I've built such an DCDC-converter
the problem is, that i've destroyed my Output-power-waster (
) with a bit too much voltage and that now I can't test the DCDC anymore :'(
in a few days I will get new parts and then I can tell you what happens when I want to get ~250W from one side and ~0W from the other
the core I use is a ETD 39.
I don't know the frequency the DCDC is running at, i'm about to test the best one ( Startet at 100 KHZ, now its about 50K, i think)
my DCDC has also an input voltage of 11-13.8V
The output is 2x22V atm, i will increase it with another transformer soon.
