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??
