Briefings

Researchers at North Carolina State University are developing solid-state transformers to replace traditional transformers in power grids. These devices use semiconductors to control electricity flow, allowing for smaller, more efficient units that can handle high-voltage transmission. A recent test by the New York Power Authority and EPRI showed a prototype transformer was 98% efficient, compared to 96% for conventional alternatives, though it cannot yet replace all traditional transformers.

Key points

• Solid-state transformers use semiconductors like silicon carbide to control current frequency, enabling smaller magnetic cores compared to traditional transformers.
• A prototype transformer tested by the New York Power Authority and EPRI achieved 98% efficiency, significantly higher than the 96% efficiency of conventional transformers and rectifiers combined.

Context

Transformers are essential for stepping voltage up and down to transmit electricity efficiently, but they are bulky, expensive, and in short supply. Solid-state versions offer compact designs and better control over power flow, potentially reducing energy loss and improving grid reliability for EVs and data centers.

Limitations

The evidence covers only one-megawatt transformer testing conducted in August at an EPRI test site. The prototype was built in Lukic's lab and represents the first capacity test for this technology, with no data on widespread deployment or long-term reliability.
