900V DC bus with 1200V SIC module

Duclair

I am designing a three phase rectifier with the requirement to reach 900V on the DC Bus. As I can see, most of the tests on the application notes for wolfpack modules are with 800V on the bus, same for some specs on the datasheet. Also, the gate resistor populated by default on wolfspeed gate drivers seem to be 1Ohm, I would like to know if it is required to increase this value for a DC bus of 900V, even if a good DC bus layout is assumed, and that I will include snubber capacitors on the PCB. I would also like to know if some of the reference designs from wolfspeed have been tested at 900V operational, with 1200V modules.
