IGBT:
A bipolar transistor with insulated gate electrode (insulated
gate bipolar transistor, IGBT) is a semiconductor that
is increasingly used in power electronics, as the bipolar
transistors offer certain advantages (e.g. good forwarding
characteristics, high blocking voltage, robustness in welding
equipment) and benefits characteristic of a field effect
transistor (control with virtually no power consumption).
Another advantage is a certain degree of resistance to short
circuits, as IGBT limits the load current. IGBTs are a further
development step of the vertical power MOSFETs.
