On September 24, 2025, PCIM Asia 2025, the Shanghai International Exhibition and Conference for Power Electronics, Intelligent Motion, Renewable Energy, and Energy Management, opened grandly in Shanghai. As the most influential power semiconductor event in the Asia-Pacific region, the exhibition brought together leading global companies and top industry experts. Sun.King Technology, under the theme of “Innovation-Driven, Green Future”, showcased its latest R&D achievements and a wide range of self-developed core products, highlighting its technological strength and innovation capabilities in the fields of power semiconductors and power electronics.

During the exhibition, Sun.King Semiconductor presented a comprehensive product portfolio covering IGBT and SiC chips and modules. These included HEEV-packaged SiC modules for new energy vehicles and ED-packaged IGBT modules for industrial control, all developed to address the industry’s growing demand for efficiency, reliability, and miniaturization. The booth quickly became one of the main attractions, drawing dozens of inquiries from new energy vehicle manufacturers, energy storage companies, and industrial equipment makers eager to learn more about product performance and potential cooperation.

At the concurrent conference, Mr. Bo Wang, Deputy Manager of the Marketing Department at Sun.King Semiconductor, delivered a speech titled “Application Analysis of the New Generation i23 Series IGBT in the New Energy Sector.” He introduced the i23 series in detail, covering chip design, module design, and reliability. Compared with the previous i20 series and other industry products, the i23 series achieves VCEsat as low as 1.85V under 175°C operation, with Eon and Eoff at 152mJ and 135mJ respectively, significantly reducing overall losses. The diode, optimized through proton implantation technology, achieves a much lower forward voltage without increasing switching losses, while improving softness—making it more suitable for high stray inductance environments.

In addition, Dr. Paula Reigosa Diaz, R&D expert at Sun.King Semiconductor, gave a presentation titled “Impact of P-well Contact on Dynamic Losses in Scaled 1.2 kV SiC MOSFETs for Parallel Switching Applications,” sharing the company’s latest technological breakthroughs in silicon carbide devices.

Sun.King Technology also showcased its advanced supporting power component solutions. The laminated busbar features a low-inductance design to enhance power density and thermal performance. The integrated busbar combines electrical interconnection, sensing, and structural support into a compact, reliable solution for battery systems. Its power electronic capacitors have reached internationally advanced standards, capturing a 75% market share in China’s first ±800 kV ultra-high-voltage flexible DC transmission project (Gansu–Zhejiang).

Notably, Sun.King Technology demonstrated its unique expertise in the pulse power field. With 25 years of accumulated know-how, the company has become a key technology provider in areas such as controlled nuclear fusion, delivering customized solutions for more than 80 global projects, including several internationally renowned fusion research programs.

The booth attracted large crowds of industry experts and clients, who engaged in in-depth exchanges through product displays, technical presentations, and live demonstrations. Many expressed strong interest in Sun.King Technology’s solutions and signaled intentions for further collaboration.

Sun.King Technology reaffirmed its commitment to continuous innovation, aligning with the global energy transition to provide more efficient and reliable solutions for new energy and industrial control applications. The company will continue to expand R&D investment, deepen international cooperation, and drive advances in power semiconductor technology and application innovation—contributing to the sustainable development of global green energy.

Through this major industry event, Sun.King Technology not only demonstrated its technical capabilities but also underscored the determination and ability of domestic power semiconductor enterprises to drive innovation and industry growth. As global demand for clean energy continues to rise, Sun.King Technology is poised to play an increasingly important role in the power semiconductor sector.
