Recently, Xi’an WG Energy Technology Co., Ltd. (hereinafter referred to as "WG Energy") and Infineon Technology (hereinafter referred to as "Infineon") have officially reached an in-depth cooperation, joining hands to open a new chapter in energy technology innovation. Both parties will leverage Infineon's leading 1200 V TRENCHSTOP™ IGBT7 and CoolSiC™ MOSFET G2 SiC discrete device technologies to empower WG Energy to develop more compact and efficient universal SST, significantly improving their application performance in energy storage systems and charging piles. The two parties also plan to jointly introduce Infineon's new SiC modules into data center SST applications, strategically positioning themselves for the opportunities ahead of the explosive growth of SSTs in data centers, and working together to promote the continuous advancement and widespread adoption of energy technology.
In power systems, reliability serves as the cornerstone for the stable operation of SSTs and the assurance of power supply continuity, and it directly impacts operation and maintenance costs as well as overall economic benefits. Infineon's new-generation 1200 V CoolSiC™ MOSFET G2, with its innovative design, becomes an ideal choice for high-reliability SST applications: The enhanced .XT diffusion soldering technology significantly improves heat dissipation efficiency, enabling SSTs to operate stably under high-temperature conditions, markedly extending system lifetime and enhancing reliability; meanwhile, the trench gate design combined with stringent production control ensures a tighter distribution of gate threshold voltage parameters, guaranteeing high reliability when multiple devices are connected in parallel, while also simplifying system design and control. This provides the SST market with a high-reliability, easy-to-maintain premium solution.
CoolSiC™ MOSFET 1200V G2
WG Energy adopts 1200 V TRENCHSTOP™ IGBT7 and CoolSiC™ MOSFET G2 silicon carbide discrete devices in its SST system, and innovatively applies hybrid three-level topology technology, achieving a peak efficiency exceeding 98.5%, significantly reducing energy losses and improving energy utilization efficiency. At the same time, the system size is substantially reduced, the link structure is simplified, and system reliability is significantly enhanced at the overall link level, setting a dual benchmark for industry efficiency and reliability.

Mr. Gu Yixiang, Senior Vice President of Infineon and Head of the Industrial & Infrastructure Business for Greater China, stated: “As the energy transition accelerates and the SST market shows broad prospects, reliability becomes especially critical. With over two decades of deep involvement in SiC, Infineon leverages its profound understanding of the material and innovative process technologies to establish a reliability testing system that far exceeds industry standards. Coupled with rigorous production controls, we are committed to becoming the more reliable supplier of SiC solutions in the industry. Facing the explosive growth of the SST market, we have already positioned ourselves in advance, delivering high-reliability, high-efficiency power semiconductor solutions to inject strong impetus into the global energy transition and join hands with our partners to create a green future!”
Dr. Hao Xiang, founder and general manager of WG Energy, stated:
"With the vision of becoming a leader in power routers for the energy internet, WG Energy focuses on R&D and innovation in SSTs. By leveraging breakthrough technologies, we have rapidly captured the market—not only achieving over 100 SST units delivered, but also ranking first globally in shipments of SSTs for PV-storage-charging applications. As the global benchmark for SiC power devices, Infineon's new-generation CoolSiC™ MOSFET G2 products, with their high efficiency and high reliability, perfectly align with WG Energy's pursuit of excellence and provide solid support for SST technology breakthroughs. Looking ahead, both parties will continue to deepen their collaboration, expand SST application scenarios, and jointly build more efficient, safer, and more sustainable energy solutions."
