Some Circuit of SMPS, Power Supply, Switch Mode Power Supply are here.
The documentation may not be perfect. Use it for study and design your
own. These were made for custom solutions and even as products.
Study these applications at IRF Applications
and ST
Application Segments. One device used is SG3524.

This is a Regulated 0-30 V DC Power Supply manufactured by me in small
numbers, 0-30V 5A and 5V -5A. It had a Switching Preregulator. This
keeps the Vce across Transistor Bank at the Back of Instrument, at the
lowest possible level, in order to keep them Cool. When Vce and Ic both
are more in a Power transistor it will get heated more, then the
efficiency of power supply is low.
The Output had both Constant Current Control and Constant Voltage
Control. The CC control is also a Short circuit protection. The
Output was protected from outside voltages damaging output circuits
even when equipment is switched off. The back panel is a finned
anodized black aluminum heat sink with many transistors.
I looked for the circuits to scan them, i could not find it. I
made-n-sold quite a few of them years ago. All of them work well even
today as i over-rated most components. The cabinet was Steel for
EMI-RFI Immunity, it was painted with Stipple Matt Powder Coating, the
Cabinet maker had just learnt to give such a finish to his boxes.
