Hello Folks,
While looking for a variable bench psu design, I came across two designs ; adesign from Everyday Practical Electronics Magazine. (Jan’02), and one from KD1JV, Steve” melt solder” webber .
Both these design seem to suit my requirements, 15+V, Upto an Amp, with cc-cv modes for those gotcha! Moments ( some casual tinkering around the bench, testing out radios and digital circuits) . I do have a kit on hand based on the lm723 but after some reading around I figured that the current limiting feature maynot be the best on the 723. Therefore, im leaning towards a discrete solution involving opamps.
Im looking for feedback on these circuits, any recommended modifications or any noticiable flaws. My plan is to build one and replicate them if succesful in the local radio club.
TIA!
