First and second power supplies are connected in parallel to power a load. Each power supply includes a primary stage and a regulator stage. Each primary stage regulates voltage on an internal bus that is input for each regulator stage. Each regulator stage regulates a regulated bus connected to the load. A power meter detects power provided to the load and determines if the provided power is below a predefined power threshold. A regulator control module shuts down the regulator stage of the first power supply after the provided power falls below the predefined power threshold so the second power supply powers the load and the primary stage of the first power supply remains operational. A recovery module starts up the regulator stage of the first power supply after failure of the second power supply. | 07-02-2009 |
| 20100164427 | APPARATUS, SYSTEM, AND METHOD FOR FAULT TOLERANT COOLING IN A REDUNDANT POWER SYSTEM - An apparatus, system, and method are disclosed for fault tolerant cooling in a redundant power system. The apparatus receives power from a common power bus to power one or more power supply fans. The apparatus detects a non-functioning redundant power supply.

In addition, the apparatus uses the received fan control signal to synchronize a fan speed of a power supply fan within the non-functioning redundant power supply. The fan speed is synchronized with at least one fan control signal of a power supply fan within a functioning redundant power supply. Thus, the power supply fans of a non-functioning power supply continue to operate and are synchronized with power supply fans in functioning power supplies. | 07-01-2010 |

The second power supply includes switching elements that have lower switching losses than switching elements of the first power supply. A sensing module measures power. A switching module starts up the second power supply and shuts down the first power supply if the measured power falls below the minimum power threshold, and starts up the first power supply and shuts down the second power supply if the measured power rises above the minimum power threshold. | 07-02-2009 |
| 20100008005 | APPARATUS, SYSTEM, AND METHOD FOR LOSSLESS REVERSE VOLTAGE PROTECTION - An apparatus, system, and method are disclosed for preventing reverse current in a switching power supply. An electrical connector receives an input current from an electric source. An input current limiting module substantially prevents the input current from reaching a switching power supply when the input current is flowing in a reverse direction. A voltage reduction module reduces an input voltage of the switching power supply to a switching voltage when the input current is flowing in a forward direction. A switching module closes a switch in response to the voltage reduction module providing the switching voltage. The switch provides the input current a lower impedance path to the switching power supply than does the input current limiting module. | 01-14-2010 |

A monitor module turns on the power supply for a monitor interval when the idle interval ends. During the monitor interval, the connection module determines whether the load has been connected to the output terminal of the power supply. An activation module turns on the power supply if the connection module determines, during the monitor interval, that the load has been connected to the power supply. If the load has not been connected, another idle interval is initiated. | 01-14-2010 |
