IGBT(insulated gate bipolar transistor) is a compound fully controlled voltage-driven power semiconductor device composed of BJT(bipolar junction transistor) and MOS(insulated gate field effect tube), which has the characteristics of self-turn-off. Simply put, it is an on-off switch, IGBT has no function of amplifying voltage, it can be seen as a wire when it is on, and it is open when it is off. IGBT combines the advantages of both BJT and MOSFET devices, such as low drive power and low saturation voltage.
IGBT module is a modular semiconductor product made of IGBT and FWD (continuous current diode chip) through a specific circuit bridge package, which has the characteristics of energy saving, easy installation and maintenance, and stable heat dissipation.
IGBT is the core device of energy conversion and transmission, and is the \"CPU\" of power electronic devices. Using IGBT for power conversion can improve the efficiency and quality of power consumption, and has the characteristics of high efficiency, energy saving and green environmental protection. It is a key supporting technology to solve the problem of energy shortage and reduce carbon emissions.
IGBT is a Darlington composite device with GTR as the leading component and MOSFET as the driving component. There are three electrodes on the outside, which are G-gate, C-collector and E-emitter.
