International Classification:
H02J 1/00 G06F 13/00
US Classification:
307 31, 710100
Abstract:
A system may include a module that includes a component, a logic device to provide an instruction on behalf of the component, and control logic to generate a desired output voltage signal in response to a constant current, where the desired output voltage signal indicates a determined voltage that the component is configured to operate with when performing an operation. The system may include a board that includes a power supply to produce the determined voltage based on the instruction, and an interface to couple the determined voltage to the component to allow the component to perform the operation on behalf of the board, send the constant current to the control logic, and receive the desired output voltage signal from the control logic.
Connection Module For Providing N+N And M+1 Redundant Power Distribution
A device may include an interconnect module that includes a number of ports, where each port is configured to receive both an alternating current (AC) power supply and a direct current (DC) power supply; where the interconnect module provides power from the received power supplies to a plurality of field replaceable units (FRUs).

International Classification:
G05F 1/40
US Classification:
323288, 307139, 379412
Abstract:
A power system includes a switch, a capacitor and a comparator circuit. The power system receives a signal to turn off power supplied to the power system, turns off the switch that is used to supply power to the system and discharges the capacitor. The power system also compares a voltage across the discharging capacitor to a threshold voltage value, and turns on the switch to allow power to be supplied to the power system when the compared voltage across the discharging capacitor equals the threshold voltage value.

US Classification:
307 81, 307 80, 307 82
Abstract:
A device may include a plurality of direct current to direct current (DC/DC) converters that may produce voltages, and a first device that may receive a signal from a second device on a removable module when the removable module is coupled to the device. The first device may produce, based on the signal, an instruction related to one or more voltages associated with the removable module. The instruction may cause a first DC/DC converter and a second DC/DC converter, of the plurality of DC/DC converters, to power up at different times based on a particular sequence, and generate the one or more voltages. The particular sequence may be based on the signal. The first device may cause the one or more voltages, generated by the first DC/DC converter and the second DC/DC converter, to be provided to the removable module.

International Classification:
G05F 1/70
US Classification:
323207, 363127
Abstract:
An active voice-band filter includes a regulator to regulate an input current to the regulator and to convert DC voltage from an input bus to a higher DC voltage at an output of the regulator; an output voltage feedback loop, connected to the output of a regulator, for generating an output voltage value; and a current control loop for generating a control signal to regulate an input current of the regulator, where the control signal is based on an input bus current measurement and a reference voltage value. The reference voltage value is calculated using both of the output voltage value and an input bus voltage signal. The regulator regulates the input current to the regulator, based on the control signal, to reject voice band range current harmonics from the higher DC voltage.

H05K 7/16 H02B 11/12 H01H 9/00
US Classification:
361727, 361609, 200 17 R
Abstract:
A power connection system includes a power attachment assembly (PAA) to house power cables that transport electrical power, where the cables are terminated by a connector associated with the PAA; and a power supply to provide the power to a network device, where the power supply includes another connector and a group of circuit breakers that correspond to the cables. The PAA and the power supply permit the cables to be connected to the power supply, and permit the connector and the other connector to be connected to form a junction via which the power is transported. The circuit breakers, when turned on, permit the power to be received from the cables via the PAA. The system also includes a handle to disconnect the PAA from the power supply in a manner that turns off the circuit breakers prior to disconnecting the PAA from the power supply.
