Igbt breakdown
Web6 mrt. 2007 · The "MOSFET driving BIPOLAR" tale is only a popular way of explaining IGBT behaviour to straight people. An IGBT is a device having a single die and an unique structure which combines the advantages of MOS "channel" effect and bipolar "charge storage" effect. The absence of second breakdown is a consequences of this combination. Webvoltage is driven to a high value by the inductor as the IGBT attempts to interrupt current. Because the anode voltage is not externally clamped, the IGBT experiences avalanche sustain- ing voltage breakdown. For most of the results shown in this work, the IGBT avalanches for a period of time before it actu- ally fails.
