20100077238 | ENERGY EFFICIENCT POWER SUPPLY SYSTEM - An energy efficient power supply system is disclosed. The energy efficient power supply system comprises a plurality of power supply units and the power supply system may be coupled to the control logic. The control logic may be coupled to the power monitor unit. The power monitor unit may determine a power consumption value, which may represent power requirement of a power consuming system such as a computer system. The control logic may determine the power supply units of the plurality of power supply units that are to be activated to provide power to match the power requirement. The control logic may identify the power supply units that may be activated to operate at a maximum efficiency value while providing power specified by the power consumption value. | 03-25-2010 |
20100169690 | SYSTEM POWER MANAGEMENT USING MEMORY THROTTLE SIGNAL - According to some embodiments, power information associated with a computing system may be monitored. Based on the monitored power information, it may be determined whether a hardware memory throttling signal will be asserted and/or that a processor power control signal will be asserted. | 07-01-2010 |
20100332857 | Reducing power losses in a redundant power supply system - A power supply system includes at least a first power supply module and at least one redundant power supply module. The at least one power supply module supplies power to an output terminal. The at least one redundant power supply module operates in a first state and in a second state. In the first state the second power supply module supplies power to the output terminal. In the second state the second power supply module provides standby power and operates in a burst mode (for example, such as a discontinuous conduction mode). | 12-30-2010 |
20110078479 | METHOD AND APPARATUS FOR REDUCING SERVER POWER SUPPLY SIZE AND COST - Computing and server power supplies are typically sized larger to deliver the maximum power the system may need. However since systems are not often used to capacity a smaller power supply may be used in conjunction with a thermal sensor to monitor a critical component of the power supply defined as the particular component within the power supply whose temperature reaches its maximum allowed limit sooner than any other power supply component when the average (continuous) power may exceed the power supply's max rating. When a critical temperature has been reached, an interrupt signal is generated by the power supply to signal the host to throttle back until the temperature comes back into an acceptable range. | 03-31-2011 |
20120161740 | LOAD ADAPTIVE VOLTAGE REGULATOR - Methods and systems may involve detecting an output voltage of a voltage regulator and sensing an inductor current corresponding to a saturating output inductor of the voltage regulator. A switching frequency signal can be generated based on the inductor current, wherein the voltage regulator may be controlled based on the output voltage and the switching frequency signal. In one example, the switching frequency signal sets a first switching frequency if the inductor current is below a saturation current threshold, and sets a second switching frequency if the inductor current is below the saturation current threshold, wherein the second switching frequency is less than the first switching frequency. | 06-28-2012 |

20140157021 | ENFORCING A POWER CONSUMPTION DUTY CYCLE IN A PROCESSOR - In an embodiment, a processor includes a plurality of cores each to independently execute instructions, a plurality of graphics engines each to independently perform graphics operations; and, a power control unit coupled to the plurality of cores to control power consumption of the processor, where the power control unit includes a power excursion control logic to limit a power consumption level of the processor from being above a defined power limit for more than a duty cycle portion of an operating period. Other embodiments are described and claimed. | 06-05-2014 |
20140218007 | METHOD AND APPARATUS FOR PRECISION CPU MONITORING - Example embodiments of a processor current monitor include a switching voltage regulator including a series-connected LC filter including a first inductor, with the first inductor having an inductance value of L1, a first terminal coupled to a switch and a second terminal coupled to a first node, and with the LC filter further including a first capacitor, with the first capacitor having a capacitance value of C1, a first terminal coupled to the first node and a second terminal coupled to a second node, where the switch is configured to couple the inductor to an input voltage at a selected frequency and with the switching voltage regulator configured to supply an output current from the first node to a processor, an inductor current monitoring element | 08-07-2014 |
