Facility level power conversion: SST

In this episode of Podcast4Engineers, host Peter Balint speaks with Valerio Zerillo about the growing role of Solid-State Transformers (SSTs) in powering AI-driven data centers. The discussion explores how traditional low-frequency transformers are reaching their limits due to increasing power demands, space constraints, and scalability challenges. Valerio explains how SSTs leverage advanced power semiconductors, silicon carbide, gallium nitride technologies, and intelligent control systems to deliver higher efficiency, flexibility, and reduced footprint. The episode also looks ahead to the future of power infrastructure, including medium-voltage DC grids and the integration of renewable energy sources to support next-generation AI and high-power applications.
