The role of IGBT modules

The full name of IGBT is Insulated Gate Bipolar Transistor. Its functions are as follows:

1. From a functional point of view, IGBT is a circuit switch, the advantage is that it is controlled by voltage, the saturation voltage drop is small, and the withstand voltage is high. Used in strong currents with voltages of tens to hundreds of volts and currents of tens to hundreds of amperes. And IGBT does not use mechanical buttons, it is controlled by a computer.

2. With the switch of IGBT, a type of circuit can be designed: controlling the IGBT through a computer, turning the AC power on the power supply side into DC power of a given voltage, or turning various kinds of power into AC power of the required frequency, Load usage. Such circuits are collectively referred to as converters.

3. The GBT module has the characteristics of energy saving, convenient installation and maintenance, and stable heat dissipation. At present, most of the products sold on the market are such modular products. Generally speaking, the IGBT also refers to the IGBT module. With the advancement of concepts such as energy saving and environmental protection, this product will become more and more common in the market.

4. IGBT is the core device for energy conversion and transmission, commonly known as the "CPU" of power electronic devices. As a national strategic emerging industry, it is widely used in the fields of rail transit, smart grid, aerospace, electric vehicles and new energy equipment.
