Low-Voltage dc System Building Blocks: Integrated Power Flow Control and Short Circuit Protection
Authors: Pavel Purgat, Aditya Shekhar, Zian Qin, Pavol Bauer
Sustainable power distribution for transportation, industry, and city infrastructure is a global-scale issue. Direct current (DC) power distribution increases system efficiency and reliability in systems with integrated storage, renewable energy, or variable-speed generators. This article gives an in-depth perspective on the advantages and challenges of DC power distribution systems, with a special focus on the current market status and trends. The paper discusses in detail three market segments with different adoption levels where DC is improving operational efficiencies and reducing capital investments. Finally, the article highlights the benefits of solid-state circuit breakers and partially rated power converters capable of creating future-proof, sustainable solutions and how these devices are essential for accelerating the adoption of DC systems.
