How do they work working principle IGBT

 

IGBT (Insulated Gate Bipolar Transistor) is a three terminal power switch having high input impedance like PMOSFET and low on-state power loss as in BJT (Bipolar Junction Transistor). 

 

Thus, IGBT is a combined form of best qualities of both BJT and PMOSFET. This is the most popular power switch among the power-electronics engineers and find a great variety of applications.

IGBT is a three-terminal device. The three terminals are Gate (G), Emitter (E) and Collector (C). The circuit symbol of IGBT is shown below.

In this video we take a look at how inverters work. We look at power inverters used in cars and solar power to understand the basics of how they operate.

 We then cover electricity fundamentals, direct current, dc, ac, alternating current, single phase, three phase and split phase, electricity, pulse width modulation, variable speed drives, three phase rectification and more.

  1. IGBT's are for Highvoltage motor control .. MosFets are used in 12 or 24 volt Inverters. IGBT don't have a low ON state .. MosFets do
