I have been moving forward with my Bench PSU project and had a look today at increasing its current output. My design (still in breadboard stage) uses LM317 and LM337 regulators so it can provide about 1.5 amp. I was looking at increasing this to around 3 amp.
One option I have looked at is using the same regulators with the addition of pass through "power" transistors. The other option is to use higher rated regulators. What are the pros and cons of each approach.
Thanks for any help given, Paul
