High dv/dt

WebIt 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, because the value of the gate resistance is often too high. In the example of figure 7, the total losses per WebMedium-voltage (e.g., 10 kV rated) silicon carbide (SiC) devices have great potentials in medium-voltage variable speed drives. But their high switching dv/dt can increase the voltage stress on motor windings and cause partial discharges.
