we will be making it easier for the US NSA to track us. But they probably know who/where we are Already.

To Pete Oaks: Thx for your prompt Reply. Ack that this project will be considered a "Series-Pass(?)" PSU w/ elements of Switching PS modules/components. In your first video "Power Supply Pt 1 -Intro". you alluded to using Toroids instead of Transformers, that was a Clue that was misread by me. Sorry. AAR I look forward to viewing your Lectures/Videos. I am Not a practising EE but an IT/Patent-Atty. One who is always looking for Prior Art. Prior Art is term of "Art" (sorry about the Pun) that describes the State of the Art (Sorry about the Pun again) of the field of endeavor. IDK (I Don't Know) anything about British Patent Law/System, but most" First-World" Countries' Patent Systems has their roots in Prior Art. I believe India (definitely NOT a 1st world country) does NOT. I guess when they went Independent (of the Crown) in 1949(?) they went "Off the Reservation" so to speak in terms of IP Law.

USCDADNYC (Edward L. Yee also aka ELY) here. To: Pete Oaks: Sorry, I am a late comer but I have to ask whether you would describe your Modular Power Supply ++ as a "Switching Power Supply"? I was a BSEE(1973) and have never gotten into SPS's.Used SPS's but never evaluated the circuitry. Was waiting coursera.org to run their SPS course again, but maybe I can get a feel for SPS's w/ your Project. Many Thx. from across the Pond (I think) b/c I think you are in England while I am in the (former) Colonies

Hi Peter,

Wonderful videos, wonderful projects, I am studying in detail the Modular Power System project, having gone through many, unarguably the best on the web, all very much appreciated.

Best Regards, Gilbert.

Hello, First off great video series im eager to so the completion. I have a few questions, first in your original plans you only use a single dual op amp but the revised which i am have difficulty understanding uses 4 op amps 2 for voltage control and 2 for the adjusting.? two if at all possible do i have to install the second set of op amps for this supply to work? i am currently to the build stage when looking back through i seen the updates plans i was like sun of a gun. if i need to build the second set of op amps thats ok i have a lm3224n ill use. third any chance you can post the revised plans but in the same format as original? sorry if that is a stupid request but for some reason im having a heck of a time reading it. Thank you.

Thanks for a great series. I would love to be able to download the final schematics and BOM för this project so i can start collecting parts.

Thanks from Sweden!

Hi Peter,

I'm following your project, it is very interesting for me that I'm at the very beginning.

You are a very good teacher!!

Great post! I have bookmarked it as it will be useful many times. General approach with good real applications of the concept.

I love your content, Sometimes the video can run a bit long though.

Thanks for your great work,

Clem

PS. Have you seen The Workbench: Building a Benchtop Power Supply Any comments?

I'm interested in this as well. I'm looking forward to watching the videos.
