So, I have been fiddling around with various ideas recently and have begun work on what seems like a fun project idea, building my own lab bench psu. I know there are a bunch of topics on this already, and I have been trying to read through alot of them (they have been extremely helpful as far as brainstorming goes) however I'm not totally sure what I should work towards for this. I don't necessarily need it to reach 0V, nor do I need it to go much higher than 12V, and about 1A should be plenty. I would rather design the specific circuits myself, as this project is aimed at learning, but what I'm not sure about is what I need as far as protection goes. What elements would you recommend for my psu? I want low noise, so no tracking preregulator, but like what elements should I use for protection or other necessary or handy features? I've seen designs discussed ranging from little more than an lm317 circu it to circuits whose designs are even more impressive than even commercial PSUs, and am just unsure what I really need for my design.
Thanks,
Daniel
