Ugly DC-DC SMPS
 
Hi Dears

This is my new DC-DC smps. 13,8V input, +35V/-35V output, no more strong, maybe a 200 watts.

wow... that transformer is really BIG! :scratch:
Diodes are small... :hot: I don't know... I would prefer T0220 package and heat-sink...

SMPS schematics
 
Hi friends

The schematics is the same of Rod Elliott SMPS, ok.

Yes, the core is so big, it's only that I have, about UF diodes, it's so small, but It's a prototype only to play so much. I prefer to build AC-DC smps, my last is 13.8VDC/100A (127/220VAC).

Regards

Sandro
