Hi all, I'm starting out and would like to build myself a variable bench power supply that keeps current to a maximum of 1A and voltages anywhere between 0V and 30V. I have looked at many schematics but I'm not 100% sure of which to go by. I have no problem with the transformer/rectification and smoothing processes of the design but I'm not sure how to set up the voltage regulator (LM317).
If anyone can help me out with an easy to follow schematic or help me figure it out I would much appreciate it, especially help with what kind of values for resistors/caps/pots I have to use, that's what I need most help with. The basic flow diagram I imagine is just:
AC Input -> Step-down Transformer -> Diode Bridge Rectification -> Smoothing Capacitors -> Voltage Regulation and Safety Fuses...?
Thank you,
JP
