The Fraunhofer Institute for Solar Energy Systems ISE has developed and suc-cessfully commissioned the world’s first medium-voltage string inverter for large-scale power plants. By feeding power into the medium-voltage grid, the “MS-LeiKra” project team has demonstrated that PV inverters are technically capable of handling higher voltage levels.
The benefits for photovoltaics in-clude enormous cost and resource savings for passive components and cables. The device lays the foundation for a new system concept for the next genera-tion of large-scale PV power plants, which can also be applied to wind turbines, electric mobility and industrial applications.
Modern PV string inverters have an output voltage of between 400 VAC and 800 VAC. Although the output of power plants is steadily growing, voltage has not yet been increased. There are two reasons for this: First, building a highly efficient and compact inverter based on silicon semiconductors is a challenge. Second, there are currently no PV-specific standards that cover only the low-voltage range (max. 1,500 VDC / 1,000 VAC).
In a project funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK), Fraunhofer ISE, in collaboration with Siemens and Sumida, has developed an inverter that enables the output voltage to be increased to the medium-voltage range (1,500 V) at 250 kVA. The key to this is the use of silicon carbide semiconductors, which have a higher blocking voltage.
The research team has also implemented a more efficient cooling concept using heat pipes, which reduces the amount of aluminum required.
Thinner cables offer huge savings potential
An average photovoltaic power plant requires dozens of kilometers of copper cables. Increasing the voltage generates significant savings potential: At today’s possible output voltage of 800 VAC, a 250 kVA string inverter requires cables with a minimum cross section of 120 mm². By increasing the voltage to 1,500 VAC, the cable cross section can be reduced to 35 mm².
This in turn cuts copper consumption by around 700 kilograms per kilometer of cable. “Our resource analyses show that in the medium term, the electrification of the energy system will lead to copper becoming scarce. Increasing the voltage allows us to save valuable resources,” says Prof. Dr. Andreas Bett, Director of the Fraunhofer Institute for Solar Energy Systems ISE.
Standards need to change
With the “MS LeiKra” project, we are leaving the scope of low-voltage (<1000 VAC / <1500 VDC) standards. There are currently no PV-specific standards for this range. This is why the project team is also working on the standards that would result from increasing the voltage.
Finding a demo project partner
Having fed power into the medium-voltage grid successfully, the research team is now looking for solar farm developers and grid operators to test the power plant concept in the field.
Besides photovoltaics, moving beyond low voltage is also of interest for other applications, such as wind turbines, where the growing system capacities also require cables with large cross sections. The same is true for the charging infrastructure for large electric vehicles and vehicle fleets, and for industrial grids, where medium-voltage inverters could save a lot of material if cable cross sections could be reduced.

onsemi announced the completed expansion of its state-of-the-art, world-largest silicon carbide (SiC) fabrication facility in Bucheon, South Korea. At full capacity, this fab will be able to manufacture more than one million 200 mm SiC wafers per year.
To support the ramp in SiC manufacturing capacity, onsemi plans to hire up to 1,000 local employees over the next three years to fill the mostly highly technical positions – a more than 40% increase over the present workforce of about 2,300.
Silicon carbide devices are a critical component for power conversion in electric vehicles (EVs), energy infrastructure and high-power EV chargers. The rapidly growing demand for these products has created a surge in demand for SiC chips, with demand outpacing supply for the foreseeable future. The expansion of the Bucheon fab addresses the pressing need for additional production capacity, allowing onsemi to continue to provide supply assurance for its customers and strengthen its leadership in intelligent power solutions.
Construction of the new advanced 150 mm/200 mm SiC fab line along with the high-tech utility building and adjacent parking garage began in the middle of 2022 and was completed in September 2023. The expansion of the 150 mm/200 mm SiC Epi and wafer fab emphasizes onsemi’s focus on building out its vertically integrated silicon carbide manufacturing supply chain at brownfield locations. The Bucheon SiC line is starting with the production of 150 mm wafers and will be converted to 200 mm in 2025 upon qualification of the 200 mm SiC process.
onsemi’s leadership was joined by a delegation of dignitaries led by Vice Governor for Economy of the Gyeonggi-Do Taeyoung Yeom; followed by Bucheon City Mayor YongEek Cho; National Assembly delegates; and Bucheon Chamber of Commerce and Industry Chairman JongHuem Kim. Also in attendance were representatives from local communities, customers, suppliers and the semiconductor industry.
onsemi CEO Hassane El-Khoury opened the event, noting, “The 150 mm/200 mm SiC wafer fab in Bucheon is critical to the continued success of our fully integrated SiC supply chain, enabling us to support the acceleration of electrification globally. The last five years have shown what extraordinary performance our Bucheon team is capable of, and what we can achieve when we work together with governmental agencies toward the common goal of a more sustainable future.”
“I am truly impressed by onsemi’s diligent and yet fast execution of its strategic plan to expand the Bucheon SiC wafer fab,” said Bucheon City Mayor YongEek Cho. “Not only will the city of Bucheon benefit from the creation of new employment opportunities in technology, but it will also be a part of laying the foundation for a sustainable ecosystem through electrification.”
