As one of the core power switching devices, the insulated gate bipolar transistor (IGBT) combines the advantages of the metal-oxide semiconductor field-effect transistor (MOSFET) and the bipolar junction transistor (BJT), and has been widely used in medium and high power power electronic devices in the fields of new energy vehicles, smart grids, rail transportation, industrial control, communication power supplies, consumer electronics, etc.

In recent years, with the continuous improvement of IGBT design technology and the introduction of new materials and new processes, the energy saving, heat dissipation, reliability and stability of IGBT modules have become increasingly prominent, making them a core component that has attracted much attention. Data shows that by 2022, the global IGBT market size has reached US$12.37 billion, and new energy applications represented by electric vehicles have become the main growth point of the IGBT

The national core journal "Ship Engineering" published a special article "Technical Application of a Certain Type of Marine Solid-State DC Circuit Breaker", which introduced the working principle and development status of marine DC circuit breakers at home and abroad. The article takes SUN.KING's marine solid-state DC circuit breaker as the research object, and explains the outstanding achievements of SUN.KING in the cutting-edge technological innovation and exploration in this field;

Today, the electric vehicle industry has become a fertile ground for innovation. With the emergence of the 800V voltage platform, some new trends have emerged in power transmission: the all-in-one integrated system's battery chassis integration (CTC) has greatly simplified the battery structure, optimizing vehicle space while maximizing performance; the miniaturization, high power and high voltage of the inverter have also made the laminated busbar (Laminated Busbar) with low inductance,

Under the "dual carbon" goal, as new energy continues to move towards the main power source, long-distance transmission of large-scale new energy bases has become a top priority in the country's energy structure transformation process. The characteristics of the power grids at the sending and receiving ends determine that the use of flexible transmission technology is essential.

On July 4, engineers Yang Yinhe and Zhao Weiting from Wuxi SUN.KIN Power Capacitor Co., Ltd. completed their mission and returned from the Baihetan-Jiangsu project site, a strategic artery of the country's "West-to-East Power Transmission" strategy. For more than a month, they stayed at the construction site in western Sichuan until the power transmission project was officially put into production. "Overcoming the impact of the epidemic, the company successfully completed the construction of sup
