UniSiC's 'Shunying' SiC Dual-Energy CT High-Voltage Generator Ushers in a New Era of Customized Medical Imaging Equipment
Medical imaging equipment, hailed as a cornerstone of national strength, features extremely high technical barriers. After more than 30 years of independent innovation, China has gradually broken the monopoly held by imported products. With the continuous rise in the localization rate,Made in ChinaImaging equipment has expanded beyond domestic borders to serve the global market.
After achieving full autonomy and controllability over the complete systems, the next challenge is to address the bottleneck issues concerning core subcomponents of imaging equipment. The Ministry of Industry and Information Technology of China has listed core components of imaging equipment as “bottleneck” technologies. In the 14th Five-Year Plan for the Development of the Medical Equipment Industry, it was proposed that by 2025, China would achieve significant breakthroughs in key components for high-end medical equipment, with product performance and quality reaching international standards.
The three core components of CT imaging equipment—the high-voltage generator, X-ray tube, and detector—serve as the backbone of the entire system. Only by achieving differentiation in these core components can the overall performance of the equipment be fully realized. How to enhance imaging equipment performance and market share through product differentiation remains a persistent challenge for original equipment manufacturers (OEMs) in the medical imaging industry.
Recently, UniSiC, a leader in core silicon carbide (SiC) power components, unveiled another masterpiece in its “Shunying” series. This 42 kW, 168 kV SiC dual-energy integrated CT high-voltage generator is pin-to-pin compatible with the high-voltage generators of current mainstream CT models in terms of form factor, yet its performance specificationsGreat Potential. The kV rise and fall times are less than 200 microseconds, approximately faster than the currently most popular American equivalent product in terms of market share.100×Furthermore, by leveraging self-developed ultra-low stray inductance silicon carbide (SiC) power semiconductor modules, insulation packaging with extremely low distributed capacitance, and 500 kHz ultra-high-frequency precision control, the system achieves high-speed switching between 80 kV and 140 kV with a switching time of less than 150 microseconds, thereby enabling dual-energy imaging in CT systems. This breakthrough not only ends the complete reliance on U.S. imports for CT high-voltage generators and truly fills a domestic gap, but also delivers internationally leading product performance metrics, facilitatingMade in ChinaDomestic Brand CT Ushers in a New Era of Spectral Imaging.
Shunying 42kW 168kV Silicon Carbide Dual-Energy Integrated CT High-Voltage Generator
Currently, this silicon carbide dual-energy integrated CT high-voltage generator has completed system integration and commissioning as well as dual-energy testing and validation, and is about to enter the mass production phase.
Dr. Mao Saijun, Founder and CEO of Chenxin Technology, stated that the company has established in-depth collaborations with multiple leading manufacturers of complete imaging equipment systems—including Fortune Global 500 companies and China’s top-tier domestic manufacturers. Chenxin Technology’s full range of Shunying products will continue to empower these OEMs to achieve performance breakthroughs.
The core R&D team of the Instant Imaging product line was recruited en bloc from GE. In 1896, one year after Wilhelm Röntgen’s discovery of X-rays, GE scientist Elihu Thomson designed an X-ray imaging device for diagnosing fractures and locating foreign bodies within the human body. Since then, GE has maintained a long-standing leadership position in the field of medical imaging, achieving full independent control over the entire industrial chain for core power components. Leveraging an innovation-driven R&D philosophy, the core R&D team of Instant Imaging has led the development of multiple generations of core CT and X-ray high-voltage generator products, which have been deployed in some of the world’s most advanced CT systems, including the GE Revolution CT.

According to the Shunying R&D team, 32kW and 50kW models will be released successively.Silicon Carbide Dual-EnergyNew product portfolios, such as CT high-voltage generators, empower imaging equipment manufacturers to stay ahead of the curve and stand out from the competition by leveraging high-frequency, intelligent, and customized core subcomponents—all at an affordable price point.
Furthermore, through independent innovation and forward-looking R&D, the team has successfully overcome the next-generationUltra-Fast kV Switching Control for Silicon Carbide Dual-Energy CT High-Voltage Generators(transient switching between 80 kV and 140 kV within tens of microseconds), along with other key technologies such as independent transient control of kV and mA in dual-energy CT high-voltage generators. Leveraging independently controlled, internationally leading core technologies, we are empowering medical imaging equipment to usher in a new era of customization.
