Publication number: 20230369885Abstract: A recovery current controller sets a recovery current cap for a power supply unit (PSU) based on power usage of a server. The power usage is determined based on the power consumption of the server, such as before, during, or after a switch from a default power feed to a backup power feed. The recovery current cap is less than a maximum available power of the PSU, thereby reducing or preventing tripped breakers and/or damaged bulk capacitors.Type: ApplicationFiled: May 13, 2022Publication date: November 16, 2023Inventors: Haowei HSU, John Joseph SIEGLER, Banha SOK, Caroline Elizabeth LICHTENBERGER, Joseph Alek PIASECKI, Scot HEATH

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. KAZI, Shaun L. HARRIS, John J. SIEGLER

Publication number: 20230124698Abstract: A busbar connector includes an insulator body, a positive power delivery contact, a negative power delivery contact, and a side band contact. The insulator body has first prong and a second prong oriented in a longitudinal direction and proximate one another with a gap therebetween. The positive power delivery contact is on a first inner surface of the first prong adjacent the gap, and the negative power delivery contact is on a second inner surface of the second prong adjacent the gap. The side band contact is positioned on the insulator body and insulated from the positive power delivery contact and the negative power delivery contact by the insulator body.Type: ApplicationFiled: December 20, 2022Publication date: April 20, 2023Inventors: Chadd Nathaniel GARTON, Banha SOK, Fredrick Anthony CONSTANTINO

Patent number: 11569751Abstract: A device for providing power to a server rack includes a first AC input port, a second AC input port, a first relay, a second relay, and an output port. The output port is electrically connected to both the first AC input port and second AC input port. The first relay is electrically between the first AC input port and the output port, and the second relay is electrically between the second AC input port and the output port. The first relay and second relay are configured to compare a first phase of a first voltage from the first AC input port to a second phase of a second voltage from the second AC input.Type: GrantFiled: December 22, 2021Date of Patent: January 31, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Banha Sok, Brandon Devaul, Chadd Nathaniel Garton, John Joseph Siegler

Patent number: 11126255Abstract: The present disclosure relates to systems, methods, and computer readable media for enabling a power shelf unit to communicate a power throttle signal to devices of a power rack (or other grouping of devices) via a busbar. In particular, systems disclosed herein involve detecting a trigger condition associated with throttling power on server devices of a server rack. In response to detecting the trigger condition, systems here cause a direct current (DC) power supply voltage to change from an operating voltage to a notification voltage for a period of time to alert or otherwise communicate to server devices coupled to the busbar of the trigger condition. Causing the DC power supply voltage to change to the notification voltage may cause processors on server devices to throttle power consumption in accordance with one or more power capping policies implanted thereon.Type: GrantFiled: June 29, 2020Date of Patent: September 21, 2021Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Banha Sok, Rameez Kadar Kazi, Mark Andrew Shaw, Fredrick Anthony Constantino

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.

Publication number: 20190310697Abstract: A power supply unit includes a set of primary circuits operably coupled to a set of phase pair electrical inputs. The electrical inputs provide an input voltage via alternating current. Each primary circuit receives a phased pair electrical input of the set of phase pair electrical inputs and provides a tap output. A single transformer is operably coupled to each tap output. A single secondary circuit is operably coupled to the transformer to provide an output voltage via a direct current.Type: ApplicationFiled: April 10, 2018Publication date: October 10, 2019Applicant: Microsoft Technology Licensing, LLCInventors: Shaun L.
