Hi Dick, I dont have anything in electronic form but I sure there is a lot.
Do a Google search for "electronic fuse". There have certainly been ideas in
Elektor over the years that would fill your requirement (maybe with scaling
for the current) Maybe a search of the Elektor archive would be fruitful.

Hello all,

after 2 days of searching the internet and a lot of magazines here,
I still haven't found any (simple) design for a powersupply in the 50-100V
range.

I want to run something with an fixed voltage between 50 to 100 Volt,
depending
on what transformer configuration I'm using.
However, I want to have some sort of automatic protection circuit against
to high currents that switch of the supply when current gets to high.
Yeah, I know, a normal fuse will work, but I do not want to spend a bag off
fuses while experimenting.

It will be a unit that requires an input of 50-100V AC, giving a fixed DC
value out.
(that gives me the possibility to use various transformers)

So, any hints suggestions or maybe website's will be welcome.

Dick, pa4vhf
