WebIGBT-basic know-how To improve the switching performance of an IGBT, auxiliary emitters are commonly used. This connection reduces the influence of stray inductances within the gate circuit. What has become a de-facto standard in power mod-ules, has also recently reached discrete components in the newly designed TO247-4. Figure 4 depicts the ... WebThe dynamic IGBT performance can be adjusted by the value of the gate resistor. The gate resistor influences the IGBT switching time, switching losses, reverse bias safe operating area (RBSOA), short-circuit safe operating area (SCSOA), EMI, dv/dt, di/dt and reverse recovery current of the free- wheeling diode.
