As AI workloads continue to drive up data center power demands, both AC and 400V DC rack power distribution present compelling solutions for improving efficiency and scalability. While AC infrastructure remains dominant, its inefficiencies are becoming more apparent, particularly in high-power-density AI data centers.
Data centers are increasingly adopting 400V DC rack power distribution as an alternative to traditional AC systems, driven by the need for improved efficiency, reliability and cost-effectiveness.
AC power remains the dominant method of power distribution in data centers due to existing infrastructure and standardization. (Figure 1) However, as AI workloads drive unprecedented energy consumption, the inefficiencies of AC power systems become increasingly evident.
Eltek's Converged Power Solution caters for all power needs in the data center. It combines the advantages of modern, modular power technology while meeting all AC and DC load requirements. The Converged Power Solution (CPS) is modular. In the unlikely event of a module failing, it can be replaced in minutes without afecting any loads.
To address this, data centers are exploring the integration of both high-efficiency AC and 400V DC rack power distribution by leveraging mSiC™ technology to optimize power conversion,
