Working Principle

The VS-GT120DA65U is an N-channel IGBT module. It is composed of two parts: the IGBT and the freewheeling diode. The IGBT has an insulated gate and is made up of three electrodes: the emitter, base, and collector. The emitter and collector are connected to an external power circuit and the base is connected to a gate voltage. When a suitable amount of voltage is applied to the IGBT, electrons flow from the emitter to the collector, thus creating a current. The freewheeling diode is a diode connected in parallel with the IGBT, opposite the polarity. When the IGBT is turned off, the diode functions as a short-circuit, conducting current in the opposite direction and dissipating the stored energy. This prevents the voltage from increasing and helps to protect the IGBT from damage.

Conclusion

The VS-GT120DA65U is a high-performance IGBT module that provides a high power density and switching performance. It is suitable for a range of applications, including motor control, welding, AC/DC and DC/DC power conversion, and high frequency switching. It features a high maximum junction temperature range and low on-state losses, providing high efficiency and reduced power consumption. It can also be used in a variety of industrial applications, making it a versatile IGBT module. The working principle utilizes both an IGBT and a freewheeling diode, ensuring high current flows while protecting the device from damage.
