Hi all, this is my first actual post here.
Been reading for quite a while, great information here
I'm looking to build an adjustable power supply with some DC power supplies, I have 2x 12v 32amp supplies of which I primarily require 20v with 5amp output. I've seen designs for voltage boost (12v to 24v) but to only around 2/300ma which isn't very useful.
In consideration I though placing the two supplies in series to create 24v 32amp. However I need some way to have adjustable voltage, the greater the range of the adjustability the better for the bench supply. Plus current limiting is very important, there is 32amp available, and would like to make the use of as much of that as possible, however 0-5amp adjustability is vital with precision. Each supply also has a 5v 0.6amp output to maybe drive control circuitry. Each supply does have short circuit protection, however I would like to implement this into the design also similar to the LM723 designs.
I would appreciate any input, I have an Arduino for means of programming a PIC, although would prefer not to have to go through that procedure Linear maybe?
Thanks for reading.
