I've been looking ahead in my textbooks and reading some stuff online, and there's some things I'd like to know about DC power supplies.
The DC power supply we have at school has 3 independent outputs, 2 variable and one fixed. How would they be isolated from each other like that? Triple-secondary transformer? Seems pretty complicated, which might be why stuff like that is so expensive. Would it be possible to do it with only one secondary?
Second, the supply has a pair of push buttons in front of it that can hook the two variable supplies up in series or parallel, in a master-slave configuration; the voltage knob for the master controls both supplies. The one (naive) idea I had was that the two regulator's ground pins where hooked to the same potentiometer, but that would
I've done a little googling for schematics, but most of the schematics have been for basic supplies without these features.
