In this episode of Podcast4Engineers, host Peter Balint speaks with Nancy Wang, Director of Application Marketing for UPS at Infineon, about why backup power is becoming a critical enabler of AI infrastructure. They explore how AI data centers are driving new approaches to uninterruptible power supplies (UPS), distributed battery backup, high-voltage DC architectures, and layered energy storage to meet increasingly dynamic power demands. The discussion also looks ahead to how future data centers will evolve from passive energy consumers into active participants in the power grid, making intelligent power management just as important as computing performance.

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.

In this episode of Podcast4Engineers' "We Power AI" series, host Kelsey Markl sits down with Dr. Diogo Varajao, Head of Power Supply and Battery Backup Systems Group at Infineon, to explore how power supply design is rapidly evolving to keep pace with the soaring energy demands of AI infrastructure. The conversation dives deep into the dramatic rise in GPU and server rack power consumption, from under 1 kilowatt per GPU just a few years ago to projections exceeding 600 kilowatts per rack in the near future, and what that means for data center architecture. Diogo walks through the generational shift in rack design, as well as novel energy buffer concepts, advanced PFC topologies, and the strategic use of WBG technologies to maximize efficiency and help hyperscalers drive down their Power Usage Effectiveness (PUE).

In this episode, host Kelsey Markl welcomes Head of Systems at Infineon’s Green Industrial Power Division Mehrdad Baghaie Yazdi back to the show, where they discuss the massive power demands of gigawatt-scale AI data centers and the necessary shift toward efficient DC grid architectures. They explore how solid-state transformers and advanced semiconductors are replacing traditional infrastructure to reduce energy losses and improve grid resilience.

AI is pushing our energy grid to its limits, but keeping up requires a sustainable approach, backed by the latest advancements in semiconductor technology. In this episode of our We Power AI series, Kelsey talks with Peter Wawer, Division President of the Green Industrial Power Division at Infineon, about what it really means to power AI sustainably, from the grid down to the server rack. They cover why battery energy storage, HVDC, and DC-powered data centers matter, and look ahead to what “physical AI” could mean for industry, robotics, and society.
