WebThe choice of gate resistor has a significant effect on the switching delay time. In general, the higher the resistor, the longer the delay time. It is recommended to measure the delay time with a dedicated gate resistor in the application. Figure 4 and Figure 5 show the typical graphs of switching time versus gate resistor. WebThroughout the dV/dt period, the voltage across the gate resistor is equal to the Miller voltage (Vgm), and for a short time the power switch operates in linear mode. In this example, with a STGP10N50 IGBT (Crss≈ 40pF) the dV/dt will be around 7.5V/ µs.
