Hello.
I´m build a linear power supply 13.8V / 60A for a transceiver radio.
The common approach will be use common regulators like 7812 or LM317 and a lot of power driver transistors, a big heat sink, big capacitors and of course a big transformer.
I´m just think about if is there some advantage changing ONLY the common regulator for a switched mode design using the same large transformer and same large capacitors.
At this link **broken link removed** on page 27 there´s a circuit that explain exactly what I´m trying to do. Of course, the driver transistor must be replaced for a compatible project amperage (60A).
Is there some advantage doing this? Less power transistors maybe, better regulation...
Thanks.
