TLDR
The insulated gate bipolar transistor (hereinafter referred to as IGBT) is a composite device of MOSFET and GTR. It is an ideal switch device to replace GTR, which is widely used at present with its ability to turn off, and it’s also widely used in all kinds of solid-state power supply. The drive circuit is very important to IGBT, but improper control may cause damage, such as IGB damage due to overcurrent, and affects the performance of the whole machine.via the TL;DR App
