    • A power detection jack can be connected with a plurality of power output jacks respectively to receive different power levels. Each of the power output jacks has a first insulation element, and the lengths of the first insulation elements are different from each other. The power detection jack includes a first electrode, a second electrode and a power detection element. The first electrode is disposed inside the power detection jack. The second electrode is disposed outside the power detection jack. The power detection element is disposed between the first electrode and the second electrode. When the power detection jack is connected with one of the power output jacks, the power level provided by the power output jack is determined according to a connection state of the power detection element and the first insulation element.
    • 功率检测插孔可以分别与多个电力输出插孔连接以接收不同的功率电平。 每个功率输出千斤顶具有第一绝缘元件,并且第一绝缘元件的长度彼此不同。 功率检测插座包括第一电极,第二电极和功率检测元件。 第一电极设置在功率检测插座的内部。 第二电极设置在功率检测插座的外部。 功率检测元件设置在第一电极和第二电极之间。 当功率检测插座与其中一个电力输出插座连接时,根据功率检测元件和第一绝缘元件的连接状态确定由电力输出插孔提供的功率电平。

    • A power supply applied to an electronic device for providing power includes a transformer unit, a connector, a pulse-width modulation (PWM) control unit, and a switch unit. The connector is electrically connected with the secondary side of the transformer unit for outputting a first output voltage. The PWM control unit outputs a pulse signal with a first period. The switch unit is electrically connected between the PWM control unit and the primary side of the transformer unit. When the electronic device is connected to the power supply, the connector receives an external control signal, and the PWM control unit adjusts the pulse width of the pulse signal to a second period and transmits the pulse signal with the second period to the switch unit to control the connector to output a second output voltage to the electronic device.
    • 施加到用于提供电力的电子设备的电源包括变压器单元,连接器,脉冲宽度调制(PWM)控制单元和开关单元。 连接器与变压器单元的次级侧电连接,用于输出第一输出电压。 PWM控制单元输出具有第一周期的脉冲信号。 开关单元电连接在PWM控制单元和变压器单元的初级侧之间。 当电子设备连接到电源时,连接器接收外部控制信号,PWM控制单元将脉冲信号的脉冲宽度调整到第二周期,并将第二周期的脉冲信号发送到开关单元 控制连接器以向电子设备输出第二输出电压。
