A system comprises a first equipment rack, a power distribution unit (PDU) and a plurality of rack connectors. The PDU is mounted in the first equipment rack and is configured to provide alternating current (AC) power that comprises a plurality of phases. The plurality of rack connectors mount within the first equipment rack, and each of the plurality of rack connectors couples to the PDU and provides access to the plurality of phases. Each rack connector is usable to accommodate a first device installed in the equipment rack that uses one or more of the plurality of phases, and is also usable to accommodate a second device installed in the equipment rack that uses one or more of the plurality of phases, thereby permitting each rack connector to couple to any of a plurality of devices, and permitting each of the plurality of devices to use any number of the plurality of phases. The number of phases used by the first device differs from the number of phases used by the second device.

An active protection circuit for a MOSFET isolated switched power supply system operates to control the switching of the MOSFET isolation switches. A monitoring circuit operates to sense and turn off the isolation switch of the currently active power supply if it senses reverse current flowing through the switch. Simultaneously, a controller receives indication that the active power supply is out of specification, and actively switches the system voltage source to the other power supply. The controller actively ensures that the isolation switch of the out-of-specification power supply remains off until it determines otherwise.

A DC—DC voltage converter has a controller, two switches, a transformer and two rectifying diodes. The transformer has a first winding, a second winding and a center tap. Input voltage is connected between the center tap and ground. An anode of each diode is connected to the outer ends of the two windings and the cathodes of the two diodes are connected together to provide a positive output with respect to ground. Each switch is connected between an outer end of one winding and ground. The controller generates control signals to turn the switches on and off for limited periods of time in phase opposition to alternately connect the outer ends of the first and second winding to ground to cause current to flow alternatively in one of the windings and induce a voltage in the other winding that is additive to the input voltage, thereby providing an output voltage greater than the input voltage. The converter provides stable operation with good voltage regulation over a wide range of load conditions without the use of feedback.

A system for removal and replacement of core I/O devices while the rest of the computer system is powered-up and operational. The system comprises a custom form-factor core I/O card that contains a plurality of I/O devices, including a processor for managing the cards I/O functions. A command is sent to an operating system, running on a system processor external to the core I/O card, that notifies the system to stop using, and de-configure, the hardware on the core I/O card. Once the OS receives this notification, an indication that the card is ready to be removed is sent to the user. The user then removes the card from its slot and inserts a replacement card into the same slot. The system software then discovers the I/O components on the core I/O card to determine what components are available, and then configures the new I/O device(s).

Logic apparatus filters noise signals on a signal line to a digital circuit. An edge detector determines one or more edges of the noise signals relative to a fast clock. Signals indicative of the edges asynchronously reset a timer; the timer clocks the latch of the signal line when the signal line is stable, and without noise signals detected by the edge detector, for a period defined by a slow clock. The slow clock is slower than the fast clock by several orders of magnitude. The edge detector may be constructed by one flip-flop and an XOR gate. A second flip flop couples to the signal line and the output of the timer to pass through the latched value of the signal line to the digital circuit when clocked by the timer.

A system includes a converter to convert an input voltage to an output voltage, where the converter has an adjustment input. The system further includes a voltage adjustment logic to receive an indication of an electrical current consumed by a load, with the voltage adjustment logic being responsive to the indication of the consumed electrical current to provide a control indication to the adjustment input of the converter to adjust the output voltage from the converter.

A dual power source system includes a first power source and a second power source operably coupled with an electrical device, as well as a switching mechanism capable of selecting between the first and second power sources. An uninterruptible power supply (UPS) is place in line with one of the first and second power sources leading to the electrical device. Sense circuitry is capable of identifying a power failure condition in either the first or second power sources. A controller utilizes signals from the sense circuitry to selectively switch between the first and second power sources while configuring the UPS in a manner of providing for a plurality of operational states that accommodate the electrical device with operational power despite any combination of power failures in the first and second power sources.
