IGBT(Insulated Gate Bipolar Transistor), It is composed of BJT(bipolar triode) and MOS(insulated gate type field effect tube), which has the advantages of high input impedance of MOSFET and low on-voltage drop of GTR.
IGBT is the core device of energy conversion and transmission, commonly known as the \"CPU\" of power electronic devices. As a national strategic emerging industry, it is widely used in rail transit, smart grid, aerospace, electric vehicles and new energy equipment.
