On October 20, the latest list of national-level "Little Giant" enterprises — specialized, sophisticated, distinctive, and innovative companies — was officially announced. Three subsidiaries of Sun.King Technology Group Co., Ltd. (hereinafter referred to as "Sun.King Technology Group") have been newly recognized:

• Sun.King Pacific Semiconductors Technology (Zhejiang) Co., Ltd. ("SwissSem China"),
• Jiashan Huarui Sun.King Electrical Equipment Technology Co., Ltd. ("Jiashan Huarui Sun.King"), and
• Wuxi Sun.King Power Capacitor Co., Ltd. ("Wuxi Sun.King").

Together with Wuhan LandPower Co., Ltd., which had already been granted the same title, Sun.King Technology Group now boasts four "Little Giant" enterprises under its umbrella. This recognition not only affirms the technological excellence and professional strength of each company but also highlights the Group's long-term strategy of focusing on technological innovation and niche market leadership.

Four "Giants" Leading Distinct Market Segments

To further reinforce its core competitiveness in the power electronics industry, Sun.King Technology Group has strategically cultivated specialized subsidiaries that dominate key market segments. The newly recognized three "Little Giants", together with Wuhan LandPower Electric, form a robust and complementary innovation network that collectively leads in multiple areas.

• Jiashan Huarui Sun.King specializes in ultra-high-voltage (UHV) DC anode saturation reactors. By leveraging proprietary technologies, it has successfully broken foreign monopolies      and become the only domestic supplier with full independent intellectual property rights in this field.
• Wuxi Sun.King focuses on the research and production of power capacitors, whose reliable and stable performance has made them widely used in major national UHV projects, providing a solid foundation for a safer and more efficient power system.
• SwissSem China is dedicated to advancing power semiconductor technology. Its newly developed 7th-generation IGBT chips and world-class SiC chips are accelerating the localization and upgrade of high-end power semiconductor devices in China.
• Wuhan LandPower excels in grid intelligence, particularly through its independently developed online monitoring system for DC support capacitors used in flexible DC transmission systems — a key innovation that enhances the safety and reliability of new power infrastructure.

Together, these four companies constitute Sun.King Technology Group's core competitiveness matrix in the power electronics industry, each contributing unique strengths while supporting one another's technological and market advancement.

Innovation-Driven Growth Empowered by R&D

The success of these four "Little Giant" enterprises is no coincidence — it is the result of Sun.King Technology Group's long-standing commitment to innovation-driven development.
Since its founding in 2002, the Group has made technological innovation its core strategy. It has established R&D centers across Jiashan, Wuxi, Wuhan, and Ningbo, as well as several R&D teams in Europe. To date, the Group holds over 260 patents and has received five national-level energy technology achievement certifications.

Sun.King Technology Group's industrial influence extends deeply into multiple strategic sectors. The Group has participated in over 40 domestic high-voltage DC transmission projects, playing a vital role in China's UHV power grid development. Its technologies are also widely applied across the wind power, photovoltaic, energy storage, and electrified transportation sectors (including rail transit and new energy vehicles), as well as industrial energy efficiency initiatives — all contributing to the realization of China's carbon neutrality goals. Moreover, Sun.King's innovations support frontier research such as high-energy physics and controlled nuclear fusion, advancing both scientific and energy transformation.

By establishing a network of specialized and innovative "Little Giant" enterprises across the power electronics value chain, Sun.King Technology Group has built a powerful ecosystem of industrial excellence. Looking ahead, as the Group continues to deepen technological innovation, its mission of  "Empowering Green Energy Development through Technological Innovation" will gain even stronger momentum and practical realization.
