Web/dt into the gate emitter capacitance Cge and through the gate resistor to the driver circuit, see Figure 2. The resulting voltage V ge on the gate can be sufficient to turn the IGBT on again with possible shoot-through and damage. Driving the gate to a negative voltage mitigates this effect. WebAug 12, 2024 · This is sometimes added if a specific instance is susceptible to dv/dt turn-on (layout, lower current drive, installation). A collector-gate current, via the parasitic capacitance: Ccg flows at every switching event. If the gatedrive does not have enough drive capability to absorb this charge then the IGBT can inadvertently turn on. By adding a ...
