Distributed point-of-use power supply architectures

This paper presents distributed point-of-use power supply (DPUPS) architectures for applications in advanced telecommunication and computer systems. The conventional architectures are reviewed. Based on the review DPUPSs are derived with the features including single-stage power conversion for multiple outputs regulation, high-voltage-low-current on-board power distribution, and power conversion into the required low-voltage at the point of load. DPUPS major advantages include fewer power components, reduced power losses, save of the PCB area, and improved voltage regulation at point-of-use. DPUPS implementations are given, and experimental results are presented as proof of concept.
