More compact and higher reliability power source system
First Claim
1. A higher reliability power source system for computing loads, the system comprising:
- a high voltage DC bus connected to a number of high voltage 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 housed in a cabinet including a plurality of power supply modules, each power supply module including;
a number of DC/DC converters connected in parallel between the high voltage DC bus and the low voltage DC bus, anda 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 utilizing pseudo-impedance to provide load sharing with other power supply modules without direct communication with other power supply modules and without feedback from a point of common reference.
