Transistors - IGBTs - Modules - VS-GT80DA120U application field and working principle

The VT-GT80DA120U is a 1200V IGBT module, designed for Industrial lighting and Traffic lighting applications. It is designed to be used in high power lighting circuits, particularly in automotive applications, and also has applications in industrial, residential and decorative lighting. The VS-GT80DA120U is a three-phase device, made up of three IGBTs (Insulated Gate Bipolar Transistors), one for each phase.

The operation of IGBTs is based on the controlled opening and closing of a switching element. The IGBTs in the VT-GT80DA120U can be compared to a conventional transistor with a built-in electrostatic gate that can be used to control the on/off state of the device. This electrostatic gate also allows for a lower gate voltage, resulting in lower power dissipation and higher efficiency.

The IGBTs in the VT-GT80DA120U have a built-in shutoff gate, which ensures the IGBT is not fully driven at the turn on of the device. In order to turn on the IGBT, a positive gate voltage must be fed to the module, which will cause the shutoff gate to open and the IGBT to be conductive. Also, as the reverse voltage across the IGBT reaches a certain level, the module will be turned off. This shutdown level is adjustable and can be set depending on the application needs.

The VS-GT80DA120U uses a soft-switching technique by using the combination of Turn-On and Turn-Off gate voltages. This allows for a greater efficiency of the device, since the transitions from “on” to “off” are smoother, resulting in less power dissipation and higher efficiency. The modules also feature a Built-in anti-parallel diode, which protects the module from reverse voltages.

The VS-GT80DA120U has an output power of 80A, a maximum voltage of 1200V, and a minimum voltage of 900V. The module is suitable for high current, low noise applications and is rated for up to 2800Vrms input voltage. The module can operate at a maximum frequency of 18 kHz and features a wide temperature range of -40°C to +125°C.

In terms of its applications, the VT-GT80DA120U is ideal for Industrial lighting and Traffic lighting circuits. As the module helps maintain a low level of power dissipation and is highly efficient, this makes it suitable for applications such as industrial and commercial lighting, railway signals, and automotive lighting. The module is also ideal for residential, decorative and traffic lighting applications.

The VS-GT80DA120U has been designed for high reliability, with a low failure rate and high operating lifetime. The module is also versatile and can be used in a wide range of applications. It is available in a three-phase configuration, making it easy for engineers to integrate into existing and new designs.

The VT-GT80DA120U is a highly efficient and reliable IGBT module which can be used in a variety of applications. It is designed to reduce power dissipation and provide a smooth transition from on to off, resulting in a higher efficiency and longer lifetime. The module is ideal for high power lighting and traffic applications, both in industrial and residential environments.
