Publication number: 20220037874Abstract: An external power supply system for spindles is revealed. The external power supply system includes a tool holder, a rectifier circuit, an overvoltage protection circuit. and a buck/boost converter. The tool holder receives an external power source of a spindle while the rectifier circuit converts the external power source into a rectified output signal with a power factor through step-down transformation. The overvoltage protection circuit is used to check whether the rectified output signal is larger than an overvoltage signal for outputting an operating potential or a non-operating potential. The buck/boost converter is used for receiving the rectified output signal with the power factor and converting the rectified output signal to an output voltage according to the power factor. Then the output voltage is provided to a load of a low voltage power supply, a high voltage power supply, or a constant voltage power supply.Type: ApplicationFiled: July 19, 2021Publication date: February 3, 2022Inventors: Chien-Hung Liu, Yu-Hung Li

Publication number: 20210026545Abstract: A system comprises a power source and two power rails coupled to the power source. A storage device, comprising a non-volatile memory, a cache coupled to the non-volatile memory, and a control pin, is coupled to the second power rail. A power management controller is coupled to the first power rail and to a control pin of the storage device. The power management controller stops the provision of power via the first power rail and provides a signal to the storage device via the control pin when the provision of power via the first power rail is stopped. The storage device continues to receive power from the second power rail when the provision of power via the first power rail is stopped. The storage device stores data from the cache to the non-volatile memory in response to the receipt of the signal via the control pin.Type: ApplicationFiled: April 16, 2018Publication date: January 28, 2021Applicant: Hewlett-Packard Development Company, L.P.Inventors: Yu-Chen Cheng, Yu-Hung Li
