From my side, just launched in production my driver board :
I designed this board for direct mount on these standard 6 pack igbt module :
This IGBT module was sleeping in a drawer, I will use it for my 144V/400A DC controller for my car conversion (2 agnis 95R motor in series). A transistor is dead on this module but I will just use 4 transistors, I will parallelize 2 pairs of them to better divide the current and thermal effect on each transistor.
The good thing is that this universal driver board will permits AC configuration in future
This IGBT module is a 600V/450A @80°c model, from danfoss. With 2 half-bridge parallelized for DC brushed configuration, I can go up to 900A if needed
Now I need to develop the control board, and the DC capacitor bank board with busbar connection :/
For the capacitors I will use ten of these :

I hope it will be enough !
