摘要： An apparatus, system, and method are disclosed for safely connecting a device to a power source. The invention includes a power bus switch that operates to selectively allow operational power to flow from a power supply to a load. The operational power is independent of auxiliary power which may be separately provided to the load. A detection module determines whether an input impedance of the load is greater than a minimum impedance threshold in response to the load being connected to the power supply. A switch module causes the power bus switch to allow operational power to flow to the load in response to the detection module determining that the input impedance is greater than the minimum impedance threshold. Thus, if the load has an acceptable input impedance level, then operational power may be provided to the load without risk of failure to the power system.

摘要： According to one embodiment, a circuit for providing redundant power includes a first channel having a first input, a first electronic circuit breaker, and a first output, a second channel having a second input, a second electronic circuit breaker, and a second output, and a first transistor coupled to the first electronic circuit breaker, the first transistor in series with a second transistor coupled to the second channel. The circuit normally operates by providing power to the first and second outputs from the first and second channels, respectively. However, if the first channel fails, the transistors switch on to allow power from the second channel to feed the first output in the first channel in addition to feeding power to the second output, and vice versa. Other embodiments and methods for providing redundant power are described as well.

摘要： An apparatus, system, and method are disclosed for controlling fan speed in a power supply. The apparatus measures input power to the power supply and measures the output power provided by the power supply over an interval. The apparatus determines values for the input power and output power and, using the two, determines how much power has been dissipated in the power supply. Power dissipation values are associated with particular fan speeds, and the apparatus adjusts the speed of the fan in the power supply based on how much power was dissipated during the interval. Increasing levels of power dissipation increases the fan speed, and decreasing levels of power dissipation decrease the fan speed.

摘要： An apparatus, system, and method are disclosed for providing regulated electric power. At least two power buses transfer regulated direct current (“DC”) power from at least four power supplies to an electric load. The power supplies receive electric power from one or more electric sources and convert the electric power to the regulated DC electric power. A switch is connected between each of the power buses and the electric load. Each switch connects and disconnects a power bus to the electric load and transfers the regulated DC electric power from the buses to the electric load. An output power bus connection is disposed on each of the power supplies. Each of the power buses is connected to at least two power supplies and each output power bus connection connects the corresponding power supply upon which the output power bus connection is disposed to exactly one power bus.

摘要： An apparatus, system, and method are disclosed for determining power source failure. A sampling module samples an alternating current power waveform as input to a power supply, at a sampling frequency which is a multiple of a predetermined frequency, to obtain a sampled amplitude at a known point within the predetermined period. A comparison module compares the sampled amplitude to a stored threshold amplitude to obtain a comparison result, corresponding to the known point. An accumulation module accumulates most recent comparison results. A warning module asserts an early power off warning signal if a predetermined number of the most recent comparison results each indicate that the sampled amplitude is smaller in absolute value than the stored threshold amplitude.

摘要： An alternating current-to-direct current (AC-to-DC) power supply has a first stage providing a first DC voltage and a second stage providing a second DC voltage. The AC-to-DC power supply has a first efficiency at the first stage and a second efficiency at the second stage that is less than the first efficiency. The second DC voltage is also less than the first DC voltage. A blower is electrically connected to the first stage of the AC-to-DC power supply to receive the first DC voltage from the AC-to-DC power supply to power the blower. Electrical connection of the blower to the first stage of the AC-to-DC power supply instead of to the second stage of the AC-to-DC power supply wastes less power and is more efficient.

摘要： An apparatus, system, and method are disclosed for efficiently providing bias voltages. A first switching regulator stage that includes an inductor receives an input voltage and provides as an output an intermediate regulated output voltage. A second switching regulator stage receives as input the intermediate regulated output voltage and outputs a regulated main output voltage. The second switching regulator stage includes at least one switch controller that provides one or more signals to one or more switches in the second switching regulator stage to regulate the main output voltage of the second regulator stage. A secondary bias module utilizes a secondary winding coupled with the inductor of the first regulator stage to provide a secondary bias output voltage to the switch controller of the second switching regulator stage. The secondary bias output voltage is referenced to the main output voltage of the second switching regulator stage.
