20080265674 | System And Method For Controlling Voltage And Frequency In A Multiple Voltage Environment - A system that includes a first circuitry, a second circuitry, a first supply unit and a second supply unit; characterized by including a second control unit adapted to determine a level of a second supply voltage supplied by the second supply unit in response to an estimated power consumption of the second circuitry and an estimated power consumption of a voltage level shiftless interface circuitry that receives both the first and second supply voltages. A method for controlling voltage level and clock signal frequency supplied to a system, the method includes providing a first supply voltage to a first circuitry and providing a second supply voltage to a second circuitry; characterized by determining a level of the second supply voltage in response to an estimated power consumption of the second circuitry and an estimated power consumption of a voltage level shiftless interface circuitry that receives both the first and second supply voltages. | 10-30-2008 |
20100117449 | SYSTEM FOR HIGH RELIABILITY POWER DISTRIBUTION WITHIN AN ELECTRONICS EQUIPMENT CABINET - The power conversion system allows for multiple segregated and ground independent power sources to provide redundant power to modules within an electronics equipment cabinet with increased reliability and reduced sensitivity to common fault propagation. The power conversion system provides power conditioning modules having independent supply rails that supply power to each module within an electronics equipment cabinet. FET and diode solid-state control and driver logic enable each individual supply rail. Efficient power distribution is facilitated by primary and hot-backup operation of one or more power conditioning modules. Power conversion is facilitated by one or more input supply power feeds and one or more converter stages. | 05-13-2010 |
20100314938 | POWER SUPPLY CONTROL CIRCUIT - A power supply control circuit includes a first switch unit comprising an input terminal to receive a control signal, and a number of second switch units. The second switch units are each connected between an input power source and a power output terminal. The first switch unit controls the number of second switch units to be turned on in response to the control signal being in a first status, so as to control the number of power output terminals to output corresponding power sources. The first switch unit controls the number of second switch units to be turned off in response to the control signal being in a second status, so as to direct the power output terminals to not output the corresponding power sources. | 12-16-2010 |
20110169331 | ADAPTIVE POWER ARCHITECTURE FOR ELECTRONIC MODULES - 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. | 07-14-2011 |
20120319478 | DC TO DC CONVERTER WITH RIPPLE CANCELLATION - Ripple cancellation techniques are described for various DC to DC converters having multiple parallel phases with magnetically coupled inductors. | 12-20-2012 |
20130147271 | POWER SUPPLY DEVICE, METHOD FOR CONTROLLING THE POWER SUPPLY DEVICE, AND ELECTRONIC APPARATUS - Provided are a power supply device capable of producing a highly-accurate supply voltage at low power consumption, a method for controlling the power supply device, and an electronic apparatus in which the power supply device is incorporated. The power supply device includes a first power supplying part and a second power supplying part which has less output current capacity than the first power supplying part does. The power supply device is configured to control the voltage value of the second voltage produced in the second power supplying part in order to make the first voltage produced in the first power supplying part equal to the second voltage produced in the second power supplying part. | 06-13-2013 |
20130187456 | Sourcing and Securing Dual Supply Rails of Tamper Protected Battery Backed Domain - This invention is a System On a Chip (SOC) requiring two tamper resistant externally generated power supplies. A first, higher power supply powers I/O and analog circuits. A second, lower power supply powers digital circuits and memory. A first voltage monitor circuit powered by said first power supply generates a first output signal when the first power supply is below an operational limit high level. A second voltage monitor circuit powered by said first power supply indicates when the second power supply is above an operational high limit level. A power switch is controlled by the first voltage monitor circuit. This power switch connects the second power supply and second load when closed and isolates them when open. Thus the memory cannot be accessed when the I/O and analog power supply is out of specification. | 07-25-2013 |
20140203639 | RECONFIGURABLE MATRIX-BASED POWER DISTRIBUTION ARCHITECTURE - A power management and distribution (PMAD) system includes a first power supply of a first type, a second power supply of a second type different from the first type and first and second loads. The PMAD system includes a matrix of solid state power controllers (SSPCs) connected between the first and second power supplies and the first and second loads. The matrix is configured to selectively supply each of the first and second loads with a plurality of different power levels based on on/off states of the SSPCs of the matrix. | 07-24-2014 |
