AI Technical Summary

Technical Problem

The current architecture of data centers is not adapted to the increase in computing power of equipment due to high manufacturing costs and size, primarily because transformers and electrical connections are sized for significant electrical power consumption, which is inefficient and costly.

Method used

A method for controlling an electrical distribution system where conversion modules are connected in series with a power supply, converting medium voltage to low voltage, and a control method regulates DC voltage and apparent power to maintain balance, eliminating the need for intermediate low-voltage distribution networks.

Benefits of technology

This approach reduces material costs, particularly copper usage, and improves compactness by simplifying the electrical infrastructure while ensuring stable power delivery to electrical loads.

Abstract

The present invention relates to a method for controlling an electrical distribution system comprising a power supply delivering a medium-voltage alternating current, electrical loads, and a load-conversion module. The input terminals of all modules are connected in series with each other and with the power supply. Each module includes a converter delivering a low-voltage direct current to its electrical load from the medium voltage. The method comprises, for each module, adjusting the active power delivered by the module according to the active operating power of its electrical load and maintaining a constant apparent power of the module by regulating the amplitude and phase shift of the voltage across its terminals, based on the active power delivered by the module to its electrical load, the voltage and current delivered by the power supply to the modules, and the number of modules.Figure for the abridged version: 1.
