AI data centers need more than power. They need power quality.
According to the IEA base case, global data-center electricity consumption is projected to reach around 945 TWh by 2030, growing at approximately 15% per year from 2024 to 2030. Electricity use from accelerated servers, largely driven by AI adoption, is projected to grow by around 30% annually.
As AI infrastructure scales, the challenge is not only how to supply more power. It is also how to manage:
• higher rack power density;
• fast GPU workload fluctuations;
• DC-bus stability in architectures such as 800 VDC;
• ripple current, transient stress, thermal stress and long-term reliability.
NVIDIA’s discussion of the 800 VDC AI Factory architecture highlights the need for multi-timescale energy buffering. High-power capacitors located close to compute racks can respond to millisecond-to-second power spikes and short valleys, while battery energy-storage systems handle longer-duration power shifts.
This is where film capacitors become part of the power-quality infrastructure:
DC-link ripple filtering to support a cleaner and more stable DC bus.
Transient power buffering for fast changes in power demand.
Low ESR / low ESL to help reduce high-frequency losses and parasitic effects.
High-frequency reliability for demanding switching and continuous-operation environments.
Film capacitors are not a substitute for grid-scale or long-duration energy storage. Their value lies in enabling reliable, efficient and responsive power conversion at the point where energy is converted and delivered to the AI rack.
For AI data centers, EV chargers, solar inverters and other high-power conversion systems, capacitor selection must be matched to the topology, DC-bus voltage, ripple current, thermal design, insulation system and lifetime target.
The future of AI factories will depend not only on how much power they consume, but also on how intelligently that power is conditioned and delivered.
