www.ixys.comThe 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

The output of leg A is equal and opposite to the output of leg B. The output voltage is determined by comparing the control signal,
Bipolar Transistor
www.chu.berkeley.edubipolar transistor models are introduced, i.e. , Ebers–Moll model, small-signal model, and charge control model. Each model has its own areas of applications. he bipolar junction transistor or BJT was invented in 1948 at Bell Telephone Laboratories, New Jersey, USA. It was the first mass produced transistor,
