摘要： An apparatus and system are disclosed for protecting a power distribution unit from an electrical fault. A fuse interrupts a flow of electrical current in response to the electrical current rising above a current rating of the fuse. A current sensor measures the amplitude of the electrical current and outputs a current amplitude signal. A relay interrupts the flow of electrical current in response to an OFF signal. A fault module receives the current amplitude signal and sends the OFF signal to the relay in response to the amplitude of the electrical current exceeding a threshold value. The relay, the fuse, and the threshold value are selected so that a switching time of the relay is less than an opening time of the fuse for an amplitude of the electrical current between the threshold value and a maximum fault current value, so that the relay prevents the fuse from opening.

摘要： An apparatus, system, and method are disclosed for a power supply that is efficient in both high and low power conditions. An integrated power supply regulates current on a regulated bus to maintain a regulated bus voltage under varying load conditions. The integrated power supply includes a first power supply rated to provide full load power to the load and second power supply rated to provide power at levels below a minimum power threshold. 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.

摘要： An apparatus for efficient power supply operation variable input line voltages. The apparatus includes a detection module that senses the input line voltage to the power supply and determines whether it is high or low voltage. A turn module sets the turns ratio of the transformer to a first turns ratio if the input line voltage is low voltage. The turn module sets the turns ratio to a second turns ratio if the input line voltage is high. In one embodiment of the invention, a high voltage is between 180 and 250 volts, while a low voltage is between 90 and 130 volts. A primary module sets the boost voltage of the power supply's boost stage to a first voltage if the input line voltage is low, while it sets the boost voltage to a second voltage if the input line voltage is high. The first voltage may, for example, be 200 volts, and the second voltage 400 volts.

摘要： An apparatus, system, and method are disclosed for a high efficiency redundant power system. 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.
