Party with me.
I am that happy I must tell somebody:
The NSV is now totally rebuild.
I must say something my former L1 where that good as I thought. We made some more measurement and we measured a really HIGH ripple current of 0,5V [img]redface.gif[/img]
So I called FPS and asked for a new L1 but as I knew the didn't have them and they said that they also will not support the old NSV 56 any more. So I asked for a not working NSV and they send me one.
It was a little bit burned [img]smile.gif[/img]
But we were really amazed that only the potent and the soldering of the L1 were burned so the problem was not the L1 it was the way how they soldered it in. It must have been unclean there ore they used a wrong flux.
So The L1 was still working and we did some measurement with it and found out that it had a much higher inductance as we thought as it had to have so I made a new one.
And now there is silence only L2 is making some noise.
The ripple current is at a really low level.
And now I hope the nightmare is at an end and I can work without problems the next weeks. Okay I also have a new problem but it's just a broken wire at the control console.
Easy to fix.
