WebMay 27, 2024 · Keilau, I think the purpose of the opamp in the schematic you show for "servo, rectifier, filter power supply board" is to take the ripple and noise from the output of the power supply, invert it, and feed it back into the lm317/337, thereby cancelling the ripple and noise on the output. Hence the "servo" in the title. WebAug 23, 2024 · The LM317 acts as a sort of constant current generator that has a power output and it keeps a certain current flowing in the two resistors and that is what holds the output voltage constant. There is a slight error current but it is small.
