    • A switch power supply includes an AC/DC converter, a DC/DC converter, a battery charge-discharge switching circuit, and a detecting and controlling circuit. The AC/DC converter receives an input AC voltage and converts the input AC voltage into a DC voltage. The DC/DC converter converts the DC voltage into several working voltages required for operating the electronic device. The battery charge-discharge switching circuit is selectively connected to the AC/DC converter or the DC/DC converter and connected to the battery. The detecting and controlling circuit detects the input AC voltage. If the input AC voltage is abnormal, the detecting and controlling circuit issues a control signal to the battery charge-discharge switching circuit. In response to the control signal, the battery issues a discharge voltage to the DC/DC converter and the discharge voltage is converted into the working voltages by the DC/DC converter.
    • 开关电源包括AC / DC转换器,DC / DC转换器,电池充放电开关电路和检测和控制电路。 AC / DC转换器接收输入交流电压,并将输入的交流电压转换为直流电压。 DC / DC转换器将DC电压转换成操作电子设备所需的几个工作电压。 电池充放电开关电路选择性地连接到AC / DC转换器或DC / DC转换器并连接到电池。 检测和控制电路检测输入的交流电压。 如果输入交流电压异常,检测和控制电路向电池充放电开关电路发出控制信号。 响应于控制信号,电池向DC / DC转换器发出放电电压,并且通过DC / DC转换器将放电电压转换为工作电压。

    • A power adaptor is provided. The power adaptor includes a voltage converter, a connecting port, a first transformer and a controller. The voltage converter receives an input voltage and determines whether to convert the input voltage to an output voltage according to an indicating signal. The first transformer includes a primary side and a secondary side. The primary side and the secondary side are coupled to each other, and a first end and a second end of the secondary side are coupled to the connecting port, respectively. The controller generates the indicating signal according to a voltage at the primary side of the first transformer. The connecting port is used to connect to an electrical device, and when the connecting port is electrically connected to the electrical device, a first end and a second end of the secondary side are short to a reference ground end of the secondary side.

    • A battery module and an overcharge protecting method are provided. The overcharge protecting method includes following steps: detecting a battery voltage of a rechargeable battery during a charging process; determining whether the battery voltage is larger than or equals to an upper limit voltage; if no, continuously charging the rechargeable battery until the battery voltage reaches a charging cut-off voltage and then the charging process is ended; if yes, stopping the charging process, reducing the value of the charging cut-off voltage and using the reduced charging cut-off voltage as the charging cut-off voltage in the next charging process. In the subsequent charging process, once the overcharge occurs, the value of the charging cut-off voltage is continuously reduced until the overcharge of the rechargeable battery does not occur during the charging process.
    • 提供电池模块和过充电保护方法。 过充电保护方法包括以下步骤:在充电过程中检测可再充电电池的电池电压; 确定电池电压是否大于或等于上限电压; 如果否,连续充电可充电电池,直到电池电压达到充电截止电压,然后充电过程结束; 如果是,停止充电过程,减少充电截止电压的值,并使用减少的充电截止电压作为下次充电过程中的充电截止电压。 在随后的充电过程中,一旦发生过充电,充电截止电压的值将持续减小,直到充电过程中不会发生充电电池的过充电。
