breeding ore brooding,- what ever -
my egghead cam to the fallowing solution:
I surch for a fault in the circuit since one year and I can not find it. right ?
Question: are I to stupid to find it ore do I surch at the wrong place ??
until now, I was fallowing the answer of : I am to stupid !
from now, my EGG says, - I will fallowing the way of : I do surch at the wrong place
so, stoping to protect the MOSFET ore IGBT from EMF`s, - GO TO SURCH ON THE LEFTOVER PLACE ON SUCH A BUG !!!!
as this parts al have a GATE, I started thinking as I may do something wrong at this side !!
and I cam to the point, as I do not GOOD, FAST, CLEAR enough switching the gate !!!!!
I think I need to use a GATE- DRIVER to not burning the Semiconductor ( MOSFET / IGBT ) by the load wich is a bit heavy in my case of the 400 Volts and the 2 ore 4 ore 6 uF. capacitors
so, soon I will place a order by my suplier for some MOSFET DRIVER like : IR 2101 , ore MAX 626 , ore MAX 627 , ore NJM 3548 .
I guess, I need a device wich is switching the Gate in a Time of maximal let say 0.2 Micro Seconds ore so, best would be by 20 Nano seconds I guess....
not shure it will work, but beat is giving this way a try....
