This invention features a more compact and higher reliability power source system for computing loads, the system including a high voltage DC bus connected to a number of DC sources each connected to the high voltage DC bus by a switch configured to deliver to the high voltage DC bus the DC source with the highest DC voltage, a low voltage DC bus connected to the computing loads, and a power supply including a number of DC/DC converters connected in parallel between the high voltage DC bus and the low voltage DC bus, and a controller configured to modulate each DC/DC converter to convert the high voltage on the high voltage DC bus to a low voltage output on the low voltage DC bus.

L'invention concerne un système source d'énergie plus compact et de meilleure fiabilité conçu pour des charges de calcul, qui comporte un bus CC haute tension relié à plusieurs sources CC qui sont, chacune, reliée, à ce bus par un commutateur destiné à fournir au bus CC haute tension la source CC avec la tension CC la plus élevée, un bus CC basse tension relié aux charges de calcul, et une alimentation électrique comprenant plusieurs convertisseurs CC/CC reliés en parallèle entre le bus CC haute tension et le bus CC basse tension, et un régulateur destiné à moduler chaque convertisseur de façon à transformer la haute tension sur le bus CC haute tension en sortie basse tension sur le bus CC basse tension.
