IGBT is a three-terminal device i.e. Gate, Drain and Source.
It is the combination of MOSFET and BJT.
IGBT is preferred for making Variable frequency drives (VFD).
This is because IGBT provides a high switching speed necessary for PWM VFD operation.
IGBTs are capable of switching on and off several thousand times a second.
A VFD IGBT can turn on in less than 400 ns and off in approximately 500 ns.
