High voltage, high current super regulator, possible group buy

[peranders]

I have set up a wiki page for a possible interest.

Please sign up at the wiki page. No commitments, it's only the the interst. Specifications are not frozen yet so there is still time for wishing.

I added myself to the list

Cool.

Jens, I've just checked what you wanted, 0-100 V out and as a lab PS. This is wishful think I'll imagine. The goal is a fixed regulator with a fair amount of protection. As a lab PS you must add stuff because you have an unknown load.

Reckon this is quite interesting project so another sign-up.

After trying your & the ALW SR's in preamps & phono's etc I'm thinking it would be interesting to try something similar with my NAP250 boards to see what results.

Probably a column of smoke & some charred remains knowing me but that's half the fun.

Just checked the wiki. You can always dream but 600 volts, 3 A! That's dreaming, at least in this project.

This circuit can be modified to suit high current high voltage regulator. Except that the heat may be quite high!

 

[morpheus82]

interesting...but what about the price?

 

[peranders]

The pcb will probably be rather small, affordable....

 

[peranders]

You can always dream but the wish list is starting to get extreme

650 volts, 20 A, + goodies

I'm still into a few amperes and max approx. 100 volts. Somehow I don't feel that a 50 MHz regulator should be in a tube amp.

Just because I like dragging up 2 1/2 year old threads...

There is a high voltage, high current reg for you you look at. It is not quite "super regulator" because it lacks a pre regulator. But it is all discrete, and it is high performance.

An externally hosted image should be here but it was not working when we last tested it.

Added my name on the wiki page. Just curious if it really makes a difference using this regulator to an amp compared to a regular power supply?

The AMB project is a conventional regulator, rather good as far as I can see.

When it comes to my project it will have to wait a bit longer. The interest isn't overwhelming.

I'll guess noone knows since no such regulator has been designed yet.
