Current control.

What schematics of serwer PSU's with power over 800W are available?

 

[Doctore]

I was thinking about building DIY PSU, I find something easy:

And I want to use parts(eg. transformer) from PSU, If I want to get this 3-50V, I need to use transformer from 50V PSU?

I cannot understand the operation of the secondary rectifier comprising D5, D5', D6, D6' in the above schematic.

What transformer or you talking about?
There is no input transformer in that design.
It runs off mains voltage directly

To rectify the AC

I'm talking about "power transformer"/"DC transformer" that eat 350VDC switched/controlled by SMPS fet.

Where are replies?
I'm talking about part that is signed on this diy supply as a "Tr1"
And If I want to build my 3-50VDC DIY SMPS, I should use transformer wired to work in 50VDC?

I was like you until I realised the bottom pair are for maintaining the current flow through L1.

D5, D5', D6, D6' are used to keep right polarisation and to rectify output voltage >DC< not AC.
