You need to change it before any tests, couse bad driver can make short circuit on your mosfets. You need to change as well new resistors on mosfets gates.
I am planning after second blown up changed:
-power board (first was custom made) I want to put double 15 microns but maybe should be double 30 microns thick - please advice
-rezystors R17, R36-45 (20 Ohm) diode D6
- mic4451 U7 i U6 HCPL-4504
for sure c21, c20, R16, C18 and Q1
but ...
Ducan have you found what caused your controler failed at first place? Have you put 170A or 130A power mosfets? I asking couse I have cooked mosfets as well and I am not sure for 100% why and what is wrong or could be wrong, please help anyone.
