Higher voltage direct current (HVdc) power distribution configurations have the potential to reduce energy consumption and increase efficiency in the data center. However, if data center operators, equipment manufacturers, and others opt to make HVdc a primary power distribution configuration, some critical issues need to be resolved for maximum cost-effectiveness, ease of adoption, and safety related to HVdc. Although difficult, establishing global HVdc standards will help smooth adoption and avoid some of the expense and inefficiencies that the industry has had to deal with related to variances in AC power systems.
