Infineon Technologies AG and LS ELECTRIC have signed a Memorandum of Understanding (MoU) to collaborate on high-efficiency direct current (DC) power infrastructure solutions for AI data centers and next-generation power grids. Rapid advancements in AI, the resulting increase in data center power demand and the expansion of digital infrastructure are driving the need for efficient power distribution technologies. The collaboration will focus on key DC infrastructure areas, including power conversion systems for energy storage systems, solid-state transformers (SSTs) and solid-state circuit breakers (SSCBs). SSTs can be up to 30 percent smaller and lighter while offering higher efficiency compared to conventional transformers. SSCBs use semiconductors and smart algorithms to interrupt current flow on the microsecond scale. Under the MoU, Infineon will support the development of high-efficiency, high-performance DC power infrastructure systems.
