I think it would not be best to drive 2 with one driver,and 1 with another driver. I think the 1 would turn on faster maybe because of less gate charge? I don't know about that. One driver would be putting out more current than the other. Hmm... I don't know. I just think that symmetry is really important at very high currents. How about 4 igbts! ya! You want the other competitors to just quit and go home, you don't want it close.
