It would be really great if your individual circuits could be bread boarded as you went so all of your info could be visualized on a scope.

Always enjoy your video's...Tnx..Have the same power supply board from several years ago. Waiting to see what you final version looks like on the Heat sink.. Keep up the good work...

There’s a trade off with using the current limiter to reduce the input to the voltage controller: over-current transient is higher and lasts longer when the output gets overloaded/shorted. Professional designs usually run the two control loops in parallel, so that either can “turn down” the pass element.

The current limiter is not a comparator I don’t think. It is an outer control loop closed around the voltage control. It should regulate any current set point although rather poorly since there’s lots of delay in the inner (voltage) loop. It has lots of gain - two op-amp’s worth - so it can be quite precise in current regulation once things settle down, but the transients are a sight to behold on that thing I bet.

Great teaching skills, Sir. I'm a teacher (operational research, data science) and I do all my courses on-line due to pandemic. I used to proof some equations and clarify concepts on whiteboard in class, which is impossible now. I'm impressed by your "camera" which zooms on your hand writing perfectly. Could you share some info on your infrastructure ? br from Poland

You know, you're pretty good at this teaching thing. The proper measure of information at each
