Hopewind Selects Wolfspeed to Power the Future of Wind Energy with Advanced Silicon Carbide Technology

Collaboration enables Hopewind to launch the wind power industry’s first all-silicon carbide power cabinet

Wolfspeed, Inc. (NYSE: WOLF), a global leader in innovative silicon carbide power solutions, today announced a collaborationwith Hopewind, a global innovator in renewable energy solutions. Together, the two companies will advance the development of the next generation of wind power solutions by integrating Wolfspeed’s cutting-edge 2.3kV LM Pack Module into Hopewind’s advanced highly modular and lightweight 950Vac Wind Power Converter.

Hopewind, one of the largest wind power converter suppliers in China, has taken a novel approach to their wind power solution: This product utilizes silicon carbide devices and high-reliability packaging technology to achieve a up to 38% increase in power density and a high switching frequency of up to 6kHz, significantly increasing efficiency and reliability. The collaborationbetween Wolfspeed and Hopewind is expected to accelerate the development of next-generation wind power solutions for markets worldwide.

Wolfspeed’s silicon carbide solutions are helping drive the transition to next-generation energy systems that are more sustainable and cost-effective. The company’s 2.3kV LM Pack Module offers substantial system benefits, including simplified system design, higher efficiency, increased power density, and improved reliability—key factors that reduce overall system cost and provide superior performance for large-scale wind power applications. The 2.3kV LM Pack Module is expected to be commercially available in early 2026.

Wolfspeed's collaboration with Hopewind marks a critical milestone in the ongoing evolution of the wind power industry, helping to pave the way for cleaner, more efficient energy solutions on a global scale.

“We are excited to be working with Hopewind, a recognized leader in the renewables industry,” said John Perry, VP and General Manager, Medium and High Voltage Products at Wolfspeed. “Our 2.3kV LM Pack Module is perfectly aligned with the growing demand for higher voltage, higher current, and higher efficiency systems in the wind power sector. This collaboration not only strengthens Wolfspeed’s position as a trusted long-term SiC provider, but also helps meet the increasing global demand for renewable energy solutions.”

Hopewind, headquartered in Shenzhen City, China, was recently name to the list of photovoltaic inverter manufacturers that meet the Tier 1 standards for the globally renowned energy research institution Bloomberg New Energy Finance (BloombergNEF, abbreviated as BNEF). There are only seven companies worldwide that have successfully made it to the Tier 1 level, affirming Hopewind's global influence and competitiveness in the field of photovoltaics.

“Hopewind is thrilled to work with Wolfspeed to enhance the performance of our wind power converters with their world-class silicon carbide technology,” said Wang Yan, Vice President at Hopewind. “By incorporating Wolfspeed’s advanced 2.3kV LM Pack Module, we are taking a significant step forward in delivering high-efficiency, reliable, and cost-effective solutions for the wind power industry.”
