Hello Everybody!!
I have a chance to get some very high end IGBT modules for a very low price. Right now im trying to get a case of 600A 400A Powerex modules. These are a high end module that is close to $300 each from a supplier. I am looking for people to fill space for 4 or 5 more modules. O, and the price. $20 each!!!!! You should be able to put 2 of these modules together and create a 500A controller very easily. All you need to do is run 3 bus bars down connecting the same terminals together and add a capacitor bank to the B+ and B- terminals. These are 2 pack IGBT's so you don't need a separate one for a diode, you can just tie the gate of the second half low and use its diode. You could push 600 through 2 modules if you keep them both the same temp. You will need to mount them close together on a thick piece of aluminum.
Here is the spec sheet.
