Switch Mode Power supply, switching Mode Power supply, and switching converter are high-frequency electrical energy conversion devices, and are a kind of power supply unit. Its function is to convert a bit of voltage through different forms of architecture into the voltage or current required by the user. The input of the switching power supply is mostly AC or DC power supply, while the output is mostly DC power supply equipment, such as personal computer, switching power supply is to carry out the voltage and current conversion between the two. Switch power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, and other fields. Switching power supply is different from linear power supply. The switching transistors used in switching power supply are mostly switched between full-open mode and full-closed mode. Both of these models have the characteristics of low dissipation. Switching between switches has a high dissipation, but a short time, so it saves energy. The switching power supply consists of a main circuit, control circuit, detection circuit and auxiliary circuit. The power electronic devices used in switching power supply are mainly diode, IGBT, MOSFET, and transformer.

IGBT开关过程

IGBT的开关过程主要是由栅极电压VGE控制的，由于栅极和发射极之间存在着寄生电容，因此IGBT的开通与关断就相当于对CGE进行充电与放电。假设IGBT初始状态为关断状态，即VGE为负压VGC-，后级输出为阻感性负载，带有续流二极管。

What is IGBT? What is Its Working Principle? What are Its Advantages?

When we give G a very low power frequency, the IGBT will cut off, which is equivalent to a switch being disconnected. When we give G a very high power frequency, the MOS lead is turned on, and then the CE pole of the transistor forms a current, and the IGBT conducts. This is the principle of IGBT.
