  • Power system and control method thereof
    Patent number: 10454279
    Abstract: The present invention discloses a power system and a control method thereof. The power system includes a plurality of power devices and a physical wire, where each power device includes a signal pin, a power unit and a control unit. The physical wire is connected to the signal pin of each power device to constitute a synchronization signal line. The logic level of the synchronization signal line is based on the result of wired-AND logic operation according to logic levels of the signal pin of each power device. The control unit controls the signal pin's logic level based on an operating state of the power unit. When any one of the power devices is just turned on, its control unit adjusts an on/off state of the power unit according to the logic level of the synchronization signal line.
