"WebHowever, it should be remembered that IGBT tail current losses are completely independent of the value of the gate resistor. It can be noted that in figure 6 the dV/dt and tail current losses are around the same with a gate resistance of 47 Ω. Even though the tail current is constant, the losses in a system are often predominantly due to dV/dt, " - Igbt snubber resistance
