Infineon Unveils Next-Gen Battery Backup Solutions to Power AI Data Centers with Unmatched Efficiency and Reliability

Adam White, President of Infineon’s Power & Sensor Systems Division, stated, “Ensuring uninterrupted power for AI systems is critical to maintaining process continuity and seamless operations. Our energy-efficient battery backup units are designed to keep AI servers running smoothly with outstanding performance, flexibility, and efficiency across various power levels. By leveraging all three key semiconductor materials—silicon (Si), silicon carbide (SiC), and gallium nitride (GaN)—Infineon is setting a new standard for powering AI data centers.”

The cost of downtime or system failures in AI data centers can be exceptionally high. According to a 2024 ITIC survey, 41% of respondents reported that an hour of downtime costs between $1 million and $5 million or more, with 35% of failures attributed to power component quality issues. To address this challenge, Infineon’s Partial Power Converter (PPC) technology has emerged as a leading solution for battery backup systems, offering a semiconductor-based approa

A mid-range solution, the 5.5 kW BBU, incorporates Infineon’s proprietary topology, combining Si and GaN technologies to achieve ultra-high efficiency and power density. Meanwhile, the industry-first 12 kW system integrates multiple 4 kW power conversion cards, leveraging Infineon’s PSOC™ microcontrollers, 40 V and 80 V OptiMOS™, and EiceDRIVER™ gate drivers to deliver unmatched performance and flexibility. This system achieves four times the industry’s average power density. By paralleling multiple cards on the motherboard, higher power levels can be achieved, enabling scalability and simplified maintenance. If one card fails, the system continues operating at a reduced capacity, minimizing downtime and ensuring high reliability. This modular approach allows customers to tailor the system to specific power requirements without redesigning the entire infrastructure, providing significant advantages in both performance and reliability.

To further demonstrate the capabilities of its latest BBU technology, Infineon is developing full-system demonstrators for its battery backup solutions. These demonstrators will showcase the advantages of PPC technology in real-world applications, providing a clear roadmap for the next gener
