Data centers become "killer application" for new power transformer tech
摘要
数据中心成为美国电力需求激增的最大推手，同时也加速了对固态电力变压器技术的投资。传统变压器依赖1880年代的手工绕线设计，无法量产且交付周期长达数年，既阻碍电网扩容，也延缓老旧设备更换。AI数据中心建设热潮正推动这一现代电力电子技术成为缓解电网压力的潜在突破口。
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.
