An Insulated Gate Bipolar Transistor (IGBT) is a key part of what makes up a VFD (Variable Frequency Drive). In the event that you separate a VFD, one simple approach to break down it is to consider it in three principle parts: the scaffold converter, DC join, and what we will discuss today, the inverter. An IGBT is the inverter component in a VFD, beating voltage quicker than we can even squint.
