Looking for 30V 5A schematic

Kleinstein:
The combined SMPS + linear supplies usually have the SMPS tracking the output plus a few volts so the linear stage has some reserve to work with and also to allow some drop in a filtering stage between the two.

Hi! Hope you don't mind it, when I pull this thread up again.

Just in case you're still searching for a power supply with tracking SMPS preregulator you might be interested in this design: https://www.mikrocontroller.net/topic/396405
In particular the final plans: https://www.mikrocontroller.net/attachment/298951/Labornetzteil-Schaltplaene-final.pdf
PM me if you want to have the EAGLE Files (PCB and Schematic)

Although it is designed for 24V and 2A it should be possible to upgrade it to 30V 5A.
I use it nearly every day and I'm quite happy with it.

Regards
Luca E.
