Patent number: 10168753Abstract: An apparatus for voltage regulation device adjustment includes a configuration module that determines a configuration of an electronic device, where determining the configuration includes determining which components are installed and information about the installed components. The electronic device includes a voltage regulator device (“VRD”) providing power to one or more of the components. The apparatus includes an environment module that measures one or more environmental variables relating to an operating environment of the electronic device. The apparatus includes a firmware selection module that selects new firmware for the VRD of the electronic device in response to the determined configuration and measured environmental variables, and a firmware update module that replaces previously installed firmware on the VRD with the new firmware. The new firmware includes control settings for the VRD.Type: GrantFiled: October 17, 2016Date of Patent: January 1, 2019Assignee: LENOVO ENTERPRISE SOLUTIONS (SINGAPORE) PTE.

Publication number: 20180316218Abstract: A method includes sensing, using a current sensing circuit of a voltage regulator, an apparent amount of current output from the voltage regulator and identifying a present value of at least one operating parameter for the voltage regulator. The method further includes determining at least one current sense correction factor as a function of the identified present value of the at least one operating parameter, and calculating a corrected amount of current output from the voltage regulator as a function of the apparent amount of the current output and the at least one current sense correction factor. Still further, the method includes reporting the corrected amount of current to an integrated circuit that receives current output from the voltage regulator. The method may be performed in an apparatus, such as a server, that includes the voltage regulator, a baseboard management controller, and the integrated circuit.Type: ApplicationFiled: April 28, 2017Publication date: November 1, 2018Inventors: Brian C.

Patent number: 8472211Abstract: The Power Conversion Unit includes a single stage rectifier circuit that generates a DC voltage which is stored on a first capacitor. A circuit arrangement connected to the first capacitor monitors the DC voltage at the capacitor and other predefined signals to generate signals for smoothing ripples associated with the DC voltage and maintains the DC voltage at a predefined level for a predefined time interval. The holdup and smoothing voltages are generated by developing and storing a high voltage on a second capacitor. A switching device connected to the second capacitor causes energy to flow from the second capacitor into the primary winding of a transformer whose secondary winding are switched to deposit the energy stored in said transformer onto the first capacitor. A circuit for charging the second capacitor is also provided.Type: GrantFiled: September 28, 2009Date of Patent: June 25, 2013Assignee: International Business Machines CorporationInventors: Raymond Mathew Clemo, Jamaica LaQuay Barnette, Alfred L Burress, Randhir Singh Malik
