Hi,
I have Diode Bank of 100nos of Diode (SF4007) are are connected in series. My aim is to test this diode bank on full load. SF4007 has iMax =1A, Peak reverse voltage is 1000V.
This Diode bank is connected to 30Ohm 300W resistance which is again in series. I am giving 100VDC to
Anode of bank and Cathode is connected to 30Ohm 300W resistance and another end of resistance is connected to ground. I am expacting 30V drop across 30Ohm resistance and 70Volt drop across Diode Bank (consists of 100nos x SF4007 diode), so that 1A current can flow. But in actual, its not happening.
I am getting 97V drop across Diode bank and 3 Volt drop across 30Ohm resistance.
Pls. let me know the reason and solution.
Regards
Joshi
