The power supply unit includes a first power conversion block electrically coupled to convert the electrical power input to a first output power supply share supplied to the common output node. The first power conversion block is configured to decrease output voltage from the first power conversion block based on output current from the first power conversion block reaching a rated current level. A second power conversion block is electrically coupled to convert the electrical power input to a second output power supply share supplied to the common output node. The second power conversion block is configured with a predesignated open circuit voltage setting and is further configured to contribute the second output power supply share to the common output node based on the output voltage at the common output node decreasing to the predesignated electrical voltage setting.Type: GrantFiled: September 30, 2021Date of Patent: January 9, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Chee Kiong Fong, Geoffrey Jason Shew, Suet Fong Tin, Michael R.

Patent number: 11833987Abstract: A hybrid power module is provided. The power module is associated with a truck having a lift gate. The power module includes a super capacitor comprising a bank of capacitors, with the super capacitor being in electrical communication with an alternator of the truck. The power module also includes a battery, a switch, a DC/DC boost converter, and electrical wiring. The electrical wiring connects the capacitor bank and first battery to the switch, and further connects the switch to a motor for the lift gate. The super capacitor and the first battery are positioned in parallel, with the super capacitor and the first battery residing proximate the lift gate. The super capacitor contains enough energy to power the electric motor for the lift gate through at least two operating cycles without the battery, protecting the lift gate if the battery goes weak.Type: GrantFiled: April 14, 2022Date of Patent: December 5, 2023Assignee: Systematic Power Manufacturing, LLCInventors: Robert J. Wood, Sr., Chad E. Hall, Bryce Gregory, Luke Yetto, Daniel A. Patsos, Joseph Agrelo
