What is igbt？
An IGBT (Insulated Gate Bipolar Transistor) is a type of transistor commonly used in power electronics. It combines the high input impedance of a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) with the high current-carrying capability and low saturation voltage of a BJT (Bipolar Junction Transistor). This makes it particularly useful for switching applications involving high voltage and current, such as in motor drives, inverters, and power supplies.
IGBTs are often used in systems that need to efficiently switch high power at relatively high speeds. The device is controlled by a gate voltage, similar to MOSFETs, and is designed to handle high power with less loss compared to other transistor types. Some key features of IGBTs are:

GaN-IGBT performs well in high-frequency switching applications and can effectively improve power density and conversion efficiency. Although GaN devices are currently mainly concentrated in low voltage and small current fields, with the advancement of technology, it is expected to be expanded to higher voltage application scenarios in the future, further broadening the application scope of IGBTs.
2. Process optimization and structural improvement
New grooved and flat structures
By introducing new trench and planar structures, the current path inside the IGBT can be optimized, allowing the device to distribute heat more evenly and reduce the formation of local hot spots, thus improving reliability and service life. For example, the use of ultra-fine line width lithography technology and deep groove etching technology can greatly increase the current carrying capacity without increasing the chip area; while the planar structure can achieve lower parasitic parameters through multi-layer metal wiring. Improve dynamic response characteristics.
3D packaging technology
3D packaging technology brings new possibilities to IGBTs. The multi-layer stack structure can not only effectively increase power density, but also reduce the influence of parasitic parameters, thereby improving dynamic response characteristics. In addition, 3D packaging can also integrate more functional modules, such as drive circuits, protection circuits, etc., to form an integrated solution, simplify system design and reduce costs. Especially for high power density application scenarios, such as electric vehicles, wind power generation, etc., 3D packaging technology will play an important role.
3. Intelligent and modular design

Intelligence is one of the important directions for IGBT development in the future. The built-in sensor can monitor the working status of the IGBT in real time, including temperature, current, voltage and other parameters, and transmit the data to the control system through the communication interface. This self-diagnosis function can not only detect potential faults in time, but also make dynamic adjustments based on actual operating conditions to ensure the safety and stability of the system. For example, in the field of industrial automation, smart IGBT modules can work together with other equipment to achieve predictive maintenance and improve production efficiency.
Modularity and standardization
The modular design allows users to flexibly combine IGBT units of different specifications according to actual needs, simplifying the installation process and shortening the development cycle. At the same time, standardized design specifications also help improve interchangeability and compatibility, facilitating mass production and promotion. Especially in distributed energy systems, small and modular IGBT solutions are becoming more and more popular, bringing new growth points to the market.

The new generation of drive circuit adopts advanced topology structure and algorithm optimization, which can accurately control the switching time of IGBT and reduce oscillation and overshoot. In addition, some drivers also integrate functions such as isolation transformers and negative feedback loops, which further improve the anti-interference ability and reliability of the system.
5. Improved reliability and security
Fault diagnosis and protection mechanism
In order to ensure the normal operation of IGBT under complex working conditions, manufacturers have strengthened research on fault diagnosis and protection mechanisms. For example, through the built-in temperature sensor and current detection circuit, the working status of the IGBT can be monitored in real time. Once an abnormality is detected, protective measures, such as current limiting and shutdown, are immediately triggered. In addition, some high-end products also support remote monitoring and data analysis, helping users better understand the health status of their equipment and prevent potential risks in advance.
