Patent number: 9941704Abstract: A number of load units are connected to receive power from a number of power supply units. A potential load bus is connected to have a voltage level representative of both a total potential power requirement of the number of load units and a total potential power supply capability of the number of power supply units. A first control circuit enables operation of the number of load units when the voltage level on the potential load bus indicates that a sufficient supply of power is available. An actual load bus is connected to have a voltage level representative of both an actual total power consumption of the number of load units and an actual total power supply available from of the number of power supply units. A second control circuit signals an impending loss of sufficient power supply based on the monitored voltage level on the actual load bus.Type: GrantFiled: March 1, 2016Date of Patent: April 10, 2018Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: J. Rothe Kinnard, Robert Cyphers, Brian Benstead

Patent number: 9379579Abstract: A dual asymmetric input power supply architecture for use in power systems employing input power source redundancy. The dual asymmetric input power supply operates from a main input of the power supply when acceptable voltage is present on the main input. If the main input fails or is out of tolerance, power can be supplied from an auxiliary input through a transformer isolated switching converter. The dual asymmetric input power supply architecture maintains the high efficiency of a single-input power supply while providing an auxiliary connection for input power source redundancy.Type: GrantFiled: January 14, 2015Date of Patent: June 28, 2016Assignee: ORACLE INTERNATIONAL CORPORATIONInventor: J.

Patent number: 8552586Abstract: A system for standby power control in a multiple power supply environment is provided. The system includes a plurality of power supplies. Each power supply has a standby voltage output, and has a standby voltage enable signal input. A signal line connects to each power supply at the respective standby voltage enable signal input. A resistance is connected between the signal line and a system reference. The plurality of power supplies are configured such that the resistance determines a number of power supplies that must be available before the standby voltage outputs are activated by the power supplies.Type: GrantFiled: April 26, 2010Date of Patent: October 8, 2013Assignee: Oracle International CorporationInventor: J.

Patent number: 7039817Abstract: Apparatus forming a computer system or such-like is disclosed that includes a central processing unit (CPU) and a power supply unit. The CPU provides a digital voltage ID (VID) signal output indicative of the power supply voltage that it desires to receive. The power supply unit has a control input for receiving a digital VID signal from the CPU. The power output from the unit is then provided to the CPU at a voltage level in accordance with the received digital VID signal. A VID offset generator is interposed between the CPU and the power supply unit. This receives the digital VID signal from the CPU, and modifies it by applying a positive or negative offset. The modified digital VID signal is then passed to the power supply unit, which supplies a voltage to the CPU as per the modified VID signal, rather than the VID signal originally output by the CPU.Type: GrantFiled: January 7, 2003Date of Patent: May 2, 2006Assignee: Sun Microsystems, Inc.Inventors: Andrew S. Burnham, Paul Garnett, J. Rothe Kinnard

In one embodiment a system comprises an electrical subsystem that is powered by a first power supply and second power supply. The system further comprises a hot-swap indicator configured to provide a first user indication to indicate whether the first power supply is hot-swappable depending on whether the first power supply is operating at greater than a predetermined power capacity usage, such as fifty percent. The system may also include a second hot-swap indicator for the second power supply.Type: ApplicationFiled: March 12, 2003Publication date: September 16, 2004Applicant: Sun Microsystems, Inc.Inventors: J.

Patent number: 3949278Abstract: A driving circuit for driving a number of solenoid type devices which have very accurate voltage requirements and which utilizes the inductive kick of both the driven devices and internal transformers to efficiently utilize power. A feedback path is provided to an integrated circuit regulator to provide an indication of the power being consumed by the devices. The integrated circuit regulator, along with accompanying circuitry, regulates the voltage output by a power driver such that the voltage output remains steady regardless of the number of solenoid type devices which are being operated. In addition, a feedback path is also provided from each of the driven devices and the internal transformers to the power source such that when the devices are deenergized logically, the inductive kick from each of the devices and the transformers is applied to the power source for power conservation as well as to prevent the necessity for having heat sinks to dissipate the power.Type: GrantFiled: December 31, 1974Date of Patent: April 6, 1976Assignee: International Business Machines CorporationInventors: J.
