  • Power managing system and method
    Patent number: 11789480
    Abstract: A power managing system and method are provided. When an under voltage lockout circuit determines that a common voltage of the power managing system is lower than a first lockout voltage, the under voltage lockout circuit outputs a first under voltage lockout signal for controlling one of a plurality of power converters that supplies a highest output voltage to rapidly reduce its output voltage to a zero value. Then, the under voltage lockout circuit outputs a second under voltage lockout signal for controlling another one of the power converters that supplies a lowest output voltage to gradually reduce its output voltage to the zero value.
    Type: Grant
    Filed: February 18, 2022
    Date of Patent: October 17, 2023
    Assignee: ANPEC ELECTRONICS CORPORATION
    Inventors: Tzu-Chien Huang, Hsin-Tsung Hsieh, Shang-Lin Yang
