According to the requirements of the "Notice on the Nomination of Beijing Science and Technology Awards in 2024", upon application by the project team, the "Development and Application of High-voltage and Large-capacity Flexible DC Core Components" project applied by our company is now publicized (see the attached materials for the publicity).

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;

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

"Inverter World": Filling the domestic IGBT gap! Another Chinese business card is born

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, the rapid development of new energy markets such as electric vehicles, electrochemical energy storage, photovoltaics and wind power has greatly increased the market demand for power devices. In particular, the rise of electric vehicles has caused IGBT to be in a state of tight supply all year round, and there is no sign of relief in the next few years. At this time, SiC devices have also taken advantage of the situation and started the road to penetration in the automotive

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.

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,
