Data centers have become the largest driver of surging electricity demand that is straining US power grids. But the AI data center boom has also accelerated investment in a technology that could provide a silver lining for everyone—solid-state power transformers that replace industrial-age technology with modern power electronics.

Power grids currently rely on conventional transformer technology that is painstakingly assembled by hand and has a fundamental design dating back to the 1880s. Two copper wire coils manually wound around a steel core create electromagnetic fields that help step up voltage levels of alternating current electricity for long-distance transmission or step down voltage levels for the electricity use of homes and businesses. The largest power transformers cannot be mass-manufactured but are instead custom-built for each utility company’s electrical substations.

Manufacturing constraints, coupled with the scramble to upgrade US power infrastructure, have meant utility companies and other customers must wait up to several years for delivery of new power transformers. That is not only a problem for expanding power grid infrastructure to support growing electricity demand, but also delays the process of replacing aging power transformers.

Taiwan has indicted nine people—reportedly including an Nvidia senior manager and two Supermicro employees based in the country—who allegedly helped forge documents to cover up illegal exports of high-end AI servers to China in violation of US export controls.

On Monday, Reuters reported that prosecutors in Keelung did not release any names but confirmed that the suspects were “charged with breach of trust and document forgery.” One suspect linked to a related case remains at large, accused of the “siphoning of funds from a distributor company involved” in helping China get access to restricted Nvidia chips.

Since 2022, the US has required a license to export semiconductors to China, with the intent of protecting national security by staying ahead of China in the AI race. But after the US arrested Supermicro co-founder Wally Liaw in March for allegedly funneling $2.5 billion in restricted AI servers to China since 2024, Taiwan launched a separate probe to learn more about the scheme.
