In addition, IGBTs have a lower on-state voltage drop and are capable of blocking higher voltages. The IGBT, as a first approximation, can be modeled as a PNP transistor …
Web24 okt. 2013 · There is no reason you need a FET to drive the NPN inside the IGBT for you. You can modify the circuit a bit to drive a NPN directly. Whatever you use for the switch, it should be rated for fairly high voltage, like a few 100 V, or you need to clamp the kick back voltage somehow. Added: WebThe Insulated Gate Bipolar Transistor (IGBT) is a minority-carrier device with high input impedance and large bipolar current-carrying capability. Many designers view IGBT as a device with MOS input characteristics and bipolar output characteristic that is a voltage-controlled bipolar device.
