I was wondering, is there a possibility to avoid parasitic turn-on without a negative voltage supply?

Good morning,

driving the SiC MOSFET with VGS,off = 0V and a 1EDI EiceDRIVER Compact with active Miller clamp will avoid a parasitic turn on.
Moreover, by eliminating the negative-voltage driving, the power losses of the driving stage can be reduced (~30% less, assuming VGS,off=-3V and VGS,on=20V) or for the same power losses, the VGS,on can be increased.
