In this training, we will see how Infineon’s two-level slew-rate control (or 2L-SRC) gate driver IC can help overcome gate resistance dimensioning trade-offs in order to obtain reduced switching losses.
We will also see an example of gate resistor dimensioning, with an under-five V/ns voltage slope target, as usually seen in drive applications.
