LPA schematic

[dberryco]

Briefly, I'm looking for some plans/schematic to build a variable 100V 10A DC linear power supply with a very clean, stable, low noise output.

I'm a retired electronics technician (USAF ground radio) and have no trouble building or troubleshooting most anything that smokes when you poke it wrong.  I'm not looking to reinvent the wheel here; I'm just having trouble finding a decent schematic and parts list.  I know I can buy a PS but the good ones are expensive, and I don't need a computer interface, digital controls or anything fancy.  It sounds like a fun project as well.

I have 110/220 60Hz voltage available.

I'm responding because I can see that you've gotten no responses.  Your specification is the problem.  If you want to make a 0-100V "linear" power supply, you would be dissipating a kilowatt at the bottom end- this is not so practical.  Commercial supplies would likely use a multitap transformer with relays to get the dissipation down to something reasonable, < 100 W.  HP made big supplies like this that used SCR's driving the primaries of the main transformer to keep class A type power dissipation down.  A pure linear supply just doesn't make sense.  Think through your needs and refine your spec a bit.  You can buy commercial supplies that can do but they're likely worth the money- its not an easy problem.  Are you sure you need Zero to 100V at 10 amps??
