The most basic function of an IGBT is the fastest possible switching of electric currents, thus achieving the lowest possible switching losses. As the name “Insulated Gate Bipolar Transistor” reveals, an IGBT is a bipolar transistor with an isolated gate structure; the gate itself is basically a MOSFET. Therefore, the IGBT combines the advan-

Figure 1 - Silicon cross-section of a planar “punch-through” IGBT and of a trench IGBT. Trench IGBTs have higher levels of electron injection that reduce the voltage drop across the IGBT. The cross-section of an IGBT is very similar to that of a MOSFET but the
The 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. To make use of the advantages of both Power
