Accelerate your SST design with with Infineon's market leading solutions and unlock the future of advanced power distribution

As global demand for electricity continues to rise—fueled by data centers, the electrification of transportation, increased industrial activity, and higher cooling requirements—conventional power grids are coming under growing pressure. Solid-state transformers (SSTs) provide a transformative solution by fundamentally changing how public grids interface with end devices. By utilizing advanced semiconductor technologies, SSTs enable a universal power electronic architecture that replaces traditional systems based on low-frequency transformers. As a leader in power electronics, Infineon supports the development of highly energy-efficient SST solutions. Its comprehensive, ready-to-deploy portfolio spans all key areas, including power conversion, microcontrollers, security, auxiliary power supplies, sensing and communication

Diagram illustrates a single-phase subsystem converting medium-voltage AC to low-voltage DC. The left side shows MV AC 10–34.5 kV input feeding AC/DC and DC/AC stages with an MFT transformer, and the right side outputs LV DC ≥ 400 V. Below, functional blocks include gate driver, sensing, auxiliary power supply, microcontroller, memory, connectivity, and security. Arrows indicate signal and power flow between the conversion stages and control electronics.
