The current on the primary was arround 120A, but I used 50% duty cicle interrupter, that killed the bridge after running more than 15 minutes at 127 Mains (with 220 mains, it kill less than 1 minute)
I am making another interrupter, based on eastern voltage control interrupter, that will make some arround 120BPS, that will be better for the igbt's.
If you see, even running at Mp3 Modulated is running good. without many distortions.
OMG, why do you using so high interrupting f ??
i believe with 1KHz will be longer spark :)
but well done, do you ever kill bridge by using so high interrupting F, and how lot current in primary?? (pulsed)
