LS ELECTRIC America presents direct current (DC) power systems to reduce energy losses and support rising AI workloads at Data Center World 2026.
LS ELECTRIC America will highlight its DC grid power system concept for AI data centers at Data Center World 2026, focusing on improving energy efficiency and supporting the rapid growth of high-density AI server infrastructure.
Challenge: Rising power demand in AI data centers
The increasing use of high-performance AI chips—such as those from NVIDIA—is driving significant growth in server rack power density and thermal loads.
LS ELECTRIC will present projections showing how:
GPU power consumption is increasing
Rack-level power demand is rising through 2028
Cooling and infrastructure requirements are becoming more complex
Solution: DC power systems for improved efficiency
At the core of LS ELECTRIC’s approach is the use of DC (direct current) power distribution across the data center.
Compared with traditional AC systems, DC architectures can:
Reduce total power system losses from ~25% to ~10%
Minimise energy conversion stages
Improve overall electricity utilisation from source to server rack
The system integrates technologies such as:
Solid State Transformers (SST)
DC/DC converters
Solid State Circuit Breakers (SSCB)
System architecture: From grid to rack
The company will demonstrate how DC systems can be applied across the entire energy chain, including:
Power generation and grid interface
Medium- and low-voltage switchgear
UPS and energy storage systems
Data hall distribution and rack-level delivery
This end-to-end approach supports more efficient and scalable AI data center designs.
Cooling strategies: Managing higher heat loads
To address increasing thermal demands, LS ELECTRIC will also present various cooling technologies, including:
Air-based systems (CRAH, CRAC, cooling towers)
Liquid cooling solutions (cold plates, immersion cooling, CDU systems)
These solutions are critical for maintaining performance and reliability in high-density AI environments.
Industry relevance: Preparing for next-generation AI infrastructure
As AI workloads continue to expand, data center operators must rethink both power distribution and cooling strategies. DC grid solutions offer a pathway to:
Higher efficiency
Reduced operational costs
Improved scalability for future AI applications
