Abstract:
This paper discusses possible dc voltage options for information technology and telecom power architectures. Instead of considering an adaptation of existing architectures, it contemplates design factors without engineering preconditions. This is a technology planning approach based on systems fundamentals. Both conventional architectures and microgrid-based designs are discussed. The study reveals that there exist many tradeoffs which yield no particular best option. A compromise solution with a ± 150 V split phase microgrid-based architecture and a corresponding multiple-input SEPIC converter are also introduced in this paper.
