The working principle of the APTGLQ400A120T6G IGBT module is based on the principle of insulated gate bipolar transistor (IGBT). The IGBT is a three terminal device, which consists of two p-type layers and one n-type layer. It is an enhanced version of MOSFET, which is more suitable for power switching applications. When a voltage is applied to the gate, it will induce an electric field that will cause the electrons to flow from the source to the drain. As electrons flow, a current will be generated, causing the output voltage to change. In addition, the IGBT module can be used to reverse the current direction by adjusting the gate voltage accordingly.

In conclusion, the APTGLQ400A120T6G IGBT module offers a wide range of application fields and a high level of efficiency. It is suitable for a variety of power switching applications, such as welding and uninterruptible power supplies (UPS) systems.
