If i knew then, what i know now i probably would have done so. My problem now is that I probably doubled my budget and cant afford to spend much more on this. I probably got to eat cheap the couple of days just to get another UHU controller chip!
It has been stated the it should be possible with up to 150 v on the regular UHU with the IRFP260 transistors. These are rated 200V so 140 which I'm aiming for should not be a problem, i think . . .
I know that the reason for the HP UHU design was problems with handeling powers excess of 500w which I'm not even nearing. I have to try and make it works . . . .
I was hoping someone had done this before, running the regular UHU design with excess of 100V.
