| May 23, 2016 at 17:59 | comment | added | dim | @AndrewMorton I know. I even designed a circuit to dynamically configure the secondaries either in series (18V@4A), parallel (36V@2A) or a kind of x3 configuration ([email protected]) to make the most out of the transformer. But I don't want to use multiple transformers, or an impossible to source multitap one, so in the worst case I still have 72W to dissipate. | |

| May 23, 2016 at 9:30 | comment | added | dim | I planned to make a pre-regulator with a buck, and then a linear regulation. The linear part simulates very well, but in the worst case, the main fet has to dissipate about 70W. That's way too much. There has to be some efficient pre-regulation. | |
