In Reply to: RE: What does "ringing" look like on PSUD simulation? posted by DAK on February 11, 2017 at 11:15:53
If you google PSUD 2 you will find all kinds of tutorials on how to use the program. I don't currently have PSUD loaded on this computer (new computer)
so I can't produce a ringing example for you. however, basically if you use
the current step function the line should drop down and then go flat or maybe jump up a bit. but if the line drops then jumps back up then down many times until it flattens out, that is ringing.

OK, for a step load what are the considerations for inputting the step load? For example my total load is about 220ma. What do you input for a step load under those conditions?
Go 200ma. Stepped to 240ma. Then Look at voltage at c1, c2,c3 etc... Overshoot prior to settling is essentially a form of ringing. A generality would be the more series dcr in a supply the leas likely to ring(in audio band)/ JH
