Publication number: 20230327478Abstract: An uninterruptible power supply (UPS) includes a rectifier configured to receive alternating current (AC) power. The UPS further includes a first output connected to the rectifier through an inverter. The first output is configured to output an AC power supply. The UPS also includes a second output connected to the rectifier through a battery backup and a stepdown converter. The second output is configured to output a direct current (DC) power supply in response to a detected power anomaly condition, thereby providing extra redundancy that allows for increased power availability and uptime.Type: ApplicationFiled: June 14, 2023Publication date: October 12, 2023Inventors: Banha SOK, Rameez K.

Patent number: 11011768Abstract: A fuel cell power controller tracks load current and fuel cell output voltage, and alerts on excessive fuel cell ramp rate, so another power source can supplement the fuel cell and/or the load can be reduced. A power engineering process makes efficient use of available fuel cell power by ramping up power flow rapidly when power is available, while respecting the ramp rate and other power limitations of the fuel cell and safety limitations of the load. Power flow decreases after an alert indicating an electrical output limitation of the fuel cell. Permitted power flow increases in response to a power demand increase (actual or requested) from the load in the absence of the alert. Power flow may increase or decrease in a fixed amount, a proportional amount, or per a sequence. A power controller relay may trip open on a low fuel cell output voltage or high load current.Type: GrantFiled: December 19, 2018Date of Patent: May 18, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Di Wang, Sriram Govindan, John J.

Patent number: 10826250Abstract: A power cord is described that includes “in-line” power control functionality. The power control functionality may selectively enable or disable a flow of electrical current through the power cord and/or selectively control an amount of electrical current that is permitted to flow through the power cord. The power control functionality may be activated and/or controlled through the receipt of control signals from an external device. The power cord may be configured to monitor the state of an electronic device to which it is connected and selectively activate and/or modify the operation of the power control functionality in response to the detection of a particular state of the electronic device. The power cord may also be configured to receive and analyze sensor data, and based at least on the analysis, selectively activate and/or modify the operation of the power control functionality.Type: GrantFiled: November 13, 2018Date of Patent: November 3, 2020Assignee: Microsoft Technology Licensing, LLCInventor: John J.

Patent number: 10784712Abstract: A power supply unit (PSU) dynamically limits total recovery current. The PSU includes at least a power input, a power output, a historic maximum power draw memory, an update logic, and a recovery current limiting logic. Some implementations include a latest power measurement register, an hourly max power register, and a rolling max register, and controlling firmware. The update logic monitors a power level. The update logic updates the historic maximum power draw memory to match the monitored level. After a power interruption, the recovery current permitted to flow into the PSU is limited based on the historic usage. The recovery current may be limited in a constant, stepped, or ramped manner. The PSU may also provide power distribution. Multiple PSUs may be treated as a group, allowing an individual PSU to exceed its historic usage while the group's recovery currents are limited to the sum of historic usage levels.Type: GrantFiled: December 19, 2018Date of Patent: September 22, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Shaun L. Harris, John J. Siegler, Banha Sok

Patent number: 10699798Abstract: The present invention extends to methods, systems, and computer program products for testing storage device power circuitry. A storage device controller includes an embedded test program. The storage device controller executes the test program in response to receiving a test command. In one aspect, the test program issues a plurality of different command patterns to test shared power circuitry of storage device components (e.g., shared by an array of NAND flash memory devices). The test program identifies a command pattern that causes a greatest total current draw. In another aspect, the test program issues a specified command pattern (possibly repeatedly) to shared power circuitry to determine if the shared power circuitry fails.Type: GrantFiled: December 5, 2016Date of Patent: June 30, 2020Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Laura Marie Caulfield, Mark Alan Santaniello, J.

Patent number: 10103574Abstract: Technology for concurrently powering equipment from multiple power sources, and the control thereof is disclosed. One example implementation of the technology includes a first power supply that powers equipment from a first power source and a second power supply that also powers the equipment from a second power source while the equipment is being powered by the first power supply. A target direct current (DC) output voltage of at least one of the power supplies is changed, thereby changing a ratio of the power being drawn from the first power supply to the power being drawn from the second power supply.Type: GrantFiled: June 21, 2014Date of Patent: October 16, 2018Assignee: Microsoft Technology Licensing, LLCInventors: John J.

Patent number: 10033210Abstract: A power supply is described herein which provides power to a load, such as a load including one or more computing devices. The power supply uses a slow-response power source (such as a fuel-driven mechanism) to handle a slow-moving component of the demand level presented by the load, and uses a fast-response power source (such as a battery or a capacitor, etc.) to handle a fast-moving component of the demand level. By virtue of this approach, the power supply can manage the load level as it appears to the slow-response power source, allowing, in turn, the slow-response power source to service even fast-changing loads—a task which it could not otherwise perform due to its native limitations.Type: GrantFiled: January 30, 2014Date of Patent: July 24, 2018Assignee: Micrsoft Technology Licensing, LLCInventors: Eric C.

Patent number: 9721660Abstract: A volatile memory data save subsystem may include a coupling to a shared power source such as a chassis or rack battery, or generator. A data save trigger controller sends a data save command toward coupled volatile memory device(s) such as NVDIMMs and PCIe devices under specified conditions: a programmable amount of time passes without AC power, a voltage level drops below normal but is still sufficient to power the volatile memory device during a data save operation, the trigger controller is notified of an operating system shutdown command, or the trigger controller is notified of an explicit data save command without a system shutdown command. NVDIMMs can avoid reliance on dedicated supercapacitors and dedicated batteries. An NVDIMM may perform an asynchronous DRAM reset in response to the data save command. Voltage step downs may be coordinated among power supplies. After data is saved, power cycles and the system reboots.Type: GrantFiled: December 2, 2014Date of Patent: August 1, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Bryan Kelly, Sriram Govindan, John J.
