The term IGBT full form Insulated Gate Bipolar Transistor is a solid state device. It is introduced on the 1980s. A power transistor characteristics of both MOSFET as well as BJT are used in IGBT. So it makes used advantages of both power MOSFET and BJT, the IGBT has been introduced. IGBT can be used much more application like electric cars, digital stereo power amplifier, SMPS, UPS, PWM, home application and uses in many more power circuits. IGBT advantages are that it can improve dynamic performance and efficiency.
