Abstract
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.
