| Apr 2, 2023 at 12:47 | comment | added | Infernoman | @greybeard With my limited knowledge I don't think I would be able to build an SMPS. But if you can suggest a basic SMPS circuit I'd be willing to give it a try. Tomorrow I'll be separating the secondaries, and adding a second rectifier then I'll post the results. | |

I think Autistic's advice the 2nd best: Lash up a basic rectifier circuit and see how far that gets you (Don't let the open circuit voltage irritate you). If you can't separate the secondary into independent windings, you aren't screwed for good: make the centre tag your GND, connect the AC sides of both bridges, but use the + terminals of each, only, leaving the - unconnected. In any case, go separate paths & connect as far to the load as feasible for better current split. | |
