Infineon Technologies said on 29 September 2026 that it will supply silicon-carbide (SiC) power devices to Eaton for use in the MVSST 2.0 medium-voltage solid-state transformer platform. The collaboration concerns a platform designed for deployment in Asia-Pacific and the power conversion needed to connect AI data centres to the electricity grid. The stated architecture targets 800-volt direct-current (VDC) distribution. That figure describes a design context; it does not report the operating voltage of a particular data centre or installed field capacity.

Eaton says MVSST 2.0 is designed for high-density computing infrastructure and 800 VDC power distribution. The company says reducing conversion stages compared with conventional architectures can improve efficiency, power density and deployment flexibility. A simpler conversion chain may reduce losses and equipment footprint, but the release does not quantify a percentage efficiency gain, megawatt capacity or the volume of devices delivered to a data-centre project. The platform is intended to bridge medium-voltage grid input and direct-current distribution to computing equipment.

Infineon’s SiC devices will be used in power conversion. Silicon carbide is a wide-bandgap material used for semiconductor switches that can operate under high electric fields. The announcement says the platform is among the first medium-voltage solid-state transformer platforms to achieve IEC certification, but does not tie that certification to a specific power rating or measured on-site savings. The companies are also exploring future platforms based on 2.3-kilovolt and 3.3-kilovolt SiC power modules. Those voltages describe a development direction and are not the same measure as the current MVSST 2.0 distribution target.

The commercial relevance lies at the intersection of rising electricity demand from data centres and the need for more efficient, scalable grid equipment. AI accelerators draw power at high density, while reliable operation and compatibility with renewable energy are also design priorities. The announcement reports a supply collaboration and technical objectives, not third-party field performance, contract value, shipment dates or annual device volume. The efficiency benefits described by the companies should therefore be understood as platform design goals rather than independently measured results. Deployment and performance depend on project configuration and operating conditions.

A second limit concerns timing and deployment: beyond the platform’s APAC deployment design, the release names no site or commissioning date. The 800 VDC target is a nominal distribution level describing the system architecture; it should not be interpreted as a constant measured value under every operating condition. Project outcomes will depend on grid connection, load profile and installation configuration.
