20100265628 | Redundant Power Supply with a Switchable, Linear Voltage Regulator - A system is provided that effectively obviates shortcomings of conventional, diode-ORed, redundant power supply systems by forcing a primary power source to provide power to the system load most the time, even when the primary source provides a lower voltage than that of a secondary power source. This preferential selection of the lower-voltage primary is achieved by interposing a power switching unit between the secondary power source and the ORing diode in front of the load. The power switching unit of the illustrative embodiment comprises a voltage regulator that is regulated at a first voltage level, which is lower than the nominal output voltage level provided by the primary power source. Meanwhile, the primary power source is able to charge the secondary power source, which is a battery in the illustrative embodiment, so that the secondary power source can provide power to the load when the primary power source is either interrupted or falls below the first voltage level. | 10-21-2010 |
