IGBT Full Form, Symbol, Construction, Working and Applications

An Insulated Gate Bipolar Transistor in short IGBT is a three-terminal semiconductor device it is a hybrid of MOSFET and BJT for high efficiency and fast switching. The power BJT has the advantage of low on state power dissipation, but it cannot be switched at faster rates due to longer turn-off time, whereas MOSFETs have […]
